Real-Time Relational Interface Behavior Modeling and Specification

In this paper we propose a formal model for real-time interfaces to support interface specification, composition and refinement with various features. We introduce a practical class of finitely representable interfaces with duration automata as their finite representation. With this sort of representation we can verify component-based systems in a compositional way, and the verification can be started at early stages of the development process for small pieces of the developed systems.
