Abstract

The invention provides an integrated simulation method and a system based on an IBIS model, comprising the following steps: S1, collecting a required IBIS simulation model according to a project scheme; 2, placing a folder location and a specific port accord to that chip model to edit a configuration file; S3, defining the required parameters in the configuration file; 4, write a main program andcalling that correspond model; S5, running the simulation program and obtaining the simulation result. The invention avoids making a large number of modifications to the main program when the simulation model needs to be replaced, and defines the required parameters in the configuration file, thereby greatly reducing the bloat of the main program and requiring only direct calling. The invention solves the problems of low efficiency and error-prone caused by building simulation models one by one in the prior art, realizes the effective promotion of simulation efficiency, the promotion of program readability, and the shortening of product development cycle.

Description

technical field [0001] The invention relates to the technical field of signal simulation, in particular to an integrated simulation method and system based on an IBIS model. Background technique [0002] With the extensive development of cloud computing and big data, the server architecture is becoming more and more complex, and the customized solutions for end customers are getting more and more in-depth. While the signal rate continues to increase, the low-speed signal interconnection methods between devices are also becoming more and more complicated. The design rules are no longer enough to guarantee the signal quality, especially for complex topologies, the length of the trace cannot be simply used as the design rule, and many signal problems have occurred in the late design of the rules. The IBIS model is a fast and accurate modeling method for I / O buffers based on V / I curves. It is an international standard that reflects the electrical characteristics of chip drivers ...
