In this paper, we base on the fault tree analysis (FTA) to propose an Automotive Safety Integrity Level (ASIL)-oriented hardware design framework for safety-critical automotive systems, where ASIL plays a key component in the ISO 26262 safety standard to measure risk of a specific system component. There are two contributions in this framework: FTA-based weak-point analysis and ASIL-oriented fault-tolerant design methodologies. The former can rapidly identify the weak-points for safety through the fault tree analysis, and the latter can effectively introduce the safety mechanisms in the hardware design to fulfill the requirements of target ASIL. We use the autonomous emergency braking (AEB) system to demonstrate the effectiveness of the proposed design framework.
