The Integration of On-Line Monitoring and Reconfiguration Functions using EDAA - European design and Automation Association1149.4 Into a Safety Critical Automotive Electronic Control Unit

This paper presents an innovative application of EDAA - European design and Automation Association 1149.4 and the Integrated Diagnostic Reconfiguration (IDR) as tools for the implementation of an embedded test solution for an Automotive Electronic Control Unit implemented as a fully integrated mixed signal system. The paper described how the test architecture can be used for fault avoidance with results from a hardware prototype presented. The paper concludes that fault avoidance can be integrated into mixed signal electronic systems to handle key failure modes.
