Automotive Microcontroller End-of-Line Test via Software-Based Methodologies

The car market shows a clear trend towards an increasing presence of electronic devices in engine control systems, due to a strong market drive towards high-performance control systems. Empirical evidence shows that a conventional screening approach only targeting system functionality is not enough to reach the desired high-quality targets. In this paper a methodology is presented to generate a set of test programs that are able to perform a stress test on a widely known microcontroller core. The obtained test set is then characterized in terms of functional coverage.
