QPI signal optimization method and device, terminal and storage medium

Abstract

Embodiments of the present application provide a QPI signal optimization method and device, a terminal, and a storage medium, the method comprising: modifying a filter boost test default value of a signal equalizer according to an insertion loss value of a motherboard; modifying the equalization start default value and the equalization stop default value of the signal equalizer according to the ctlep value of the QPI boundary test; running a signal equalizer and leading the output value of the signal equalizer into a basic input and output system through a port converter; generating a signal eye diagram from the boundary test of the QPI signal, and obtaining an optimized result of the QPI signal according to the signal eye diagram. The invention can automatically optimize the detection andprocessing of the QPI signal, thereby greatly saving the processing time of the QPI signal.

Description

technical field [0001] The invention belongs to the technical field of server testing, and in particular relates to a QPI signal optimization method, device, terminal and storage medium. Background technique [0002] In today's server products, the quality indicators of high-speed and low-speed signals such as QPI (Quick Path Interconnect), DMI, etc. Efficiency, more and more widely used in server products. The QPI high-speed interconnection method enables the peak bandwidth between CPUs to reach 96GB / s. Even with the earliest QPI standard, its transmission speed reaches 6.4GT / s, which can meet the data transmission requirements between CPUs, CPUs and chips in the future. . The QPI bus architecture has reliability and performance. [0003] Based on the importance of QPI, the detection and setting of the QPI signal are also particularly important. The optimization and detection of QPI is done through Scanworks (boundary scan test platform). The first step is to set TXEQ&C...

AI Technical Summary

Problems solved by technology

The optimization and detection of QPI is done through Scanworks (boundary scan test platform). The first step is to set TXEQ&CTLE. If it is set according to the default value of the industry standard, there will be a Fail situation in the server product that runs for more than 20 hours, so there is no way to continue. In addition, even if Pass, it takes about 50 hours, which is a waste of time, especially for four-way products.
