Complexity and criticality of automotive electronic embedded systems is steadily increasing today. A new standard —ISO 26262— recommends methods and techniques, such as fault injection, to improve safety. A first goal is to use fault injection earlier at the design stage, particularly on models providing an appropriate level of abstraction, to identify errors in the handling of safety requirements. A second objective is to use the results of these model-based analyzes to efficiently identify targets and check their implementation by fault injection. Hence, a verification approach, based on fault injection, has to be defined to complement conventional testing methods and analyzes traditionally used in automotive development process. The paper discusses the various steps of this approach, the link between abstraction and implementation, and gives a brief illustration on a real automotive application.
