摘　　要：静态时序分析方法不依赖于激励,且可以穷尽所有路径,运行速度很快,占用内存很少,克服了动态时序验证的缺陷。我们探讨了时序路径、路径延迟、时序约束等问题,重点研究了多周期路径造成的时序异常排除方法,并用静态时序分析工具Primetime对微控制器软核HGD08R01进行了案例分析,获得了满意的效果。Static timing analysis method has great predominance against dynamic timing verification method. It does not need stimuli, can search all the possible paths, has faster speed, and needs less resource. Some key issues about microcontroller were discussed including critical timing path, path delay and timing constraints. The method to exclude the timing exceptions on multi-cycle path was especially studied. A case study was taken on a in-house developed MCU. Experiment result showed great improvement in both run-time and resource cost.
