Synopsys says its PUF (Physical Unclonable Function) IP, a chip fingerprint design, is the first to clear both ISO 26262 (auto functional safety) and ISO/SAE 21434 (auto cybersecurity), though the multi tier supply chain is the harder test.
Cars now run perception, planning, and braking on the same silicon, and that silicon is what regulators and attackers are learning to target.
Synopsys says its Automotive PUF Premium IP is the industry's first PUF to clear both ISO 26262 functional-safety certification and ISO/SAE 21434 automotive cybersecurity at the same time (Semiconductor Engineering). A PUF, or Physical Unclonable Function, is a device fingerprint drawn from random silicon variation inside a chip's own SRAM. The IP derives root keys on demand and never stores them, leaving nothing in flash to copy (Synopsys product page). It runs on standard SRAM across foundries and process nodes, and pairs a 256-bit key with a NIST SP 800-90 random bit generator (Synopsys datasheet).
What the certifications cover: ASIL B for random faults and ASIL D for systematic ones on the safety side; side-channel, fault-injection, and reverse-engineering countermeasures plus a Threat Analysis and Risk Assessment with no backdoors on the cyber side.
What they do not yet prove is that any car on the road carries the IP. Synopsys cites more than 1.5 billion deployed devices and 15-plus years in aerospace, defense, and government, but the announcement named no automotive customer, OEM integration, or independent test-house validation. The harder question is whether a vendor certificate survives the multi-tier supplier chain, where a Tier-2 ECU maker buys silicon it did not certify.
