Book Description

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.
