With the rapid increase of design scale, SoC design is using more and more third party standard cells and IPs. Design house needs to select the libraries from multiple IP vendors, which requires to comprehensively evaluate these libraries from many aspects, such as accuracy, performance, power, area and so on. This paper introduces a fast static comparison analysis solution based on timing library data. It can do fast data statistics and analysis of two different vendor’s libraries and help to compare their difference. By using this solution, the library evaluation time is dramatically reduced from 1 week to 0.5 day.
