ISO 26262 metric depends on the fault classification of the hardware design (safe, residual fault, single point fault, multi point fault). Reaching the target ASIL for safety-critical systems requires accurate analysis and validation through fault injection. This session describes a case study and best practices to determine the fault classification during a fault injection campaign in an IP core. We will detail the methodology and tools used in a fault injection campaign, including:
• Steps in a fault campaign flow
• Input data required for fault injection
• Methodological approach for convergence
• Issues, challenges, and recommendations
