Validating the safety of embedded real-time control systems using FMEA

Traditional failure modes and effects analysis techniques have been adapted and extended to include assessment of software failures. The resulting technique is used to assess the safety of embedded real-time control systems designed for use in automotive applications. The use of FMEA techniques in assessing the software safety of those controllers has allowed analysis of the effects of a more comprehensive set of potential failures, including data corruption, than is practical using other software safety analysis techniques. The ability to assess the results of data corruption has proven to be crucial in providing feedback to design teams about the potential safety risks of the designs analyzed.<>
