Forum on specification & Design Languages (FDL) is a well established international forum devoted to dissemination of research results, practical experiences and new ideas in the application of specification, design and verification languages to the design, modelling and verification of integrated circuits, complex hardware/software embedded systems, and mixed-technology systems. Modelling and specification concepts push the development of new design and verification methodologies to system level thus providing a means for model-driven design of complex information processing systems in a variety of application domains. One of the principal advantages of FDL is that it brings together four related thematic areas and gives an opportunity to gain up-to-date knowledge in many broad areas of the fast evolving field of system design and verification. FDL 2013 will be held in Paris, France, September 24-26 and will be the sixteenth FDL conference following a series of highly successful events that took place in Lausanne, Lyon, Tübingen, Marseille, Frankfurt am Main, Lille, Darmstadt, Barcelona, Stuttgart, Sophia Antipolis, Southampton, Oldenburg, and Vienna.
