This paper presents the SCADE System™ product line for systems modeling and generation based on the SysML standard and the Eclipse Papyrus open source technology. SCADE System has been developed in the framework of Listerel, a joint laboratory of Esterel Technologies, provider of the SCADE® tools, and CEA LIST, project leader of the Eclipse component, Papyrus. From an architecture point of view, the Esterel SCADE tools are built on top of the SCADE platform which includes both SCADE Suite®, a model-based development environment dedicated to critical software, and SCADE System enabling model-based system engineering. SCADE System includes Papyrus, an open source component (under EPL license), integrated in the modeling platform of Eclipse. Using this integrated modeling platform, both system and software teams share the same environment for system development. Furthermore, other model-based tools can be added to the environment, due to the use of Eclipse.

Modern automotive embedded systems are characterized by timing constraints at different levels in the design hierarchy and flow. System-level functions like modern active-safety functions are characterized by end-to-end constraints that span several ECUs and buses. ECU-level functions, like fuel injection controls need to cope with stringent resource requirements, tight time constraints and event-driven computations with different execution modes. This paper introduces some of the models, the techniques and the tool integration methods developed in the context of the INTERESTED project to guarantee timing correctness at all levels in the flow. In addition, we outline the issues arising from the application of these techniques to a fuel injection case study.

Clear and comprehensive view on an automotive system design, as well as its analysis/optimization, are the key research topics in the automotive domain. To tackle the first problem, modeling languages such as the EAST-ADL2 or the AUTOSAR metamodel, have been defined. The second issue has found its solution in the numerous analysis and optimization techniques. Nevertheless consideration of these two problems simultaneously is not the case. This has resulted in many tools that deal either with modeling or analysis and optimization. As a consequence it is difficult to embed these tools in the standard methodologies such as the EAST-ADL2/ AUTOSAR methodology. This especially applies to the higher abstraction layers as those defined by the EAST-ADL2. It is a consequence of a high dependability of analysis/optimization tools on the platform specific information.
