The present invention relates to a designing support method, a designing support equipment, a program and a computer-readable storage medium, more specifically the invention relates to a designing support method, a designing support equipment, a program and a computer-readable storage medium, which are used in designing various systems such as electric products such as various electric appliances using a computer system, electronic devices or mechanical systems such as various automobiles.
On the initial stage of development of various products provided with electrical connection relationship such as electric products and electronic products, evaluation of the feasibility of whole product is studied based on unfixed various information, and design in such a initial stage of development is called a “concept design”.
More specifically, the concept design means design on the initial stage of design in product development, and planning study, trial production of a product or the like is performed on the stage of concept design.
In short, in the concept design stage, various objects that constitute a product (the object means various product constituent items such as software, circuit parts, chassis parts, chips, modules, interconnect, packages and chassis, which are needed in constituting a product) are simultaneously dealt with, and whether they fulfill functions and designs required in the market is studied while taking all objects in consideration comprehensively.
For example, as an example of a conventional designing procedure, description will be made for a designing procedure in developing a digital camera product. Such a conventional design procedure is divided into a product planning stage (product planning), a function design or specification design stage (function design/specification design), and a mounting design or detail design stage (mounting design/detail design), consideration of purchase or consideration of diversion of existing items from outside (purchase/diversion from outside) is done along with each of the design stages. Then, the product planning stage and the function design/specification design stage generally correspond to the concept design.
Herein, on the product planning stage, what kind of product concept or product outline will be created is considered. Specifically, what kind of catalog spec will be needed is considered, and as the catalog spec of a digital camera,
Power of optical zoom
Power of digital zoom
Necessity of SD card memory compatibility
Necessity of video shooting
Number of inches of liquid crystal display screen and the like, for example, are consideration targets.
After such a product planning stage, procedure moves to a function design/specification design stage in which functions necessary in realizing contents decided in the product planning and its specific realizing method are considered.
On the function design/specification design stage, a central processing operation function, a graphics function, an I/O function and the like are expressed on a logical block diagram.
After that, based on a design in the function design/specification design stage, the mounting/detail design, the purchase/diversion from outside or the like is performed. More specifically, functions and specific realizing methods are classified into actual product constituent items, and each of the product constituent items is individually designed, consideration of purchase or consideration of diversion of existing items from outside is performed.
Specifically, on the mounting/detail design stage, for example, design of semiconductor, design of substrate, design of wire or cable, design of flexible substrate or the like is performed.
Further, on the stage of purchase/diversion from outside, purchase and diversion of flash parts, batteries, battery units, lens modules, liquid crystal panels, panel substrates or the like, for example, are considered.
Herein, description will be further made for the function design/specification design stage. On the function design/specification design stage, the entire system schematic design utilizing a logical block diagram is performed, and in this occasion, designers perform design while referring to reference documents, explanatory materials or past cases.
More specifically, when the designers move on with design, they express design contents by manual graphics on paper, or express design contents by graphics simply using graphic tools such as Visio (trademark) and PowerPoint (trademark). Alternatively, designers do not express anything on a medium at all, but move on with design in designers' imagination.
Herein, although it is possible to grasp the operation image of a product in the logical block diagram, it is unclear specifically what kind of constitution is used to realize operations, so that he/she creates an overall operation image by attaching documents, simple explanatory papers, reference documents, past design examples or the like other than the logical block diagram.
It is to be noted that the “logical block” expresses a unit of product functions. The block is put together by an operation unit in many cases, the level of detail of expressed contents is different for each person who handles the block.
Further, the “logical block diagram” is a diagram in which electric designers list logical blocks, can see each association, and can imagine overall operation when they move on with product design.
Once the operation image of a product is completed as described above, a processing in which the completed operation image is sorted to actual product constituent items is performed. As a work for this processing, a mock-up or a barrack (prototype) is fabricated by handcraft to create a pseudo operation image. In this occasion, he/she only sees the logical block diagram and associated information for reference, so that it is extremely difficult to understand the operation image in accurate contents.
Therefore, sorting of the operation image to product constituent items had to be ambiguous.
It is to be noted that semiconductors, substrates, wires, cables, flexible substrates, flash parts, lens modules, batteries, battery units, liquid crystal panels, panel substrates and the like are fabricated by mock-ups or barracks, for example, in the example of digital camera.
As described, on the concept design stage, evaluation of various matters regarding product development, that is, functions, designs, operation images, cost or time of sales or the like, for example, tends to be very ambiguous. For this reason, not only a major rework occurs on the stage of detail design in which each object is individually designed, but also information exchange between detail designs has to be very frequent, which were pointed out as a cause of design changes.
Further, on the concept design stage, tests are conducted by actually fabricating mock-ups or barracks to confirm whether or not a problem is in a product planning, so it was pointed out that work time and expense increased.
Due to the above-described background, devising has been strongly desired for a method in which various objects such as software, circuit parts, chassis parts, chips, modules, interconnecting, packages, chassis or the like, which constitute a product can be expressed in a very ambiguous state on the concept design, and moreover, environment in which they can be designed and considered from the aspect of function and the aspect of mounting can be provided.
Further, in the concept design, tests need to be performed by actually fabricating mock-ups or barracks, whose work time and expense increase, devising of a method in which such mock-ups or barracks are not fabricated but trial production to test can be executed on a computer has been strongly desired.
It is to be noted that the above-described requests exist not only in the concept design but also in the design on various stages to no small extent, a target field of the design is not only limited to electric products or electronic devices such as various electric appliances but also covers various systems such as mechanical systems like various automobiles.
It is to be noted that prior art that the present applicant knows at the point of filing a patent is as described above and not an invention according to document publicly known invention, so there is no prior art information to be described.
The present invention has been created in view of the above-described various problems that prior art has, and it is an object of the invention to provide a designing support method, a designing support equipment, a program and a computer-readable storage medium in which various objects such as software, circuit parts, chassis parts, chips, modules, interconnecting, packages, chassis and the like, which constitute a product can be expressed in an ambiguous state by using a computer system, and moreover, environment in which they can be designed and considered from the aspect of function and the aspect of mounting is provided, and an outline of whole product or details of each constituent element of a product can be easily designed.
Further, it is an object of the present invention to provide a designing support method, a designing support equipment, a program and a computer-readable storage medium in which the need of performing tests by actually fabricating mock-ups or barracks, whose work time and expense increase is eliminated, and trial production to test can be executed on a computer without fabricating the mock-ups or barracks.
To achieve the above-described objects, in the present invention, a region in which design information logically expressing the electrical operation of objects to be designed is displayed, a region in which design information expressing the objects to be designed in a physical two-dimensional shape is displayed, a region in which design information expressing the objects to be designed in a physical three-dimensional shape is displayed are severally provided as a display region of a display unit in a computer system, the same object to be designed is displayed in three display regions of the display unit.
More specifically, in the present invention, as conceptually shown in
Further, in the present invention, holding matching between the three design information of LPG in real-time is made possible, designing of various products being objects to be designed can be supported while expressing in the three aspects of LPG.
Further, in the present invention, to hold matching between the three design information of LPG, the three design information of LPG are synchronized/interlocked with each other in real-time.
The real time synchronization/interlocking of the three design information of LPG can be realized by controlling so as to refer to the same design information, for example. More specifically, if the three design information of LPG is acquired while referring to the same design information, LPG is consequently expressed so as to change in a synchronized/interlocked manner because the three design information of LPG is based on the same design information. It is to be noted that selecting and displaying any two design information out of the three LPG is also possible.
More particularly, in the present invention, matching between the three design information of LPG is held in real-time, and expressed in three aspects.
More specifically, matching between the three design information being Logical, Physical and Geometrical is held, and each information is expressed in three display regions.
Herein, as described, Logical (L) means design information logically expressing an electrical operation, further, Physical (P) means design information expressed in physical two-dimensional shapes, and Geometrical (G) means design information expressed in physical three-dimensional shapes, and these three pieces of information is synchronized or interlocked with each other in real-time to hold matching.
Further, in the present invention, design information is expressed in logical blocks. More specifically, in expressing design information, an electrical operation is displayed in logical blocks that were logically classified.
Further, in the present invention, two-dimensional physical information regarding a plurality of substrates is expressed. More specifically, in expressing design information, it is displayed in two-dimensional physical information including a plurality of substrates and electrical connection information between the substrates.
Further, in the present invention, three-dimensional physical information (assembly diagram) having electrical design information is expressed. More specifically, in expressing design information, it is displayed in three-dimensional physical information including electrical design information of electric parts, electrical connection information, layer constitution of a printed circuit board or the like.
Further, in the present invention, electric parts including peripheral parts are automatically arranged. More specifically, regarding an electric part selected on the display screen of Logical by performing logical block designation, region designation and part designation, Physical and Geometrical part search is performed in real-time by the operation of drag and drop, and peripheral parts are also appropriately arranged.
Further, in the present invention, automatic generation of a connector and a flexible substrate is performed. More specifically, in arranging parts by the method of the present invention, optimum connector parts are generated at optimum positions on each substrate on the display screens of P and G, and the connectors are physically connected by an optimum flexible substrate.
Herein, the optimum connector part denotes a connector part having the number of pins compatible with the number of signal lines electrically connecting substrates.
Further, the optimum flexible substrate denotes a flexible substrate having a thickness proportional to the number of signal lines connecting substrates.
It is to be noted that connectors on each substrate are physically connected by a flexible substrate on the display screen of G, and a connector part and a flexible substrate are connected by a rubber band on the display screen of P.
Further, in the present invention, automatic changing of connectors and flexible substrates is performed. More specifically, in the case where an electric part is moved between substrates or in the case where an electric part is deleted/added on the display screens of P and G, the number of signal lines electrically connecting substrates is changed. In such occasion, connector part arranged on each substrate is changed to an optimum connector part, and re-arranged on an optimum position on each substrate.
Further, on the display screens of P and G, the flexible substrate is changed to a thickness proportional to the number of signal lines connecting substrates, and the rubber band of P is also changed.
Further, in the present invention, part changing is performed while holding matching between LPG. More specifically, in the case where an electric part on either display screen of L, P and G is changed, logical information, two-dimensional shaped part or three-dimensional shaped part is searched and changed in real-time on the other two display screens. For example, in the case where a circuit code IC1 is changed from part A to part B on the display screen of L, IC1 is changed in real-time to a two-dimensional shaped part B on the screen of P, and IC1 is changed in real-time to a three-dimensional shaped part B on the screen of G.
Further, in the present invention, part deletion is performed while holding matching between LPG. More specifically, when an electric part was deleted on the screen of L, a two-dimensional shaped part and a three-dimensional shaped part on the two display screens of P and G are deleted in real-time to hold matching. For example, in the case where circuit code IC1 was deleted on the display screen of L, IC1 is deleted in real-time from the screens of P and the screen of G.
Further, when an electric part is deleted on either display screen of P and G, a two-dimensional shaped part and a three-dimensional shaped part on the other screen are deleted in real-time to hold matching. For example, in the case where circuit code IC is deleted on the screen of P, IC1 is deleted in real-time from the screen of G.
Meanwhile, in the present invention, it is assumed that the information of L be right, and for this reason, the information that a part was deleted reflects from L to P and G, but does not reflects from P and G to L. However, P and G are synchronized with each other into the same state constantly.
Further, in the present invention, part addition is performed while holding matching between LPG. More specifically, when an electric part is added on either display screen of P and G, a two-dimensional shaped part and a three-dimensional shaped part are added in real-time on the same coordinates on the other screen to hold matching. For example, in the case where circuit code IC2 is added on the coordinate value (X,Y)=(10,20) of on the substrate A on the screen of P, IC2 is added on the coordinate value (X,Y)=(10,20) on the substrate A on the screen of G.
Further, when an electric part is added in a particular logical block on the screen of L and in the case where the logical block is arranged on the screen of P and the screen of G, the two-dimensional shaped part and the three-dimensional shaped part are added in real-time on the screens of P and G.
It is to be noted that P and G are synchronized with each other into the same state constantly in adding a part. However, synchronization from L to P and G is limited to the case where parts are arranged on P and G by the unit of logical block.
Further, in the present invention, part movement (addition of signal line) is performed while hold matching between PG.
More specifically, in moving an electric part on either display screen of P and G, the two-dimensional shaped part and the three-dimensional shaped part are moved in real-time on the same coordinates on the other screen to hold matching. It is to be noted that signal lines also follow simultaneously with the movement of part.
For example, it is assumed that:
Condition 1. IC1 is arranged on the substrate A and IC2 arranged on a substrate B on the screens of P and G;
Condition 2. IC1 and IC2 are electrically connected to each other by a signal line X; and
Condition 3. The signal line X is a signal line crossing the substrates because IC1 and IC2 are arranged on different substrates.
Under these conditions, IC2 is moved from the substrate B to the substrate A on the screen of P. In short, the signal line X crossing the substrates becomes a closed signal line in the substrate A.
In moving the part as described the above, the followings are performed in real-time by the present invention and matching is held.
Deleting one rubber band crossing the substrates on the screen of P.
Making the thickness of a flexible substrate connecting the substrates thinner on the screen of G because one signal line crossing the substrates is deleted.
Changing connector parts arranged on the substrate A and the substrate B to connector parts compatible with the number of signal lines reduced by one.
Further, in the present invention, signal changing is performed while holding matching between LPG. More specifically, in changing connection information (signal line) on the screen of L, the connection information, the connector parts and the thickness of flexible substrates on the two screens of P and G are changed in real-time to hold matching.
For example, it is assumed that the design information is as follows.
Condition 1. IC1 is arranged on the substrate A and IC2 and IC3 are arranged on the substrate B on the screens of P and G;
Condition 2. IC1 and IC2 are electrically connected to each other by the signal line X; and
Condition 3. The signal line X is a signal line crossing the substrates because IC1 and IC2 are arranged on different substrates.
Under these conditions, in the case where the signal line X connected to IC1 is changed to a signal connected to IC3 on the screen of L, the signal line X becomes a signal line connecting IC2 and IC3 in the same substrate. In short, the signal line X crossing the substrates becomes a closed signal line in the substrate.
As described the above, in changing the connection of the signal line X on the screen of L, the followings are performed in real-time by the present invention and matching is held.
Deleting one rubber band crossing the substrates and newly generating a rubber band connecting IC2 and IC3 on the screen of P.
Making the thickness of a flexible substrate connecting the substrates thinner on the screen of G because one signal line crossing the substrates is reduced.
Changing connector parts arranged on the substrate A and the substrate B to connector parts compatible with the number of signal lines reduced by one.
Further, in the present invention, signal deleting is performed while holding matching between LPG. More specifically, in deleting connection information (signal line) on the screen of L, the connection information, the connector parts and the thickness of flexible substrates on the two screens of P and G are changed in real-time to hold matching.
For example, it is assumed that the design information is as follows.
Condition 1. IC1 is arranged on the substrate A and IC2 is arranged on the substrate B on the screens of P and G;
Condition 2. IC1 and IC2 are electrically connected to each other by the signal line X; and
Condition 3. The signal line X is a signal line crossing the substrates because IC1 and IC2 are arranged on different substrates.
Under these conditions, the signal line X connecting IC1 and IC2 is deleted on the screen of L. In short, one signal line crossing the substrates of the substrate A and the substrate B is reduced.
In this occasion, the followings are performed in real-time by the present invention and matching is held.
Deleting one rubber band crossing the substrates on the screen of P.
Making the thickness of a flexible substrate connecting the substrates thinner on the screen of G because one signal line crossing the substrates is reduced.
Changing connector parts arranged on the substrate A and the substrate B to connector parts compatible with the number of signal lines reduced by one.
Further, in the present invention, signal addition is performed while holding matching between LPG. More specifically, in adding connection information (signal line) on the screen of L, the connection information, the connector parts and the thickness of flexible substrates on the two screens of P and G are changed in real-time to hold matching.
For example, it is assumed that the design information is as follows.
Condition 1. IC1 is arranged on the substrate A and IC2 is arranged on the substrate B on the screens of P and G;
Condition 2. IC1 and IC2 are electrically connected to each other by the signal line X; and
Condition 3. The signal line X is a signal line crossing the substrates because IC1 and IC2 are arranged on different substrates.
Under these conditions, a signal line Y connecting IC1 and IC2 is newly added on the screen of L. In short, one signal line crossing the substrates of the substrate A and the substrate B is increased.
In this occasion, the followings are performed in real-time by the present invention and matching is held.
Adding one rubber band crossing the substrates on the screen of P.
Making the thickness of a flexible substrate connecting substrates thicker on the screen of G because one signal line crossing the substrates was increased.
Changing connector parts arranged on the substrate A and the substrate B to connector parts compatible with the number of signal lines increased by one.
Further, in the present invention, input of various information regarding electric design is performed. More specifically, only designated information can be reflected on a designated logical (functional) block of a circuit diagram from information such as a circuit diagram, a parts list and a netlist regarding electric design. In reflecting information, designating a part of the logical (functional) block, the parts list or the netlist in the circuit diagram is made possible.
Further, in the present invention, output of various information regarding electric design is performed. More specifically, only necessary information regarding electric design can be outputted and produced from the circuit diagram by the unit of logical (functional) block, the unit of substrate unit or the like. It is to be noted that the output information denotes information regarding the electric design of the circuit diagram, the parts list, the netlist or the like.
Further, in the present invention, association and reference of various design information are performed. More specifically, information regarding the electric design of the circuit diagram, the parts list, the netlist or the like is associated.

Although the above-described processing of part arrangement described while referring to
Next, in the state shown on
In the example of this part arrangement &L→G→P interlock processing, as shown in
More specifically, in the part movement &L→G→P interlock processing, when the user selects IC2 (74LS00) displayed on the logical display region 18eL by using the mouse as the pointing device 18g (step S1402), the two-dimensional shaped part of 74LS00 is searched from the shape library (step S1404).
Then, the two-dimensional shaped searched on step S1404 is temporarily displayed to allow it to follow the movement of the mouse (drag) (step S1406), and IC2 is dropped and arranged on the substrate B while performing position designation by the mouse on the screen of the physical display region 18eP (step S1408).
It is to be noted that the coordinate value designated by the mouse should be (X,Y,Z)=(10,10,0).
Next, information “IC2: substrate B (X,Y,Z)=(10,10,0)” that IC2 was arranged on the coordinate value designated by the mouse (X,Y,Z)=(10,10,0) is stored in the arrangement information of the database (step S1410).
After that, a signal that the arrangement information was added on the screen of the physical display region 18eP is transmitted to the screen of the geometrical display region 18eG (step S1412), and processings on and after step S1416 are performed on the screen of the geometrical display region 18eG that received the signal (step S1414).
More specifically, the coordinate value of the added IC2 is read out from the arrangement information of the database, and the read-out coordinate value is stored in the memory (step S1416).
Next, the fact that the added IC2 is 74LS00 is read out from the part information of the database, and the read-out 74LS00 is stored in the memory (step S1418).
Furthermore, the three-dimensional shaped part of 74LS00 stored in the memory is searched from the shape library of the database (step S1420), and the searched three-dimensional shaped part is arranged on the coordinate value of IC2 stored in the memory, on the screen of the geometrical display region 18eG (step S1422).
Next, connection of IC2 is searched from the connection information of the database (step S1424), and whether or not the connection information of IC2 exists is judged (step S1426).
In the case of judgment where the connection information of IC2 does not exist in the judgment processing of this step S1426, this processing routine is ended.
On the other hand, in the case of judgment where the connection information of IC2 exists on the judgment processing of step S1426, rubber band is displayed on the screen of the physical display region 18eP based on the searched connection information (step S1428).
Then, based on the searched connection information, a flexible substrate is changed to a thickness proportional to the number of signal lines between a plurality of substrates on the screen of the geometrical display region 18eG (step S1430), and this processing routine is ended.
In short, as shown in
The coordinate value of IC2 as the arrangement information (refer to a of
The two-dimensional shape of IC2 as the objects of Physical objects (refer to b of
The three-dimensional shape of IC2 as the objects of Geometrical objects (refer to c of
Then, the following is added and displayed simultaneously.
Rubber band between IC2 and IC1 as the objects of Physical objects (
And then, the following information is added.
Flexible substrate is made thicker in proportion to the number of signal lines as the objects of Geometrical objects.
More specifically, since Logical objects, Physical objects and Geometrical objects share the connection information, rubber band showing electrical connection is displayed synchronously with the connection information inputted on the logical display region 18eL simultaneously with the arrangement of a part on the physical display region 18eP.
Next, in the state shown on
In the example of L→P→G interlock processing associated with this signal deleting, as shown in
More specifically, in the signal deleting &L→P→G interlock processing, when the user deletes the signal line SIG1 displayed on the logical display region 18eL by using the mouse as the pointing device 18g (step S1602), the information of SIG1 is deleted from the connection information of the database (step S1604), and the information of SIG1 is deleted from Physical objects of the database (step S1606).
After that, signal that the connection information was deleted on the screen of the logical display region 18eL is transmitted to the screen of the physical display region 18eP and the geometrical display region 18eG (step S1608), the rubber band of SIG1 is deleted on the screen of the physical display region 18eP that received the signal (step S1610), the flexible substrate is change to a thickness proportional to the number of signal lines between a plurality of substrates on the screen of the geometrical display region 18eG that received the signal (step S1612), and this processing routine is ended.
In short, as shown in
The connection information between IC1 and IC2 of the signal name SIG1 is deleted from the connection information (refer to a of
SIG1 is deleted from Physical objects and the rubber band is also deleted from the screen of the physical display region 18eP (refer to b of
The flexible substrate is made thin proportionally to the number of signal lines as the objects of Geometrical objects.
More specifically, since Logical objects, Physical objects and Geometrical objects share the connection information, information regarding the physical display region 18eP and the geometrical display region 18eG is also automatically changed simultaneously with the deletion of a signal line on the logical display region 18eL so as to hold matching.
In the above, description was made that the shape of the flexible substrate was changed together with the change of a signal line between a plurality of substrates, but a connector connecting the flexible substrates on the above-described plurality of substrates and a printed board arranged is also automatically changed to a connector having the number of pins suitable to the signal line between the above-described plurality of substrates.
Next, description will be made for a processing of automatic arrangement of electric parts including peripheral parts (automatic arranging processing) which is executed by the computer system 10.
Herein,
Meanwhile, as a designation method of items to be arranged on the physical display region 18eP, designation by “logical block”, “region” and “part” can be performed.
Hereinafter, description will be made in detail for the automatic arranging processing being the processing of automatic arrangement of electric parts including peripheral parts by referring to each drawing on and after
In Each drawing on and after
To make the present invention easily understood, it is assumed that circuit parts automatically arranged in the example below are shown in
More specifically, it is assumed that circuit parts to be automatically arranged are illustrated in
First, description will be made for the processing method of “(1) Decision of a key device” by referring to a flowchart showing the processing routine of the automatic arranging processing shown in
More specifically, when the processing routine of the automatic arranging processing is activated, the processing of “(1) Decision of a key device” is performed on step S2202 to step S208.
Specifically, when the user selects parts that need to be automatically arranged on the logical display region 18eL by using the pointing device 18g (step S2202) whether or not selected part is plural is judged on step S2202 (step S2204).
In the judgment processing on step S2204, in the case of judgment that the selected part is not plural, more specifically, is single, the part selected on step S2202 is arranged on a designated position (step S2206) and this processing routine is ended.
On the other hand, in the judgment processing on step S2204, in the case where the selected part is judged to be plural, a part having the largest number of terminals is searched out of the selected parts, the searched part having the largest number of terminals is stored in the memory as a key device (step S2208).
More specifically, the part having the largest the number of terminals is decided as a key device as described above, and the example shown in
Meanwhile, in deciding a key device, it goes without saying that an arbitrary part may be manually decided as a key device instead of deciding a part having the largest number of terminals as a key device as described above.
Next, description will be made for the above-described processing method “(2) Decision of arranging order of circuit parts” while referring to a flowchart showing the processing routine of the automatic arranging processing shown in
Herein, in the present invention, arranging order of parts is decided starting from the largest number of signal lines connected to the key device, and the processing of “(2) Decision of arranging order of circuit parts” is executed by step S2210 to step S2212.
Specifically, the parts selected on step S2202 are arrayed starting from the largest number of signal lines connected to the key device and stored in the memory (step S2210), a part that is not signal-connected to the key device out of the parts selected on step S2202 is stored in the memory as an unconnected part (step S2212).
The example shown in
Herein, assuming that each signal line of P1, P2, P3, P4 is S1, S2, S3, S4 as illustrated in
P2 . . . 2 (signal lines S1, S2)
P3 . . . 1 (signal line S3)
P4 . . . 0 (no signal line)
And the arranging order is decided in P2→P3→P4.
It is to be noted that the arranging order should only be decided based on the determination standard below, for example, in the case where the number of signal lines is the same.
More specifically, first, in the case where the number of signal lines is the same, the judging standard that parts are arranged “starting from the largest number of terminals of part” is used, then, the judging standard that parts are arranged “starting from the largest part area” is used in the case where the number of terminals is the same, and then, the judging standard that parts are arranged “starting from the largest registration number in the shape library (Registration No.)” is used in the case where the part area is the same.
It is assumed that registration numbers are given to shapes registered with the shape library in the order starting from the earliest registration of each shape as shown in
Therefore, in deciding an arranging order of parts below, for example, parts are compared by the number of signal lines first.
Part A (number of signal lines 2, number of terminals 14, part area 50 mm2)
Part B (number of signal lines 2, number of terminals 14, part area 40 mm2)
However since the number of signal lines is the same on 2, comparison will be done by the part area next.
Herein, since the number of terminals is the same on 14, comparison will be done in the part area next, in which the part area of part A is judged to be larger, and the arranging order is decided that part A is arranged first and then part B is arranged (part A part B).
In the case where the part area is the same, it is decided that a part having a larger registration number in the shape library should be arranged first.
The registration number in the shape library is a number given when a part is registered with the shape library as described, which is a unique number given by each shape registered, and an arranging order can be uniquely decided. A part having a larger registration number is a part having a newer order registered with the shape library.
When part X and part Y shown in
Next, description will be made for the processing method of “(3) Arrangement of circuit parts according to the arranging order decided in (2) above” while referring to a flowchart showing the processing routine of the automatic arrangement processing shown in
Herein, in the present invention, the processing of “(3) Arrangement of circuit parts according to the arranging order decided in (2) above” is performed on step S2214 to step S2228.
Specifically, each part shape stored in the memory on step S2210 and step S2212 is called from the shape library, and each part shape called from the shape library is stored in the memory (step S2214).
Next, the arranged angle and the arranging coordinates of each part are decided in the order stored on step S2210 around the key device, and stored in the memory (step S2216). Herein, regarding the coordinate value of each part, a position having the shortest route wiring length between key devices is decided as arranging coordinates.
After that, the arranged angle and the arranging coordinates of an unconnected part stored in the memory on step S2212 are decided stored in the memory (step S2218). Herein, regarding the coordinate value of each part, a position having the shortest route wiring length between connected parts is decided as arranging coordinates.
Next, the shape of key device is temporarily displayed such that the origin of key device follows the mouse (step S2220), and each part selected on step S2202 is arranged around the temporarily displayed key device and temporarily displayed (step S2222). In this occasion, each part is arranged on arranging coordinates at an arranging angle decided on step S2216 and step S2218. Further, each part is displayed in the part shape stored in the memory on step S2214.
Then, when the user designates an arranging position on the screen of the physical display region 18eP by using the pointing device 18g (step S2224), the coordinate value designated on the screen of the physical display region 18eP is used as the origin of the key device part, and the part is arranged in the temporary displayed state on step S2222 (step S2226).
Then, the arranging angle and the arranging coordinates of the parts selected on step S2202 are stored in the arrangement information of the database (step S2228), and this processing routine is ended.
Specifically, in the processing of “(3) Arrangement of circuit parts by the arranging order decided in (2) above”, the part P1 decided by the processing of “(1) Decision of key device (primary parts)” is used as a key device, and each circuit part is arranged based on the arranging order of the peripheral parts, which is P2→P3→P4, by the processing of “(2) Decision of arranging order of circuit parts”.
First, description will be made for a processing of arranging the part P2 by using the part P1 as a standard, the part P1 and the part P2 are connected by a signal line S1 and a signal line S2. Now, taking in consideration that the signal line S1 is connected by a wiring pattern, it should be an letter L distance instead of a rectilinear distance.
Herein, as shown in
Rectilinear distance=(X12+Y12)1/2
instead of
Letter L distance=(X1+Y1)
P2 is arranged at a position where the signal route length becomes the shortest and the parts P1 and P2 maintain a designated foil-to-foil distance.
Now, since P2 is connect with P1 by two signal lines of S1 and S2, P2 is arranged at a position where the total of the two signal route lengths of S1 and S2 becomes the shortest.
More specifically, assuming that the distance of the signal line S2 in X direction is X2 and the distance in Y direction is Y2, the part P2 is arranged at a position where the following becomes the shortest.
Route wiring length between P1 and P2 (signal route length)=(X1+Y1)+(X2+Y2).
Next, description will be made for a processing where parts P3 and P4 are arranged by using the part P1 as a standard while referring to
Herein, similar to the one described above, assuming that the distance of the signal line S3, to which the part P3 is connected, in X direction is X3 and the distance in Y direction is Y3, the route wiring length (signal route length) of S3 becomes as follows.
Route wiring length between P1 and P3 (signal route length)=(X3+Y3)
Meanwhile, to decide arranging angle of parts, a state where they are registered with the shape library is set as angle θ°, the signal route length is calculated in the order of 0°→90°→180°→270°, and the parts are arranged at an angle having the shortest signal route length.
In the case where the signal route length is the same, priority is set as follows, and the angle is decided to an angle having higher priority.
For example, in the case where the signal route length is the same in the arranging angles of part 0° and 180°, the arranging angle of part is decided to 0° having higher priority.
On the other hand, since the part P4 is not connected to the key device P1, it is arranged at a position having the shortest route wiring length (signal route length) to the part P3 of a connecting destination in this case.
Similar to the one described above, assuming that the distance of the signal line S4 in X direction is X4 and the distance in Y direction is Y4, the signal route length of S4 becomes as follows.
Route wiring length between P3 and P4 (signal route length)=(X4+Y4)
In the case of a plurality of positions having the same signal route length, parts are arranged at a position having the shortest distance from the key device.
By the processing described above, positional relation between the key device and the peripheral parts can be decided.
Now, regarding the arranging positions on the substrate, peripheral parts are arranged while using a position designated by the mouse or the like is used as the origin of the key device.
Next, description will be made for another example of the processing of automatic arrangement of electric parts including peripheral parts (automatic arranging processing) executed by the computer system 10, specifically, for a method in which a plurality of substrates blocks are connected by the connector and the flexible substrate (hereinafter, appropriately referred to as “flex substrate”) according to the electrical connection information. More specifically, description will be made for a method in which substrate blocks, which are not electrically connected to each other, are connected by the connector and the flex substrate.
It is to be noted that a function realized by such a method (hereinafter, appropriately referred to as “connecting function of a plurality of substrates”) works in an operation as shown in
More specifically,
In this processing, the electrical connection information defined in the logical display region 18eL is searched based on instruction coordinates by the character input device 18f or the pointing device 18g, the connector and the flex substrate are generated and the connection information is displayed by rubber band via the connector and the flex substrate, on the physical display region 18eP, and the connector and the flex substrate are generated on the same position as that on the physical display region 18eP and the state where parts are connected by the connector and the flexible substrate having the three-dimensional shape is displayed on the geometrical display region 18eG.
More particularly, on the logical display region 18eL, the connecting function of a plurality of substrates works when a circuit element or a circuit element group is selected by either one of the methods such as a to c below, parts are arranged on the physical display region 18eP by drag and drop, and there is electrical connection with another substrate on the physical display region 18eP.
a. Function (circuit) block designation
b. Region designation
c. Designation of one or more parts
Further, as shown in
Now, before executing connection by connector displaying connection by a rubber band without a connector based on the connection information is also possible.
As a result of the working of the connecting function of a plurality of substrates, a plurality of substrates are connected on the physical display region 18eP and the geometrical display region 18eG as shown in
Then, in the connecting function of a plurality of substrates, connection between a plurality of substrates is performed by taking the electrical connection information described below in consideration.
Further, in the connecting function of a plurality of substrates, optimum connector and flex substrate are generated on optimum positions, and to realize this, the connecting function of a plurality of substrates performs processings as shown below.
Processing 1: Deciding a connecting medium such as optimum connector and flex substrate according to the number of signal lines
Processing 2: Performing pin assignment where each signal line is connected to terminals of a connecting medium such as a connector and a flex substrate
Processing 3: Generating a connector at a position having the shortest route of electric signal
By these Processing 1 to Processing 3, optimum connector and flex substrate are generated on optimum positions.
In the following, description will be made in detail for each processing of Processings 1 to 3 while referring to the flowchart shown in
In the computer system 10, when the user arranges a part on the physical display region 18eP or executes connection between substrates by connector (step S2502) whether or not two or more substrates exist on the physical display region 18eP and the geometrical display region 18eG is judged (step S2504), and in the case of judgment where two or more substrates exist on the physical display region 18eP and the geometrical display region 18eG, processings on step S2506 and after are performed, and the connecting function of a plurality of substrates works.
Now, in this embodiment, to make the present invention easily understood, a processing of deciding and connecting a connectors and a flex substrates to be generated will be described by using the case shown in
First, description will be made for Processing 1 executed by step S2506 to step S2514.
In Processing 1, all combinations of two substrates are extracted for all substrates first, and the extracted result is stored in the memory (step S2506). In the example shown in
When the processing on step S2506 ended, a signal line connecting substrates is searched in the extracted combinations on step S2506 and in the case where the existence of a signal line connecting substrates is searched (step S2508, step S2510), the searched result is stored in the memory (step S2512). In the example shown in
Substrate A-B→SIG1, STG2 (2 signal lines)
Substrate A-C→None
Substrate B-C→SIG3 (1 signal line)
Then, connectors and flex substrates, which have the number of pins according to the number of signal lines stored in the memory on step S2512 are searched from the shape library of the database, connectors and flex substrates, which have the number of pins according to the number of signal lines stored in the memory on step S2512 are decided and stored in the memory (step S2514). In the example shown in
Between substrate A-B: 2-pin connector, 2-terminal flex substrate
Between substrate A-C: No connector and flex substrate
Between substrate B-C: 1-pin connector, 1-terminal flex substrate
Next, describing Processing 2 executed on step S2516, connection destinations of the signal lines searched on step S2508 to step S2512 are allocated sequentially from the first pin of the connector stored on step S2514 (step S2516).
More specifically, describing Processing 2 being the pin assignment of each signal line on step S2516 by using
SIG1→No. 1 pin of connector A, No. 1 pin of connector B1
SIG2→No. 2 pin of connector A, No. 2 pin of connector B1
SIG3→No. 1 pin of connector B2, No. 1 pin of connector C
Then, the connection information and connector pins are set.
Next, description will be made for Processing 3 executed on step S2518 to step S2530.
In the explanation of Processing 3, on step S2518 first, the signal lines searched on step S2508 to step S2512 are divided into two by using the connector as a boundary and makes them become signal lines converged in the substrate connected to the connectors, (hereinafter, appropriately referred to as “connector signal”). Specifically, as shown in
Next, on step S2520, regarding one of the two substrates extracted on step S2506, the sum of the route lengths of one or more connector signals is set to ΣXY1.
When description is made according to the example shown in
Signal route length in the substrate A=Signal route length of SIG1-1+Signal route length of SIG2-1−(X1+Y1)+(X2+Y2)
When the processing of step S2520 ends, procedure proceeds to the processing of step S2522, regarding the other one of the two substrates extracted on step S2506, the sum the route lengths one or more connector signal is set to ΣXY2.
When description is made according to the example shown in
Signal route length in the substrate B=Signal route length of SIG1-2+Signal route length of SIG2-2=(X3+Y3)+(X4+Y4)
When the processing of step S2522 ends, procedure proceeds to the processing of step S2524, and the rectilinear distance between connectors of two substrates is set to ΣXYX.
When description is made according to the example shown in
Signal route length=(X52+Y52+Z52)1/2
When the processing of step S2524 ends, procedure proceeds to the processing of step S2526, positions of connectors where the sum of ΣXY1, ΣXY2 and ΣXYX becomes the minimum is calculated, and the connectors are arranged on the screens of P and G.
When description is made according to the above-described example, a signal route length between the substrate A and the substrate B becomes as follows based on the above.
Signal route length=Signal route length in the substrate A+Signal route length in the substrate B+Signal route length between the substrate A and the substrate B=(X1+Y1)+(X2+Y2)+(X3+Y3)+(X4+Y4)+(X52+Y52+Z52)1/2
Positions at which the signal route length becomes the minimum is calculated by the equation above, and connectors are arranged.
When the processing of step S2526 ends, the flex substrate that suit the connector shapes are generated on the screen G (step S2528), then, flex substrates that suit connector shape are generated on the screen P, the connection information between the connectors and the flex substrates is displayed in a rubber band (step S2530) and this processing is ended.
When description is made according to the above-described example, the flex substrates are generated in a width according to connector widths (pin shape), and as shown in a round frames in
It is to be noted that the above-described embodiment can be modified as shown in (1) to (7) below.
(1) In the above-described embodiment, the printed circuit board was taken as an object, it goes without saying that the invention is not limited to this, and various objects such as a unit, a module part, a semiconductor chip, a chassis and a chassis part shown in
Further, as shown in
(2) In the above-described embodiment, description has been made for the case of holding matching of the display state between the logical display region 18eL, the physical display region 18eP and the geometrical display region 18eG on the display unit 18e in the single client system 18, but it goes without saying that the present invention is not limited to this, and the invention is also applicable to the case of holding matching of the display state between the logical display region 18eL, the physical display region 18eP and the geometrical display region 18eG in the display units (display) 18e of a plurality of client systems 18c, which will be described in detail below.
First, description will be made for operating environment while referring to
Further, a client system 18C operated by Mr.C having the display unit 18e equipped with the logical display region 18eL, the physical display region 18eP and the geometrical display region 18eG is connected on a WAN (Wide Area Network: wide area network), and is accessible to the WWW server system 14.
In the operating environment, it is assumed that nothing is displayed on the display screen of the display unit 18e of the client system 18A, the display screen of the display unit 18e of the client system 18B and the display screen of the display unit 18e of the client system 18C, in the initial state.
From this initial state, as shown in
In the state shown on
Herein,
More specifically, by the operation of the pointing device 18g of the client system 18B, synchronization button 102 displayed on the display screen of the display unit 18e is clicked to open a synchronization designating window 104, and then, by inputting “A” that designates the client system 18A in a column of terminal to be synchronized 104a in the synchronization designating window 104 by the operation of the character input device 18f of the client system 18B, and designation of the client system 18A with which the client system 18B synchronizes is completed. Since synchronization is not completed yet, the display screen of the display unit 18e of the client system 18B is not changed at all.
Herein, when an OK button 104b of the synchronization designating window 104 is clicked by the operation of the pointing device 18g of the client system 18B, synchronization is executed, information that “synchronize the client system 18A and the client system 18B” is transmitted from the client system 18B to the WWW server system 14, and the information is stored in the memory of the WWW server system 14.
When the synchronization is completed, the same contents as the displayed contents of the logical display region 18eL, the physical display region 18eP and the geometrical display region 18eG on the display screen of the display unit 18e of the client system 18A are displayed on the logical display region 18eL, the physical display region 18eP and the geometrical display region 18eG on the display screen of the display unit 18e of the client system 18B.
Then, on the display screen of the display unit 18e of the client system 18A and the display screen of the display unit 18e of the client system 18B, two mouse pointers that are a mouse pointer 106 (pointing-finger shape A) for performing the operation of the client system 18A by Mr.A and a mouse pointer 108 (pointing-finger shape B) for performing the operation of the client system 18B by Mr.B are severally displayed.
It is to be noted that synchronization information “synchronization A-B” showing that the client system 18A and the client system 18B were synchronized with each other is stored in the memory of the WWW server system 14 with the processing of this synchronization.
Furthermore, a synchronization list screen 110 is displayed on the display screen of the display unit 18e of the client system 18A and the display screen of the display unit 18e of the client system 18B, and “A” and “B” showing that the client system 18A and the client system 18B are synchronized with each other and displayed on the synchronization list screen 110.
Next, in the state shown on
Herein,
Further,
In the following, description will be made for a processing in which the display screen of the display unit 18e of the client system 18C and the display screen of the display unit 18e of the client system 18A are synchronized, and because the operation processing on the display screen of the display unit 18e of the client system 18C is similar to the operation processing on the display screen of the display unit 18e of the client system 18B,
First, an instruction of executing synchronization designating the client system A by the client system C is performed (step S3802). Specifically, by the operation of the pointing device 18g of the client system 18C, a synchronization button 102 displayed on the display screen of the display unit 18e is clicked to open a the synchronization designating window 104, and then, by inputting “A” that designates the client system 18A in the column of terminal to be synchronized 104a in the synchronization designating window 104 by the operation of the character input device 18f of the client system 18C, designation of the client system 18A with which the client system 18B synchronizes is completed. Since synchronization is not completed yet, the display screen of the display unit 18e of the client system 18C is not changed at all. Then, by the operation of the pointing device 18g of the client system 18C, an OK button 104b on the synchronization designating window 104 is clicked to instruct execution of synchronization.
When the execution of synchronization is instructed by clicking the OK button 104b, information “synchronize the client system 18A and the client system 18C” is transmitted from the client system 18C to the WWW server system 14, and the information is stored in the memory of the WWW server system 14 (step S3804).
Thus, synchronization information between the client system 18A and the client system 18C to be synchronized is searched from the synchronization information stored in the memory of the WWW server system 14 (step S3806), and whether or not the synchronization information of the client system 18A or the client system 18C exists is judged (step S3808).
In the case of judgment where the synchronization information of the client system 18A or the client system 18C exists by this judgment processing of step S3808, the existing synchronization information is changed (step S3810), and the processing of step S3814 (described later) is performed.
On the other hand, in the case of judgment where the synchronization information of the client system 18A or the client system 18C does not exist by the judgment processing of step S3808, synchronization information is newly added (step S3812), and the processing of step S3814 (described later) is performed.
Then, on step S3814, synchronization information “synchronization A-C” showing that the client system 18A and the client system 18C were synchronized with each other is stored in the memory of the WWW server system 14, but in such occasion, the synchronization information “synchronization A-B” showing that the client system 18A and the client system 18B were synchronized with each other is already stored in the memory of the WWW server system 14, and this means that all of the client system 18A, the client system 18B and the client system 18C are synchronized, so that the WWW server system 14 stores the synchronization information “synchronization A-B” and the synchronization information “synchronization A-C” by rewriting into synchronization information “synchronization A-B-C” showing all of the client system 18A, the client system 18B and the client system 18C were synchronized with each other. Then, the synchronization information “synchronization A-B-C” is transmitted to the client system 18A, the client system 18B and the client system 18C being all terminals that they were synchronized with each other by the synchronization information “synchronization A-B-C”.
Next, the client system 18A, the client system 18B and the client system 18C being each terminal that received the synchronization information “synchronization A-B-C” synchronizes each display screen of the display unit 18e to display the logical display region 18eL, the physical display region 18eP and the geometrical display region 18eG, and displays the synchronization list screen 110 on each display screen of the display unit 18e, and displays “A”, “B” and “C” showing the synchronization information “synchronization A-B-C” expressing that the client system 18A, the client system 18B and the client system 18C are synchronized with each other on the synchronization list screen 110 (step S3816).
Next, the client system 18A, the client system 18B and the client system 18C being each terminal that received the synchronization information “synchronization A-B-C” transmits a self terminal name being each terminal name, that is, whether it is the client system 18A, the client system 18B or the client system 18C and the current coordinate value of each mouse pointer to the WWW server system 14 (step S3818).
Then, the WWW server system 14 that received the information transmitted by the processing of step S3818 searches synchronization information containing the received self terminal name from the memory (step S3820) and transmits the coordinate value of each mouse pointer to other terminals except the self terminal to synchronized terminals shown by the searched synchronization information, that is, the client system 18A, the client system 18B and the client system 18C (step S3822).
Then, the client system 18A, the client system 18B and the client system 18C being each terminal that received the coordinate value of the mouse pointer transmitted by the processing of step S3822 displays the mouse pointer on the coordinate value on the display screen of the display unit 18e (step S3824), and this processing is ended.
As described above, although the client system 18C only designated synchronization with the client system 18A, the client system 18C becomes synchronized with not only the client system 18A but also the client system 18B because the client system 18A is already synchronized with the client system 18B, and when synchronization is completed, the same contents as the displayed contents of the logical display region 18eL, the physical display region 18eP and the geometrical display region 18eG on the display screens of the display units 18e of the client system 18A and the client system 18B are displayed on the logical display region 18eL, the physical display region 18eP and the geometrical display region 18eG of the display screen of the display unit 18e of the client system 18C.
Then, on the display screen of the display unit 18e of the client system 18A and the display screen of the display unit 18e of the client system 18B and the display screen of the display unit 18e of the client system 18C, three mouse pointers that are the mouse pointer 106 (pointing-finger shape A) for performing the operation of the client system 18A by Mr.A, the mouse pointer 108 (pointing-finger shape B) for performing the operation of the client system 18B by Mr.B and a mouse pointer 112 (pointing-finger shape C) for performing the operation of the client system 18C by Mr.C are severally displayed.
Further, the synchronization information stored in the memory of the WWW server system 14 is changed to the synchronization information “synchronization A-B-C” that the client system 18A, the client system 18B and the client system 18C are synchronized with each other.
Then, on and the display screens of the display units 18e of the synchronization list screen 110 in the client system 18A, the client system 18B the client system 18C, “A”, “B” and “C” showing the synchronization information “synchronization A-B-C” that the client system 18A, the client system 18B and the client system 18C are synchronized with each other is displayed.
Herein, description will be made for an editing processing in the case where the client system 18A, the client system 18B and the client system 18C were synchronized with each other. In the case where the client system 18A, the client system 18B or the client system 18C perform the editing processing, the editing processing is started or restarted after a display region that becomes a target of the editing processing is selected from the logical display region 18eL, the physical display region 18eP and the geometrical display region 18eG of the display screen of the display unit 18e, in each of the client system 18A, the client system 18B or the client system 18C.
It is to be noted that displaying the operation process of other terminals in real-time is also possible by performing a processing similar to the one described above on the display screen of the display unit 18e of each terminal.
More specifically, when any operation such as moving or clicking of the mouse 18g in each terminal and operation of the keyboard 18f is performed, a processing that operation contents in each terminal are transmitted to the WWW server system 14, the operation contents are transmitted from the WWW server system 14 to another terminal being synchronized, and the operation contents are reflected on another terminal should only be performed.
Further, for example, in the case where the client system 18B selected the logical display region 18eL when the client system 18A selected the logical display region 18eL earlier, the editing processing in the logical display region 18eL is enabled on the client system 18B that selected the region later, and the client system 18A enters a state where it does not select any display region.
Then, in the case where the client system 18B selected the logical display region 18eL after the client system 18A as described the above, display on all synchronized terminals is changed into the state that the client system 18B selected the logical display region 18eL.
Hereinafter, description will be made for a processing when the client system 18B selected the logical display region 18eL in the state where the client system 18A selected the logical display region 18eL, the client system 18B selected the physical display region 18eP, and the client system 18C selected the geometrical display region 18eG, while referring to the flowchart shown in
First, when the client system 18B selects the logical display region 18eL (step S4002), the client system 18B transmits information that it selected the logical display region 18eL to the WWW server system 14 (step S4004).
The WWW server system 14 that received the transmitted information in the processing of step S4004 searches the synchronization information of the client system 18B from the synchronization information stored in the memory (step S4006), and judges whether or not the synchronization information of the client system 18B exists (step S4008).
In the case of judgment where the synchronization information of the client system 18B does not exist in the judgment processing of this step S4008, this processing is ended.
On the other hand, in the case of judgment where the synchronization information of the client system 18B exists in the judgment processing of step S4008, procedure advances to the processing of step S4010, and screen selection information made up of a and b below is transmitted to the client system 18A and the client system 18C being all synchronized terminals shown by the synchronization information.
a: An editing terminal being a terminal that edits the logical display region 18eL is the client system 18B
b: The geometrical display region 18eG that the client system 18B selected immediately earlier has not been selected by any terminal (no editing terminal)
When the above-described processing on step S4010 ended, procedure advances to the processing of step S4012, the client system 18A and the client system 18C being the terminals that received the screen selection information transmitted in the processing of step S4010 change the selection state of the display regions to a and b below, and this processing is ended.
a: Change editing terminal being a terminal that edits the logical display region 18eL the client system 18B
b: Change to no terminal that edits the geometrical display region 18eG (no editing terminal)
Now, in the present invention, in the middle of editing each terminal interrupting operation can be performed from a terminal synchronizing with the terminal in the middle of editing (synchronized terminal).
For example, when the logical display region 18eL is selected on the client system 18B while editing the data of the logical display region 18eL by the client system 18A, the editing processing of the client system 18A is interrupted, and the operation of the client system 18B becomes effective.
Furthermore, when the logical display region 18eL is selected by the client system 18A, editing can be re-started from an operation at the point where the editing processing was interrupted by the client system 18A.
Further, in the present invention, terminals are controlled such that the same object cannot be edited by a plurality of terminals.
Description will be made for this specifically while referring to
Herein, when the client system 18B attempts to edit IC1 on the logical display region 18eL or the geometrical display region 18eG, editing is unable due to the status that the client system 18A being another terminal is editing the object.
(3) In the above-described embodiment, description was made mainly for the case of reflecting the processing contents in the logical display region 18eL on the physical display region 18eP or the geometrical display region 18eG. However, it goes without saying that the present invention is not limited to this, and the processing contents in the physical display region 18eP may be reflected on the logical display region 18eL or the geometrical display region 18eG, or the processing contents in the geometrical display region 18eG may be reflected on the logical display region 18eL or the physical display region 18eP by a processing similar to the case of reflecting the processing contents in the logical display region 18eL on the physical display region 18eP or the geometrical display region 18eG.
For example, referring to
(a) The arrangement information of IC1 is deleted from the arrangement information (refer to (a) of
(b) IC1 is deleted from the part information (refer to (b) of
(c) The connection information of IC1 is deleted from the connection information (refer to (c) of
(d) By reflecting the arrangement information, the part information and the connection information, from which IC1 was deleted, on the logical display region 18eL and the physical display region 18eP, IC1 and the connection information of IC1 are deleted from the logical display region 18eL and the physical display region 18eP (refer to (d) of
As a result, changed contents of arrangement/wiring in the physical display region 18eP is reflected on the logical display region 18eL and the physical display region 18eP and the contents are synchronized.
(4) In the above-described embodiment, description was made mainly for the case of displaying the three display regions of the logical display region 18eL, the physical display region 18eP and the geometrical display region 18eG on the display screen of the display unit 18e of the client system 18 being a terminal.
However, it goes without saying that the present invention is not limited to this, and any two display regions out of the logical display region 18eL, the physical display region 18eP and the geometrical display region 18eG may be selectively displayed on the display screen of the display unit 18e of the terminal.
Specifically, the two display regions of the logical display region 18eL and the physical display region 18eP may be displayed, the two display regions of the logical display region 18eL and the geometrical display region 18eG may be displayed, or the two display regions of the physical display region 18eP and the geometrical display region 18eG may be displayed.
Further, instruction of selecting a display region to be displayed may be performed by operating the keyboard 18f, the mouse 18g or the like of the client system 18.
Meanwhile, in the case of displaying any two display regions out of the logical display region 18eL, the physical display region 18eP and the geometrical display region 18eG, it is different only on the point where two display regions are displayed on the display screen of the display unit 18e of a terminal, and the other processings are the same as the above-described embodiment.
(5) In the above-described embodiment, outputting of various design information regarding electric design by using the client system 18 being a terminal is also made possible.
Specifically, the client system 18 selects and outputs only necessary information regarding electric design from a circuit diagram by the unit of logical (functional) block unit, a substrate unit or the like, and information can be produced. It is to be noted that the information to be outputted denotes various design information regarding electric design of a circuit diagram, a parts list, a netlist or the like.

Next, the information stored in the random access memory 18c is outputted to the display unit 18e, function block names are displayed in a tree view on the display screen of the display unit 18e based on the information stored in the random access memory 18c (step S4310), parts classified in a function block displayed on the top portion of the above-described tree view are displayed in a list by the part name unit, and the number of each part, a subtotal amount and a total amount are displayed (step S4312).

First, when this processing routine is activated by the input of a predetermined command or the like in the client system 18, the data A is dragged to the circuit block X and dropped on the display screen of the display unit 18e by using the mouse 18g (step S4602). More specifically, the data A and the circuit block X are selected as design information to be associated, and an operation for associating the data A with the circuit block X is performed by drag and drop using the mouse 18g (refer to “drag PDF to associate” in
Next, entity data showing the data A is stored in the random access memory 18c (step S4604), the fact that the data A is the associated data of the circuit block X is transmitted to the database and stored in the database (step S4604).
Next, an icon meaning that an associated data exists is displayed on the display region of the circuit block X on the display screen of the display unit 18e (step S4608).
Next, when the circuit block X is clicked by using the mouse 18g (step S4610), the associated data of the circuit block X is searched from the database and displayed in a list (step S4612) (refer to “Click a circuit block to display associated information in a list” in
Then, when the data A is clicked from the list of associated data by using the mouse 18g (step S4614) (refer to “Click data that needs to be displayed from the list of related information” in
Now, in the processing in associating the design information, design information to be outputted in the output processing of various design information in the above-described (5) may be selected as the design information to be associated.
(7) The above-described embodiments and the modification examples shown in (1) to (6) may be appropriately combined.
The present invention can be utilized in designing various products.
