Abstract

The invention provides a high-speed link signal integrity fast evaluation method and system. The method comprises the following steps: S1, selecting a test-corrected similar type topology as a reference topology; S2, performing modeling and simulation respectively based on the current topology and the reference topology; S3, and analyzing and comparing the simulation results of the current topology and the reference topology. The invention solves the problem of poor timeliness for high-speed link signal integrity simulation evaluation in the prior art, realizes the simulation evaluation of thehigh-speed link in a relatively short time, maximizes the time for link design and optimization, and improves timeliness. The method makes full use of the accumulated data, can quickly evaluate the risk of similar link design, improves the efficiency of high-speed link evaluation, and buys more time for project design optimization.

Description

technical field [0001] The invention relates to the technical field of high-speed signals, in particular to a method and system for quickly evaluating high-speed link signal integrity. Background technique [0002] High-speed interconnect phenomena are often negligible in traditional digital system designs because their impact on system performance is minimal in traditional digital systems. However, with the continuous development of computer technology, high-speed interconnection is playing a leading role among many factors that determine system performance, which often leads to some unforeseen problems and greatly increases the complexity of system design. Therefore, in the design of high-speed links, it is necessary to optimize each module as much as possible, use simulation tools to evaluate the design feasibility and risk points in advance, and optimize the design based on the simulation results to improve the success rate of system design and shorten the development cy...
