The increased complexity of embedded systems coupled with quick
design cycles to accommodate faster time-to-market requires
increased system design productivity that involves both model-based
design and tool-supported methodologies.
Formal methods are mathematically-based techniques and provide a
clean framework in which to express requirements and models of the
systems, taking into account discrete, stochastic and continuous
(timed or hybrid) parameters with increasingly efficient tools.
This book deals with these formal methods applied to
communicating embedded systems by presenting the related industrial
challenges and the issues of modeling, model-checking, diagnosis
and control synthesis, and by describing the main associated
automated tools.
