摘要
本文基于Synopsys公司的静态时序分析软件PrimeTime(PT),介绍了ASIC设计验证的静态时序分析(STA)方法。文中首先介绍了STA的基本原理,PT启动文件的设置和工作条件的选择,最后通过视频解码系统中帧间预测模块设计,阐明了静态时序的具体分析方法及PT的工作流程,并给出模块的静态时序分析报告并由此说明PT工具的有高时序路径分析覆盖率以及帧间预测模块的时序路径满足设计要求。
In this paper, based on static timing analysis software PrimeTime of Synopsys Company, the static timing analysis method （STA） for AS1C design verification is introduced. Firstly, the basic principles of STA, PT start-up file establishment and working condition choice are introduced. Then the inter-prediction module of video decoding system is used to explicate STA analysis method and PT workflow. The static timing analysis report is also given. The report shows that PT tool has high coverage fraction of timing path analysis,and the timing path satisfy the design requirements.
