Automated Testing for Automotive Embedded Systems

The automotive embedded system becomes even more complex and occupies more portion of vehicle price lately. Therefore, automotive industries apply a model-based approach for the embedded system development. The model-based approach improves quality and reduces cycle time by using modeling and its ability to simulate to introduce early validation of requirements. This paper describes automatic test generation and execution techniques for automotive embedded systems to maximize the early validation capabilities of model-based development process. The proposed techniques can cover from the functional high level model validation to the auto-generated software validation. For the functional model validation, a virtual prototype is used on the PC environment. A rapid prototype and target execution and monitoring system, Target Suite, is developed for the generated software validation. We also develop an automatic testing and analysis environment to manage the test executions and the corresponding results. The proposed model-based automated validation techniques would go far forward to improving the reliability and cost-effectiveness of the products
