FINaL: Driving High-Level Fault Injection Campaigns with Natural Language

Abstract

For integrated circuits in vehicular systems, ISO 26262 requires fault injection. Failure modes in natural language specify potential malfunctions of components in an abstract system model. Fault injection in system models ensures that safety mechanisms are effective. This causes a gap in the design process as fault injection campaigns must be derived manually.We introduce the framework FINaL that drives high-level Fault Injection campaigns with Natural Language. FINaL starts from an abstract system model in SysML, requirements, and failure modes described in natural language. We explain how FINaL automatically derives the parameters required for fault injection campaigns on virtual prototypes in SystemC. After training on a simple reference design, experimental results demonstrate that 20% up to 67% of the failure modes for a productive design can automatically be handled.
