1. Field of the Invention
The present invention relates to a method for detecting and transmitting the error messages, and more particularly to a method for detecting and transmitting the error messages by using a software module.
2. Description of Related Art
During the circuit board design or fabrication phase, an external trace is welded on the chip or a fixture is used to test and determine whether for any error in the data transmission or whether the chip operates normally.
The embedded controller 150 receives an instruction from the input device 140, for example an instruction to activate the embedded controller 150 to transmit the data or an instruction to be transmitted to other component via embedded controller 150. After the instruction is received and executed by the embedded controller 150, an instruction is sent to the BIOS 170 to trigger the BIOS 170 to transmit the data requested by the instruction to the embedded controller 150, wherein the data, for example, comprises the procedure and results of the error test performed by the BIOS 170. Finally, the embedded controller 150 transmits the data to the fixture 180 and then displayed on the remote module 130.
However, some fixtures are very expensive, and the fabrication process of the fixture is quite complicated, thus it is common limited fixtures are used and shared by multiple engineers, and the fixtures get easily damaged due high frequency of usage. For example, to test the mother board, the fixture must be soldered to the mother board, and the completion of the testing, the solder has to be removed. Furthermore, in a case when the fixture is shared by multiple engineers, the testing efficiency is significantly affected.
Therefore, it is an object of the present invention to provide a method for detecting and transmitting the error messages using a software module instead of using the fixture, so as to reduce the testing time and cost.
According to an aspect of the present invention a controller inside the local module is adopted for performing an error test to obtain a test result. Next, the controller is adopted for transmitting the test result to an application software in the local module. Finally, the application software is adopted for transmitting the test result to the remote module via a transmission interface.
According to an embodiment of the present invention, an instruction is provided by the input device and the controller executes the instruction to obtain a corresponding result. Next, and the controller transmits the result to the application software. Finally, the application software transmits the result to the I/O (Input/Output) device of the local module or transmits the result to the remote module via the transmission interface.
According to an embodiment of the present invention, the remote module provides an instruction to the application software, and the application software transmits this instruction to a controller. Thereafter, the controller executes the instruction to obtain a corresponding result. Next, the controller transmits the result to the application software. Finally, the application software transmits the result to the I/O (Input/Output) device of the local module or transmits the result to the remote module via the transmission interface.
Thus, the present invention utilizes the software module to detect and transmit the error messages instead of fixture, and therefore the disadvantages due to the use of fixture can be effectively avoided. In addition, the exact location where the error occurs during the data transmission and its detail on the circuit board can be detected by the remote module or the I/O device.
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention, and together with the description, serve to explain the principles of the invention.
The local module 210 may be comprised of a computer system and the input device 240 may be comprised of a keyboard or a mouse. The OS 222 may be DOS (Disk Operating System), Windows 2000/XP, or any other operating systems. The controller 224 may be a CPU (Central Processing Unit), a south bridge chip or a north bridge chip. The I/O device 260 may be a touch screen. The transmission interface 225 may be a USB (Universal Serial Bus), an IEEE 1394 or a network transmission interface. The transmission interface 225 is electrically connected to the remote module 230, wherein the remote module 230 may be an oscilloscope, a computer or a display device. The OS 222 and the application software 221 are stored in a memory device on the circuit board, and the OS 222 may provide the basic transmission control (e.g. controlling the transmission interface and the application software).
For the purpose of illustrating of the present invention, a computer with a pre-installed OS is exemplified hereinafter. It will be apparent to one of the ordinary skills in the art that the present invention can also be applied in other circuit boards, thus the present invention is not limited to such hardware combination.
When the user uses the input device 240 to input an instruction to the computer system (the local module 210), the instruction is sent to the embedded controller 250. Wherein, the instruction may be either an instruction of activating the embedded controller 250 to transmit the error message to the hardware module 220 or an instruction to the BIOS 223.
If the instruction input by the user is intended to activate the embedded controller 250 to transmit the error message, the embedded controller 250 performs an error test procedure and transmits the test result to the hardware module 220. Then, this data is sent to the controller 224 in the hardware module 220. Afterwards, with the help of the OS 222, the application software 221 integrates the error test data and outputs the result either to the remote module 230 or to the I/O device 260.
If the instruction input by the user is intended to provide an instruction to the BIOS 223, the instruction is provided to the embedded controller 250 and then transmitted to the BIOS 223. Then, the BIOS 223 executes the instruction and performs the error test, and the procedure and results of the error test are transmitted to the controller 224 in the hardware module 220 or output to the embedded controller 250. Afterwards, with the help of the OS 222, the application software 221 integrates the error test data and outputs the result to the remote module 230 or the I/O device 260.
The application software 221 outputs the error test data in two different ways. If the error test data is output to the remote module 230 via the transmission interface 225, e.g. output to the oscilloscope connected to the USB, the error test data is then displayed on the oscilloscope. Alternatively, if the error test data is output from the I/O device 260, the error test data is displayed on the touch screen. The manner of outputting the error test data is determined by the embedded controller 250, the application software 222, or the instruction input by the user. However, it will be apparent to one of the ordinary skills in the art that other options are also within the scope of the present invention.
Hereinafter, a detail description of inputting the instruction from the input device in order to request the embedded controller to transmit the data is described in greater detail in the first embodiment of the present invention with reference to
