Automated failure and tolerance analysis as a combined consideration for the proof of safety of electronic systems

Abstract:
Several industries, especially the automotive industry, are moving towards higher and higher portions of electronics in their products. And they become increasingly complex and hard to analyze. This presents a challenging burden when it comes to the required proof of functional safety manufacturers have to provide for their products. Not only random faults, but also component tolerances can lead to unexpected safety hazards. Today’s methods struggle to keep up with these challenges. This paper identifies some key challenges with today’s methods and presents a new one, that uses computer automation and a model-based approach to improve this process. It is outlined how the new method does the same things better while also adding new capabilities.
