What is ASIL?

ASIL, or Automotive Safety Integrity Level, is a risk classification scheme defined by the ISO 26262 standard for functional safety of road vehicles. It helps define the safety requirements for automotive components and systems by analyzing potential hazards and categorizing them based on severity, probability of exposure, and controllability. There are four ASIL levels: ASIL A (least critical), ASIL B, ASIL C, and ASIL D (most critical). The ASIL level determines the safety requirements and development processes necessary to reduce the risk of hazards to an acceptable level. It's commonly used in the development of safety-critical automotive systems like braking, steering, and airbag systems.
