DPI protected Verilog instead of encryption

Encrypted Verilog is weak (see referenced ACM CCS paper) so the project compiles secret RTL with Verilator into a DPI-accessible shared object, shipping the wrapper and object instead of plaintext. The approach trades encryption for obfuscation via compiler, avoids leaking RTL, and is implemented: libraries build, pass Verilator CI, and run with XM. Significant limits remain — fixed top‑level parameters, simulator build matrix and packaging burdens — but the proof‑of‑concept works.
