AUTOSAR as specified in its current version fosters timing-constraints at application level to support the development of real-time automotive applications. However, the standard's actual specification does not consider any timing information for its basic software. In consequence, the over-all timing-behavior of software running at a specific system node can not be calculated and thus validated at development-time. Even worse, any exchange or modification of basic software modules induces unpredictable alteration in system timing, and may even lead to a severe miss of execution deadlines. Within this paper we solve this issue by using a component based basic software architecture, as much as timing-aware software composition for basic software components. We therefore introduce timing contracts as enhancement for existing interface contracts, specify a timing annotation language on a conceptual level, and demonstrate how to capitalize on our approach by calculating timings within composed basic software architectures at development time.
