Optimizing a Fault Campaign for Complex Mixed-Signal Devices


Image for Optimizing a Fault Campaign for Complex Mixed-Signal Devices event


The primary objective of a fault campaign is to understand whether the safety architecture sufficiently prevents random failures from violating ISO 26262 safety requirements for both commercial and passenger automobiles. To complete fault injection, faults are injected and propagated in the design to validate the functional correctness of the safety mechanisms and to classify each fault. Fault classifications are then used to generate the required safety metrics. 

The complexity of automotive ICs continues to grow exponentially, challenging even the most veteran teams to deliver innovative products to market while simultaneously ensuring safety through the operational life of the product. Project teams prove safety through fault injection, but traditional approaches are no longer feasible. Safety activities, flows, and solutions should not be an afterthought and must be considered at project conception. Teams must decide on the correct mix of fault injection tools based on the application and safety architecture. Those who do it correctly are the ones who will expedite fault campaign closure and succeed in delivering tomorrow’s automotive electronic systems designs today.

This presentation details how to effectively set up and execute an ISO 26262 fault campaign for mixed signal designs.
