Politecnico di Torino Porto Institutional Repository [ Proceeding ] A Fault Injection Environment for Microprocessor - based Board

Evaluating the faulty behavior of loiv-cost microprocessor-based boards is an increasingly important issue, due to their usage in nun2 safety critical systems. To address this issue. the paper describes a Software-implemented Fault Injection system based on the trace exception mode available in most microprocessors. The architecture of the complete Fault Injection environment is proposed, integrating modules for generating a fault list, for performing their injection and for gathering the results, respectively. Datu gathered from some sample benchmark applications are presented. The main advantages of the approach are low cost, good portabili5, and high efficiency.
