Safety processes aren’t new, but standards are helping them spread throughout the supply chain: Functional safety is a topic highly driven by standards. This is due in part to legislation and regulation, but it also arises from the fact that functional safety spans a wide range of fields. Even before specific standards were introduced, there were products that met the social consensus on safety. For example, carmakers were making cars that were safe and incorporated electrical and electronic devices long before ISO 26262 was published in 2011. However, this did not necessarily require a design process for safety-critical product development that encompasses the entire supply chain all the way back to the IC manufacturer. This is because, for a long time, safety was integrated into products like cars only at a very high level - in other words: very far from the individual ICs or SiP components. The OEMs and tier 1 suppliers used only the absolutely necessary electronic components in the critical path and often ensured the safety of these with diverse redundancy approaches.
