Research On Graphical Verification And SI Analysis With PCB Data

Graphical verification based on PCB data and signal integrity simulating automatization are mainly discussed in the paper.For the reality that different design data are not compatible with each other, a method for graphical verification oriented heterogeneous EDA data structured design and homogenization techniques is put forward and realized after analyzing the defect of EDA tools available. The method is based on the data structure of graphical verification. Users can check directly through graphical interfaces according to self-defined rules and save the resulting data in the form specified.At present, Only a single net can be simulated once in cadence, therefore a new scheme was presented and realized in the paper. Through this method raised in this paper, more than one nets can be simulated at once, and the report can be built according to users requirement, the realtime log can be produced .The validity and utility of the software was validated through testing.
