Timing Simulation of Multi-Core Systems Based on AUTOSAR Models




With growing success, AUTOSAR has been established as the de facto industry standard for the development of automotive E/E architectures. Furthermore, the use of timing simulation for the evaluation of a system's behavior, especially with the introduction of multi-core systems, gets increasingly popular. Consequently, the question arises: Can all information, needed for a conclusive timing analysis, be obtained from an AUTOSAR model or are there crucial pieces missing?

The automotive industry is facing increasing demands for more sophisticated functions, e.g. comfort features, increasing safety requirements or the "internet of things" in smart electronic devices. To handle this demand, more than 100 million lines of code are mapped to many ECUs (Electronic Control Units), which can number up to about 100 units for high-end cars [1]. This number of ECU leads to an ever increasing complexity resulting in greater engineering effort, additional weight and restricted flexibility for updates and modifications....
