... model certain class of real- time systems like a biphase mark protocol [31]. The Alur-Dill timed automata framework [1] is arguably the best known framework to model a real- time system, and is the ... exclusion algorithm. 1 Introduction In a typical real- time system, timing constraints on the system s behavior are used to ensure its correctness. Such a system is often modeled by using a set of timing ... parametric safety verification of real- time systems in which “correct orderings of events” needed for system correctness are maintained by timing constraints on the systems’ behavior. By using EOA,...
