The growing complexity of embedded systems calls for modeling formalisms that can be simulated and analyzed to explore the space of design alternatives. This thesis describes the development of a modeling formalism and tools for design space exploration at early design stage.We extend the classical worst-case model checking for timed automata to stochastic analysis based on a refinement of temporal uncertainty intervals into delay distribution. On one hand we introduce the formalism of Duration Probabilistic Automata (DPA) supporting analysis as well as optimization. On the other hand we provide DESPEX (DEsign SPace EXplorer), a tool for performance evaluation of high-level models of applications running on multi-core platforms. We also sho...
