Best Practices for ISO 26262 ASIL Ready Automotive ADAS SoCs
By: Ron DiGiuseppe, Senior Strategic Marketing Manager, Synopsys
According to National Highway Traffic Safety Administration (NHTSA), 94 percent of all automotive accidents are caused by the driver primarily due to poor recognition, poor decision making or poor performance1. Automotive OEMs are adding new advanced driver assistance systems (ADAS) to improve safety for functions such as pedestrian detection/avoidance, lane departure warning/correction, traffic sign recognition, surround view, drowsiness monitoring and other applications (Figure 1). Fueled by consumer interest and government regulations to improve road safety, auto makers are requiring Tier 1 and semiconductor suppliers to develop ADAS system-on-chips (SoCs) that incorporate the latest multimedia standards, run multiple vision base algorithms, and combine image and radar system sensor data. To implement the advanced protocols required to meet high performance operation, the ADAS SoCs use leading edge design and process technologies that are more stringent than most high-end consumer applications. Designers of this new class of ADAS SoCs rely on IP suppliers to help overcome the challenges of implementing the application-specific IP requirements as well as to meet the ISO 26262 functional safety requirements of safety critical automotive applications in shortening design and maturation cycles.
