Automotive silicon design is entering a phase where functional safety, cybersecurity and artificial intelligence (AI) can no longer be treated as separate concerns. In connected, software-defined vehicles, safety outcomes depend not only on protection against random hardware faults, but also on resilience to malicious interference and software vulnerabilities. As a result, many of the decisions that determine system safety are now made at the silicon architecture level.
When ISO 26262 was first published in 2011, it marked a major step forward in structuring functional safety for automotive electronics. But the vehicles being designed today are fundamentally different. Autonomous driving, electrification, AI-based perception, vehicle-to-everything (V2X) connectivity, and centralized compute architectures were not primary considerations at the time.
