Abstract: Due to the rapid development of integrated circuit design and manufacturing technologies, chip-level functional safety-related devices have made great progress. The development & validation methodology of functional safety- related IC has become the focus of the industry. This paper discusses the functional safety techniques introduced in IEC61508 standard, summarizes the main technical characteristics of functional safety-related IC at present, and presents a V-model for functional safety-related IC development based on the analysis of IEC61508 standard. Finally, it puts forward a complete methodology of functional safety-related IC development conforming to IEC61508 to design an ASIC, and gives a short conclusion on the design result.
