| 摘 要： | 针对潜在定时分析研究的现状,以及时间Petri网与潜在定时分析的共性,提出了基于时间Petri网的潜在定时分析方法。将Petri网模型分为五种基本模式,并分别定义了五种基本模式的变迁条件和变迁规则。通过Petri网的可达标识集与设计状态之间的关系找到潜在通路。两个实例的仿真分析结果与实际一致,证实了方法的有效性和正确性。

| Abstract: | Sneak timing is an important factor for the system safety. But, there are seldom effective techniques can discover sneak timing. To address this problem, the paper presented sneak timing analysis technique based on Time Petri Nets. Five basic Petri net patterns were proposed, and the transition condition and transition rules of each basic pattern were given. Two typical examples were used to demonstrate the approach. |
