Problems solved by technology

With the increase of business volume, there are more and more signal links for internal signal quality evaluation of the server, and the server design cycle is getting shorter and shorter. Relying on the existing method of first analyzing the link and then performing simulation evaluation based on the analysis results mode, the task load is large and complicated, and it can no longer meet the needs of current signal quality evaluation

Abstract

The invention discloses a signal link signal quality evaluation method. The method comprises the following steps: obtaining a target signal link to be evaluated; searching for the sender model, transmission line model, via model and receiver model matched with the target signal link in the preset model library; the transmitter model, the transmission line model, the via model and the receiver model are connected to obtain the simulation link. The signal simulation parameters and transmission line length corresponding to the target signal link are inputted into the simulation link to obtain thetarget simulation link. By using the target simulation link, the signal quality evaluation results corresponding to the target signal link are obtained. It can complete the signal quality evaluationof the target signal link, further shorten the design cycle of the circuit board, and improve the signal quality of the circuit board design. The invention also discloses a signal link signal qualityevaluation device, a device and a readable storage medium, which have corresponding technical effects.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a signal link signal quality evaluation method, device, equipment and a readable storage medium. Background technique [0002] The design of the server is mainly divided into two parts, signal design and power supply design. Among them, the power supply design is the basis of the entire server design, and all chips need a stable power supply to work normally. Signal design is the soul of server design. The realization of various functions needs to be controlled by signals. The quality of signal design is related to the realization and stability of various functions of the circuit board. [0003] At present, to evaluate the signal quality of a signal link, it is necessary to analyze the signal transmission performance of each part of the signal link to be evaluated, such as the transmitting end chip, transmission line, via, and receiving chip. Then, the performance...
