Contributions on UML address the application of UML in the specification of embedded HW/SW systems. C-Based System Design embraces the modeling of operating systems, modeling with different models of computation, generation of test patterns, and experiences from case studies with System C. Analog and Mixed-Signal Systems covers rules for solving general modeling problems in VHDL-AMS, modeling of multi-nature systems, synthesis, and modeling of Mixed-Signal Systems with System C. Languages for formal methods are addressed by contributions on formal specification and refinement of hybrid, embedded and real-time stems. Together with articles on new languages such as System Verilog and Software Engineering in Automotive Systems the contributions selected for this book embrace all aspects of languages and models for specification, design, modeling and verification of systems. Therefore, the book gives an excellent overview of the actual state-of-the-art and the latest research results.
