This paper reports on the usage of a broad palette of formal modeling and analysis techniques on a regular industrial-size design of an ultra-modern satellite platform. These efforts were carried out in parallel with the conventional software development of the satellite platform. The model itself is expressed in a formalized dialect of AADL. Its formal(More)
We describe an approach to support UML-based development of embedded systems by formal techniques. A subset of UML is extended with timing annotations and given a formal semantics. UML models are translated, via XMI, to the input format of formal tools, to allow timed and non-timed model checking and interactive theorem proving. Moreover, the Play-Engine(More)
This paper shows on hand of a case study the usefulness of the UML profile with real-time defined in the Omega project and of the IF validation tool-set. The case study is about intricate timing aspects arising in a small but complex component of the airborne Medium Altitude Reconnaissance System produced by NLR 1. The purpose is to show how automata-based(More)
