Dynamic Timing Analysis and Its Application in Nanometer IC Design

文章讨论了动态时序分析算法及其在纳米级IC设计中的应用.首先,针对静态敏化算法存在的静态伪路径(StaticFalsePath)问题,提出了动态敏化算法,分析了静态敏化和动态敏化的关系.最后讨论了在电源噪声和串扰噪声影响下的动态时序分析.实验结果表明,串扰噪声条件下的动态时序分析结果比静态时序分析给出的保守结果准确得多.

This paper addresses dynamic timing analysis and its application in nanometer technology integrate circuits design. Firstly, dynamic sensitization is presented to deal with static false path in static timing analysis. The corre3ation between static sensitization and dynamic sensitization is discussed. Finally, its application in timing verification considering power noise and crosstalk noise is provided. Experiments show that dynamic timing analysis can present more accurate results than that of static timing analysis.
