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.

CHARME 2005 was sponsored by the IFIP TC10/WG10.5 Working Group on Design and Engineering of Electronic Systems and its Special Interest Group SIG- CHARME. It was organized by the Computer Science Department of Saarland University. Thisyear, twokindsofcontributionsweresolicited: (i)fullpapers, describingor- inalresearchwork, intendedforanoralplenarypresentation, (ii)shortpapers, descr- ingongoinglessmatureresearchworkintendedforpresentationaspostersorresearch prototypedemonstrations. Two very long sessions were allocated to poster and int- active presentations, with the aim of giving an emphasis on the working aspect of the working conference, where discussion of new or un?nished results and feedback are an essential aspect of the event.The community was extremely responsiveto this viewpoint: we received a total number of 79 submitted papers, out of which 21 long contributionsand 18 short contributionswere accepted for presentationat the conf- enceandinclusioninthisvolume.Allpapersreceivedaminimumofthreereviews.
