Model-Based Engineering of Embedded Real-Time Systems

This volume describes novel and state-of-the-art approaches to solvingproblems arising in the domain of embedded real-time systems. It isbased on the GI-Dagstuhl research seminar MBEERTS (Modelling-BasedEngineering of Embedded Real-Time Systems), which took place fromNovember 4th to 9th in 2007, at Schloss Dagstuhl, Germany.Using models throughout the development bears several advantages. Notonly can they be used as a tool for abstraction but also forverification, implementation, testing and maintenance. Due to thespecific domain of real-time systems several constraints like real-timerequirements, resource limitations or hardware-specific dependenciesarise and impede the acceptance of high-level models for theaforementioned purposes. The approaches presented in this volume tackle those problems and leadthe way to a greater acceptance and applicability of high-level modelsfor embedded real-time systems. Therefore this volume contains 10 longerchapters covering broad areas and 11 short chapters discussing severalspecific state-of-the-art tools used for model-based engineering ofembedded real time systems. The topic of 'Model-based Engineering of Real-time Embedded Systems'brings together a challenging problem domain (real-time embeddedsystems) and a solution domain (model-based engineering). Today,real-time embedded software plays a crucial role in most advancedtechnical systems such as airplanes, mobile phones, and cars, and hasbecome the main driver and facilitator for innovation. Development,evolution, verification, configuration, and maintenance of embedded anddistributed software nowadays are often serious challenges as drasticincreases in complexity can be observed in practice. This volume is a collection of 10 long and 11 short papers that surveythe state-of-the-art in model-based development of real-time embeddedsystems. It is composed of longer chapters that cover broad areas andshort papers that discuss specific tools. This state-of-the-art survey - outcome of a Dagstuhl Seminar held inDagstuhl Castle in November 2007 - covers the essential aspects ofintegrated software and systems engineering in the field of model-basedengineering of embedded real-time systems. The topics covered include:frameworks and methods, validation, model-based integration technology,formal modeling of semantics, fault management, concurrency models andmodels of computation, requirements modeling, formal derivation ofdesigns from requirements, test modeling and model-based testgeneration, quality assurance, design management, abstractions andextensions, and development techniques and problems of applicationdomains.
