Out-of-Norm Assertions

Abstract— The increasing use of electronics in transport systems, such as the automotive and avionic domain, has lead to dramatic improvements with respect to functionality, safety, and cost. However, with this growth of electronics the likelihood of failures due to faults originating from electronic equipment also increases. Although permanent failure rates are constantly diminishing due to improvements in manufacturing, the downsizing of semiconductor features has lead to a significant increase in transient system disturbances. Furthermore, transients are frequently the precursors of upcoming permanent failures. In order to cope with this development, a diagnostic subsystem must especially be designed to detect and analyze such transients to reduce the failure-not-found ratio in today’s systems. Therefore, diagnostic detection mechanisms must be devised that refrain from traditional error detection techniques operating only on component-local data in favor of a system-wide view ...
