From Safety Analyses to Experimental Validation of Automotive Embedded Systems

Abstract

Automotive embedded systems are becoming increasingly complex. Therefore verification activities are paramount to ensure safety. ISO 26262 is the first standard specifically dedicated to automotive safety systems. This standard requires introducing fault injection (FI) from the very early phases of the development process. Our work aims at developing an approach that will help integrate FI in the whole development process in a continuous way, from system requirements to the verification and validation phase. In this paper, we concentrate on exploring the benefits of safety analyses for experimental validation of the system. We propose an analogy between FI during the pre-implementation phase with safety analyses that are of common use during system design. We finally illustrate this approach on a case study from the automotive domain.
