Abstract

The invention discloses a detection method and system for the rapid PCIE3.0 signal integrity. The detection method includes the following steps that a test platform with the waveform detection function is built; a test fixture is inserted into a detected PCIE slot, and two pieces of PCIE 3.0 waveform data are grasped through the test platform; the obtained two pieces of PCIE 3.0 waveform data are test and analyzed, and test result data is obtained; judgment is carried out according to the test result data, and if the test result is Pass, a test is passed; if the result is Fail, the test result data is analyzed, failure processing is carried out, and then the test is carried out again till the test is passed. According to the detection method and system, the PCIE industry standard serves as the basis, the electrical characteristic standard of a TX signal of a PCIE controller end is clear, and comprises parameters such as the transmission rate, jittering, the eye height and the eye width of the signal, so that the PCIE signal output quality of a server main board is guaranteed, and the whole operating performance of the server is improved.

Description

technical field [0001] The invention relates to a performance verification method of a data interface, which belongs to the technical field of computers, in particular to a fast PCIE 3.0 signal integrity detection method and system. Background technique [0002] In order to meet high scalability, PCIE has become an indispensable expansion interface on existing server equipment. Usually, some PCIE interface RAID cards, SAS cards, HBA cards and other devices are plugged in to meet different customer needs. As the demand for data transmission rate continues to increase, the mode and transmission rate of the PCIE interface have also developed to the PCIE3.0 specification. Similarly, the PCIE3.0 signal quality directly affects the function and performance of these external cards. PCIE3.0 devices can work stably and efficiently. The signal quality of PCIE3.0 must conform to the PCIE protocol specification. Therefore, for the PCIE3.0 interface, the integrity risk of its own signal ...
