Ring-oscillator PUF
Maturity plannedTargets ASIC (CMOS) onlyDifficulty HardPriority 3
PUF comparing frequencies of matched ring oscillator pairs to produce response bits, with masking of unstable pairs.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
