Note	SystemVerilog proof of concept of the security block in S-3160, with Verilator testbenches. Per its README, it gates an example Int8 adder, supports ECDSA (secp256k1) or HSS/LMS signatures, and omits production features including constant-time field arithmetic, a configurable public key and redundant blocks. The repository also has a pynq-z2 folder with an FPGA build script and a Python client; the README reports no FPGA results.
