使用参数时间自动机形式化Time4sys
Formalizing Time4sys using parametric timed automata
摘要:
关键的实时系统必须经过验证,以避免在出现故障时造成严重后果的风险。泰利斯开发了一个开放的形式主义Time4sys模型实时系统,具有表达功能,如周期性或零星的任务,任务依赖性,分布式系统等,但是,Time4sys不允许原生的正式推理。在这项工作中,我们提出了一个翻译从Time4sys(参数)时间自动机,以便允许一个形式化验证。
英文摘要:
Critical real-time systems must be verified to avoid the risk of dramatic consequences in case of failure. Thales developed an open formalism Time4sys to model real-time systems, with expressive features such as periodic or sporadic tasks, task dependencies, distributed systems, etc. However, Time4sys does not natively allow for a formal reasoning. In this work, we present a translation from Time4sys to (parametric) timed automata, so as to allow for a formal verification.
