Functional safety’s role in improved automotive safety

At the core of functional safety is fault coverage — the ability to detect and correct a potential fault and return the system to a safe state. In this blog, we'll discuss different types of fault coverage, ASIL classifications, and why ISO 26262-compliant memory is essential for functional safety.

Functional safety is the absence of unreasonable risk due to hazards caused by failures or unintended behaviors of electrical and electronic systems. The Automotive Safety Integrity level (ASIL) is measured by exposure, controllability and severity, where the corresponding ASIL level reflects the severity of harm vs. the probability of occurrence. ASIL-A is the least stringent and ASIL-D is the most stringent.
