Symbolic Execution based Verification of Compliance with the ISO 26262 Functional Safety Standard

This paper proposes a new technique for verifying the compliance of AUTOSAR software with the ISO26262 functional safety standard. A framework is presented which formally verifies that a given implemented AUTOSAR software fulfils high risk Automotive Safety Integrity Level (ASIL) C and D requirements. The framework exploits the power of symbolic execution to uncover defects early in the design stage. The efficacy of the framework is demonstrated on the AUTOSAR watchdog manager and watchdog interface modules.
