Model-Based Analysis and Engineering of Automotive Architectures with EAST-ADL

International audienceModern cars have turned into complex high-technology products, subject to strict safety and timing requirements , in a short time span. This evolution has translated into development processes that are not as efficient, flexible and agile as they could or should be. This paper presents the main aspects and capabilities of a rich model-based design framework, founded on EAST-ADL. EAST-ADL is an architecture description language specific to the automotive domain and complemented by a methodology compliant with the functional safety standard for the automotive domain ISO26262. The language and the methodology are used to develop an information model in the sense of a conceptual model, providing the engineer the basis for specifying the various aspects of the system. Inconsistencies, redundancies, and partly even missing system description aspects can be found automaticlally by advanced analyses and optimization capabilities to effectively improve development processes of modern cars
