Increasingly complex microcontroller designs for safety-relevant automotive systems require the adoption of new methods and tools to enable a cost-effective verification of their robustness. In particular, costs associated to the certification against the ISO26262 safety standard must be kept low for economical reasons. In this context, simulation-based verification using instruction set simulators (ISS) arises as a promising approach to partially cope with the increasing cost of the verification process as it allows taking design decisions in early design stages when modifications can be performed quickly and with low cost. However, it remains to be proven that verification in those stages provides accurate enough information to be used in the context of automotive microcontrollers. In this paper we analyze the existing correlation between fault injection experiments in an RTL microcontroller description and the information available at the ISS to enable accurate ISS-based fault injection.
