Matching scenarios with timing constraints

Networks of communicating finite-state machines equipped with local clocks generate timed MSCs. We consider the problem of checking whether these timed MSCs are ``consistent'' with those provided in a timed MSC specification. In general, the specification may be both positive and negative. The system should execute all positive scenarios ``sensibly''. On the other hand, negative scenarios rule out some behaviours as illegal. This is more complicated than the corresponding problem in the untimed case because even a single timed MSC specification implicitly describes an infinite family of timed scenarios. We outline an approach to solve this problem that can be automated using UPPAAL.
