This book is the latest contribution to the Chip Design Languages series and it consists of selected papers presented at the Forum on Specifications and Design Languages (FDL'06), in September 2006. The book represents the state-of-the-art in research and practice, and it identifies new research directions. It highlights the role of specification and modelling languages, and presents practical experiences with specification and modelling languages.

More than ever, FDL is the place for researchers, developers, industry designers, academia, and EDA tool companies to present and to learn about the latest scientific achievements, practical applications and users experiences in the domain of specification and design languages. FDL covers the modeling and design methods, and their latest supporting tools, for complex embedded systems, systems on chip, and heterogeneous systems. FDL 2009 is the twelfth in a series of events that were held all over Europe, in selected locations renowned for their Universities and Reseach Institutions as well as the importance of their industrial environment in Computer Science and Micro-electronics. In 2009, FDL was organized in the attractive south of France area of Sophia Antipolis. together with the DASIP (Design and Architectures for Signal and Image Processing) Conference and the SAME (Sophia Antipolis MicroElectronics ) Forum. All submitted papers were carefully reviewed to build a program with 27 full and 10 short contributions. From these, the Program Committee selected a shorter list, based on the evaluations of the reviewers, and the originality and relevance of the work that was presented at the Forum. The revised, and sometimes extended versions of these contributions constitute the chapters of this volume. Advances in Design Methods from Modeling Languages for Embedded Systems and SoC’s presents extensions to standard specification and description languages, as well as new language-based design techniques and methodologies to solve the challenges raised by mixed signal and multi-processor systems on a chip. It is intended as a reference for researchers and lecturers, as well as a state of the art milestone for designers and CAD developers.

The seventh book in the CHDL Series is composed of a selection of the best articles from the Forum on Specification and Design Languages (FDL'04). FDL is the European Forum to learn and exchange on new trends on the application of languages and models for the design of electronic and heterogeneous systems. The forum was structured around four workshops that are all represented in the book by outstanding articles: Analog and Mixed-Signal Systems, UML-based System Specification and Design, C/C++-Based System Design and Languages for Formal Specification and Verification. The Analog and Mixed-Signal Systems contributions bring some answers to the difficult problem of co-simulating discrete and continuous models of computation. The UML-based System Specification and Design chapters bring insight into how to use the Model Driven Engineering to design Systems-on-Chip. The C/C++-Based System Design articles mainly explore system level design with SystemC. The Languages for FormalSpecification and Verification is represented by an invited contribution on the use of temporal assertions for symbolic model checking and simulation. And finally chapter in this book contributed by preeminent members of the automotive design industry presents the recent industry standard AutoSAR. Overall Advances in Design and Specification Languages for SoCs is an excellent opportunity to catch up with the latest research developments in the field of languages for electronic and heterogeneous system design.

Until the late 1980s, information processing was associated with large mainframe computers and huge tape drives. During the 1990s, this trend shifted toward information processing with personal computers, or PCs. The trend toward miniaturization continues and in the future the majority of information processing systems will be small mobile computers, many of which will be embedded into larger products and interfaced to the physical environment. Hence, these kinds of systems are called embedded systems. Embedded systems together with their physical environment are called cyber-physical systems. Examples include systems such as transportation and fabrication equipment. It is expected that the total market volume of embedded systems will be significantly larger than that of traditional information processing systems such as PCs and mainframes. Embedded systems share a number of common characteristics. For example, they must be dependable, efficient, meet real-time constraints and require customized user interfaces (instead of generic keyboard and mouse interfaces). Therefore, it makes sense to consider common principles of embedded system design. Embedded System Design starts with an introduction into the area and a survey of specification models and languages for embedded and cyber-physical systems. It provides a brief overview of hardware devices used for such systems and presents the essentials of system software for embedded systems, like real-time operating systems. The book also discusses evaluation and validation techniques for embedded systems. Furthermore, the book presents an overview of techniques for mapping applications to execution platforms. Due to the importance of resource efficiency, the book also contains a selected set of optimization techniques for embedded systems, including special compilation techniques. The book closes with a brief survey on testing. Embedded System Design can be used as a text book for courses on embedded systems and as a source which provides pointers to relevant material in the area for PhD students and teachers. It assumes a basic knowledge of information processing hardware and software. Courseware related to this book is available at http://ls12-www.cs.tu-dortmund.de/~marwedel.

Embedded systems take over complex control and data processing tasks in diverse application ?elds such as automotive, avionics, consumer products, and telec- munications. They are the primary driver for improving overall system safety, ef?ciency, and comfort. The demand for further improvement in these aspects can only be satis?ed by designing embedded systems of increasing complexity, which in turn necessitates the development of new system design methodologies based on speci?cation, design, and veri?cation languages. The objective of the book at hand is to provide researchers and designers with an overview of current research trends, results, and application experiences in c- puter languages for embedded systems. The book builds upon the most relevant contributions to the 2008 conference Forum on Design Languages (FDL), the p- mier international conference specializing in this ?eld. These contributions have been selected based on the results of reviews provided by leading experts from - search and industry. In many cases, the authors have improved their original work by adding breadth, depth, or explanation.

As electronic technology reaches the point where complex systems can be integrated on a single chip, and higher degrees of performance can be achieved at lower costs, designers must devise new ways to undertake the laborious task of coping with the numerous, and non-trivial, problems that arise during the conception of such systems. On the other hand, shorter design cycles (so that electronic products can fit into shrinking market windows) put companies, and consequently designers, under pressure in a race to obtain reliable products in the minimum period of time. New methodologies, supported by automation and abstraction, have appeared which have been crucial in making it possible for system designers to take over the traditional electronic design process and embedded systems is one of the fields that these methodologies are mainly targeting. The inherent complexity of these systems, with hardware and software components that usually execute concurrently, and the very tight cost and performance constraints, make them specially suitable to introduce higher levels of abstraction and automation, so as to allow the designer to better tackle the many problems that appear during their design. Advanced Techniques for Embedded Systems Design and Test is a comprehensive book presenting recent developments in methodologies and tools for the specification, synthesis, verification, and test of embedded systems, characterized by the use of high-level languages as a road to productivity. Each specific part of the design process, from specification through to test, is looked at with a constant emphasis on behavioral methodologies. Advanced Techniques for Embedded Systems Design and Test is essential reading for all researchers in the design and test communities as well as system designers and CAD tools developers.
