Problems solved by technology

In a server system, it may be necessary to support all kinds of PCI-E X16, PCI-E X8, PCI-E X4, etc. At this time, due to the limitation of the server chassis structure such as 1U\2U, it is difficult to expand different PCI-E devices. The emergence of PCI-E adapter card solves the above problems and realizes the expansion of different PCI-E devices. Since PCI-E external card equipment is very important to the server system, the design quality of the PCI-E adapter card is also required. To obtain a comprehensive guarantee, the functional integrity verification of the PCI-E riser card is an important test in the development of server boards. At present, there is no better way to verify the functional integrity of the PCI-E riser card.

The invention relates to the technical field of computer board card development and testing, in particular to a method for online testing the function integrity of a PCI-E riser card. By means of the method, rich information of a PCI-E device can be obtained, the functions of the PCI-E riser card can be comprehensively verified through the information, operation is easy, batch operation is facilitated, the purpose of verifying the function integrity of the PCI-E riser card is effectively achieved, and the quite high application value is achieved.

Description

technical field [0001] The invention relates to the technical field of development and testing of computer boards, in particular to a method for online testing of the functional integrity of a PCI-E adapter card. Background technique [0002] The development of various development and testing methods is accompanied by the development of computer technology. That is to say, since the birth of computer technology, people have been striving for a higher and more stable computer system. The process of this effort Including the development process of boards and cards at all levels, and testing methods, as an integral part of the development process, are also occupying an increasingly important position in the computer development process. In the past few decades, it can be said that the update of test methods has filled the gaps in development and testing. Every computer platform that runs stably has undergone verification of many test programs and test methods. Nowadays, the co...
