SAFETY CRITICAL SYSTEMS

Dear Friend,

Electronic control units (ECUs) for safety critical systems have been successfully developed for decades. In recent years, ADAS and autonomous driving have resulted in an increasing number of software components and microprocessor cores in such systems. More and more customers are asking us for a methodology to consider different aspects of timing in complex safety critical systems in an efficient, practical and well-proven way.

An excellent starting point for this topic is a joint paper with Hella which was published in the proceedings of the Embedded Real-Time Software and Systems Congress. It describes “a model-based approach focusing on complex end-to-end data flows, typically encountered in safety-critical automotive control applications”. In addition, the paper illustrates “how real-time simulation models can be utilized to guide design decisions, and help to achieve safety goals defined at system level”.
