Description

Technical Field

[0001] The present invention relates to the field of server design, and in particular to a server data signal automatic adjustment system and method. Background Art

[0002] When designing server products, there are more and more data link signals, and the requirements for signal integrity are also more stringent. Data link signals will inevitably cause loss in the data link during transmission, especially when the data link routing is too long, the loss of link signals is more obvious. Due to poor signal quality, signal distortion may even occur, and the signal driver cannot identify the signal, resulting in packet loss, affecting the normal use of the equipment mounted on the data link.

[0003] In order to avoid signal distortion caused by link signal loss during data link communication, the prior art generally configures a signal repeater ReDriver in a longer data link to compensate for the loss. ReDriver generally cooperates with a high-pass filter set at the receiving Rx end and a driver set at the transmitting Tx end to achieve compensation for link loss, so that the signal attenuation on the data link is smaller. The parameters of ReDriver are generally determined according to the designed data link configuration. Specifically, in the constructed test environment, it is necessary to manually adjust the ReDriver parameters for multiple data link tests and verifications, and the parameters that achieve the optimal data link signal during the test are taken as the parameters of ReDriver. When the server leaves the factory, the determined parameters are written into the ReDriver chip. For different data link designs, corresponding tests need to be performed each time, and the test workload is large. And the existing method cannot automatically adjust the ReDriver parameters according to the hardware situation. With the use of various data links, hardware configuration changes caused by the aging of boards, cables, etc. are inevitable. Therefore, the ReDriver parameters determined when the data link is in good condition will eventually fail due to the hardware configuration changes caused by aging. Summary of the invention
