Model driven engineering for embedded real-time systems

International audienceIn order to keep competition at bay, industries have no other choice than ever increasing the innovative part in their products at a lower cost and within a shorter time-to-market. Obviously, this tends to make products drastically more and more complex and hard to realize. The Accord|UML research project, driven for several years by the CEA-List, aims to provide solutions to manage complexity in the development of real-time embedded systems (RTES). Accord|UML consists in a methodology and a set of dedicated tools. The methodology is based on a generative model-centered process that covers the whole RTES development cycle from the very early requirement analysis steps to the generation of an executable prototype. This paper will analyze how model driven engineering may be valued in a RTES development context. Especially, referring to the Accord|UML project, it will illustrate abstraction and refinement through the presentation of minimal language extensions for real-time concerns, code generation and validation of embedded real-time features
