What is FuSa ?

It is part of overall safety and correct functioning of the process or system in response to its inputs. For automotive there is a standard ISO26262 is defined.

Why ISO 26262 ?

The International Standards Organization (ISO) states the following:

• ISO 26262 is intended to be applied to safety-related systems that include one or more electrical or electronic (E/E) systems and that are installed in passenger cars.
• ISO 26262 addresses possible hazards caused by malfunctioning behavior of E/E safety-related systems, including interaction of these systems.

Why FuSa is important in Semiconductor ?

The automobile industry is currently witnessing rapid change as more and more mechanical features transition to electronic systems. As a result, the functions that were in the past performed by a human driver are being supplemented by advanced driver assistance systems (ADAS), which are evolving into autonomous driving systems to enable complex technology used to safety related systems.

FuSa in Semiconductor ?

• Semiconductor component can be treated as SEooC component.
• When developing an SEooC IP, applicable safety activities are tailored as described in ISO 26262-2:2018
• If a mismatch exists between SEooC ASIL capability and ASIL requirements, an additional safety mechanism need to implement external to IP.
