Abstract

In this paper we present a new modeling formalism that is well suited for modeling real-time systems in different application areas and on various levels of abstraction. These I/O-interval structures extend interval structures by a new communication method, where input sensitive transitions are introduced. The transitions can be labeled time intervals as well as with communication variables. For interval structures, efficient model checking techniques based on MTBDDs exist. Thus, after composing networks of I/O-interval structures, efficient model checking of interval structures is applicable. The usefulness of the new approach is demonstrated by various real-world case studies, including experimental results.
