Applying Static Timing Analysis to Component Architectures

The increase in software functions and software complex-ity of automotive applications requires appropriate software architectures. A promising approach is the component ar-chitecture which also stands in the centre of the automotive standardisation project AUTOSAR[2]. As every embedded real-time system inevitably has upper time bounds, we present an integrated method of timing es-timation for highly flexible and variant applications based on a prototype component architecture. Therefore, we espe-cially develop methods for parameterised timing estimation which depend on the grade of complexity, variability and necessary exactness. The feasibility of the introduced concept is shown in the prototype architecture and a prototype application
