Open-source hardware security SoC on SKY130 – RO-PUF + FSM + ARX Hash, targeting

[maomaoati]

Hi all,

I just open-sourced a hardware security SoC I designed
independently, targeting Fabless tapeout on SKY130.

Three-layer security architecture:
- 64-stage RO-PUF: chip-unique 64-bit fingerprint
  (Hamming weight = 32/64, verified)
- 6-state anomaly detection FSM: zero-cycle alert latency,
  permanent hardware lock
- ARX hash engine: 128-bit identity token + Phys-XOR audit chain

Verified with Icarus Verilog 12.0 on EDA Playground:
61 test cases, 100% pass rate on all three core modules.
Targeting ChipFoundry shuttle CI2609 (SKY130).

The entire design was done on a mobile phone —
no computer, no commercial tools.

Happy to discuss the design or verification approach.
