A high-speed serial signal channel simulation innovation method before layout

Abstract

The invention provides a high-speed serial signal channel simulation innovation method before layout, which is characterized by comprising the following steps: (1) quickly modeling according to an embedded template; (2) establishing a crosstalk relationship of channels between the models; (3) instantiating the model, and establishing a channel connection relationship; (4) setting high-speed serial signal channel simulation parameters; (5) simulating; (6) displaying result data and pictures; and (7) automatically outputting a report. The invention has the advantages of visualization, easy operation, high efficiency, time domain and frequency domain integration automatic simulation, and effectively solves the problems of many steps, easy error, non-visual crosstalk association, incapability of time domain and frequency domain integration simulation, incapability of directly outputting reports, time and labor waste, difficulty in maintenance and the like in the process of the traditional method.

Description

technical field [0001] The invention belongs to the field of electronic design automation, and specifically relates to an innovative method for emulating high-speed serial signal channels before layout. Background technique [0002] Traditional high-speed serial signal channel simulation before layout requires manual model building and manual extraction of channels one by one. In the process of channel extraction, the influence of coupling points between channels on simulation results must be considered artificially; time domain, The frequency domain can only be set up for simulation alone, and the standard can only be added after the simulation. The final results cannot be automatically output, and the simulation results need to be pasted into the text editing software one by one. [0003] In this process, using the traditional method, there are many steps, the process is cumbersome, it requires a lot of manpower, and it is easy to make mistakes (the isolation of each chann...
