The violation of real-time constraints in electronic control units leads to sporadic failures. Consequently, the real-time properties of an electronic control unit have to be inspected thoroughly. This necessitates an analysis of the maximum computational resources, that are required by the different software components of the electronic control unit.
The focus of this thesis is to develop new testing methods for determining the worst case execution times of automotive software components. Furthermore existing test concepts are extended such, that they are suitable for a practical application. Different applied methods for automatic test data generation try to find test cases, that cause a preferably long computation time. The testing methods are evaluated both by simulation and by examining complex software components that run on electronic control units.
