Component-Based Vehicular Distributed Embedded Systems : End-to-end Timing Models Extraction at Various Abstraction Levels

• In order to perform the end-to-end response-time and delay analyses of a system, its end-to-end timing model should be available. The majority of existing model- and component-based development approaches for vehicular distributed embedded systems extract the end-to-end timing model at an abstraction level and development phase that is close to the system implementation. We present a method to extract the end-to-end timing models from the systems at a higher abstraction level. At the higher level, the method extracts timing information from system models that are developed with EAST-ADL and Timing Augmented Description Language (TADL2) using the TIMMO methodology. At the lower level, the method exploits the Rubus component model to extract the timing information that cannot be clearly specified at the higher level such as trigger paths in distributed chains. We also discuss challenges and issues faced during extraction of the timing models. Further, we present guidelines and solutions to address these challenges.
