Functional Safety is becoming normality as the number of complex applications (from industrial to automotive and even medical and aerospace) are heavily relying on embedded electrical and electronic (E/E) systems meeting power, performance, and area (PPA) specifications.
As vehicle safety relies not only on individual integrated circuits (ICs) but the interaction of those ICs within the electronic control unit (ECU), engineers need to analyze the traces between the ICs and develop fault models considering board-level signal and power integrity —ensuring chips will perform as intended once inside the end products, even when facing errors or unplanned or unexpected circumstances. The current Functional Safety standards demand stringent fault analysis in earlier design phases (using algorithms and models) and also robust safety monitoring at higher abstraction levels. These safety systems then need to be traced through implementation and final verification methodologies, completing the system view of functional safety.
Engineers in a wide range of markets are acknowledging the Functional Safety importance of meeting stringent security, safety, and quality standards; by developing reliable systems, their users can benefit from high-performance and secure solutions like driver safety, comfort, in-car infotainment, and fuel efficiency. For businesses, achieving safety requirements mean the difference between capitalizing on new opportunities and missing the mark, due to the advancements in technology driving product design and development.
Because the high demand for sophisticated embedded electronics, addressing Functional Safety is now propagating through the whole supply chain: from semiconductor technologies to design tools, together with methodologies and processes in all stages.
