Comparing system- and test model with integrated software-based signal simulation

Test automation in distributed systems requires new methods in signal simulation for the stimulation of the distributed system. Increasing complexity of electric electronic (E/E) systems enhances the testing-effort. The main challenge is reducing the time consuming manual stimulation in consideration of improving the quality of testing. Currently used systems for test automation with a software-based approach have to be adapted to each hardware and software version of the system to be tested. The approach represented shows a new approach through the integration of a simulation service in the AUTOSAR software architecture. By integrating a generic software-based simulation module with an interaction point at the basic software driver layer, the execution of tests can be automated and improved under consideration of adaptivity and reproducibility.
