Embedded Systems: Design, Analysis and Verification
The objective of this work is the analysis and verification of distributed
real-time systems. Such systems have to work in a timely manner in order to deliver
the desired services. We consider a system architecture with multiple computation
resources. The aim is to work out a compositional state-based analysis technique to determine exact response times and to validate end-to-end deadlines.
Further, we consider such systems in a larger context, where a set of
systems work in a collaborative and distributed fashion.
A major aspect of such collaborative systems is
the dynamic evolution. New systems can participate,
existing systems may leave because of failures, or properties may change.
We use contracts to encapsulate systems which work in a collaborative manner. These contracts define sound
timing bounds on services offered to the environment. When some systems evolve, only those parts which changed need to be
