Analyzing real-time systems

Abstract
Temporal logic model checking is a technique for the auto- matic verification of systems against specifications. Besides the correctness of safety and liveness properties it is often important to determine critical answer and delay times of systems, especially if they are embedded in a real-time envi- ronment. In this paper we present an approach which allows the verification as well as the timing analysis of real- time systems. The systems are described as networks of communicating time-extended finite state machines (I/O- interval structures). We use a compact symbolic representa- tion to obtain efficient analysis algorithms. 1
