The present disclosure relates to detection systems, and particularly, to a chip test system.
Many digital control chips are integrated in motherboards. For example, a digital control chip is used to supply power for a central processing unit (CPU) of a motherboard. In using the digital control chip, a computer is applied to burn a configuration file to the digital control chip. For different types of motherboards, the configuration files burned into the digital control chip mounted on the different types of motherboards are different, and it is difficult to determine whether the configuration file burned into the corresponding digital control chip is correct.
Many aspects of the present embodiments can be better understood with reference to the following drawing. The components in the drawing are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
The figure is a circuit diagram of an exemplary embodiment of a chip test system.
The disclosure, including the accompanying drawing in which like references indicate similar elements, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to the figure, an embodiment of a chip test system includes a digital control chip 10, a controller 20, and an indication circuit 30. A configuration file is burned into the digital control chip 10. The configuration file includes a first identification number. The controller 20 is connected to the indication circuit 30. In the embodiment, the digital control chip 10 is a digital pulse control chip. The digital control chip 10 includes a system management bus (SMBus) interface 12. The controller 20 is connected to the SMBus interface 12 through a data signal line SMBDAT and a clock signal line SMBCLK. The controller 20 is an integrated baseboard management controller (IBMC).
The indication circuit 30 includes a light emitting diode (LED) D1 and a resistor R1. A cathode of the LED D1 is connected to the controller 20. An anode of the LED D1 is connected to a power source P through the resistor R1.
In designing a motherboard, a computer is needed to debug a digital control chip mounted on the motherboard. After debugging the digital control chip, the computer generates a configuration file of the designed motherboard. A first identification number is written to the configuration file. Each type of motherboards will have a unique identification number.
Before determining whether the configuration file burned into the digital control chip 10 is correct, users identify the identification number of the motherboard, and controls the computer to write the identification number to the controller 20. The written identification number functions as a predetermined identification number for matching to the digital control chip. In testing, the controller 20 reads the first identification number of the configuration file burned into the digital control chip 10, and determines whether the read first identification number is the same as the predetermined identification number. If the read first identification number is the same as the predetermined identification number, the controller 20 outputs a logic 0 (low level) signal to the indication circuit 30. The LED D1 emits light, which indicates that the configuration file burned into the digital control chip 10 is correct is the correct file. If the read first identification number is different than the predetermined identification number, the controller 20 outputs a logic 1 (high level) signal to the indication circuit 30. The LED D1 fails to emit light, which indicates that the configuration file burned into the digital control chip 10 is not the correct file. Then the correct configuration file can be burned into the digital control chip 10.
Although numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
