Abstract
RISC-V is emerging as a viable platform for automotive-grade embedded computing, with recent ISO 26262 ASIL-D certifications of commercial RISC-V processor IP demonstrating readiness for safety-critical deployment in autonomous driving systems. However, functional safety in automotive systems is fundamentally a certification problem rather than a processor problem: the dominant costs arise from diagnostic coverage analysis, toolchain qualification, fault injection campaigns, safety- case generation, and compliance with ISO 26262, ISO 21448 (SOTIF), and ISO/SAE 21434.
This paper provides a structured analytical framework and expert-driven research roadmap for enabling economically superior certification of automotive-grade RISC-V platforms. Rather than proposing a single algorithmic breakthrough, we contribute: (1) a certification economics framework with formal cost and advantage models for strategic decision support; (2) an ML assisted certification framework mapping LLMs, knowledge graphs, reinforcement learning, and graph neural networks to specific certification bottlenecks; (3) a five-level RISC-V Safety Maturity Model (RSMM) for evaluating platform certifiability; and (4) an illustrative case study applying the framework to an ASIL-D autonomous emergency braking (AEB) ECU.
We present a structured comparison of Arm and RISC-V architectures across eight functional safety dimensions, address the convergence of ISO 26262, ISO 21448, and ISO/SAE 21434 for autonomous driving, and define quantitative evaluation metrics for certification cost reduction. The paper is positioned as an analytical perspective contribution that structures the research space and identifies the highest-value problems for the RISC-V automotive certification ecosystem.
