Abstract

A testing system includes a computer, a testing circuit board, and a motherboard. The testing circuit board includes a programmable logic device connected to the computer. The programmable logic device includes a predetermined signal. The programmable logic device is used to output an excitation signal to the motherboard. The motherboard is used to generate a back signal according to the excitation signal. The programmable logic device is used to analyze whether the back signal is consistent with the predetermined signal. The computer is used to display a testing result output by the programmable logic device. The disclosure further offers a testing method.

Description

technical field [0001] The invention relates to a main board testing system and method. Background technique [0002] In the process of functional verification and signal testing of the motherboard of a computer or server, it is often necessary to generate a special stimulus to verify the correctness and accuracy of the function. The traditional test method is to build a corresponding test environment to generate corresponding incentives for the main board, and then judge whether the operation of the main board is normal after being stimulated. However, the traditional testing methods are not highly automated and the testing efficiency is low. Contents of the invention [0003] In view of the above, it is necessary to provide a motherboard testing system and method with a high degree of automation. [0004] A main board testing system, comprising a test circuit board connected to the main board to be tested and a computer connected to the test circuit board, the test cir...
