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,...
