Zusammenfassung
We present a general framework to support the compositional verification of timed systems using the interactive theorem prover PVS. The framework is based on timed traces that are an abstraction of the timed semantics of flat UML state machines. We define a compositional proof rule for parallel composition and prove its soundness in PVS. After composition, a hiding rule can be applied to hide internal events. The general theories have been applied to parts of the Medium Altitude Reconnaissance System (MARS) as deployed in the F-16 aircraft of the Royal Netherlands Air-Force.
