rustdv-gpi-sys 0.1.0

Raw FFI declarations for the simulator programming interface. v0: hand-written VPI (IEEE 1800) subset for Icarus Verilog; the design-doc's bindgen-from-gpi.h remains the target once cocotb's GPI library can be built in-environment.

rustdv-gpi-sys

Raw FFI declarations for the simulator programming interface.

Deviation from design-doc D2.1 (documented in STATUS.md): the design calls for bindgen-generated bindings to cocotb's gpi.h. This sandbox has no cocotb GPI build and a zero-external-dependency constraint (no bindgen), so v0 binds the IEEE 1800 VPI C API directly — the same API cocotb's GPI wraps for Icarus. The declarations below are a hand-written subset of vpi_user.h, sufficient for: hierarchy lookup, value get/set, time query, and callbacks. The safe layer (rustdv-gpi) exposes a GPI-shaped API so that swapping this crate for real gpi.h bindings later is contained.

Everything here is unsafe extern "C"; no logic lives in this crate (the -sys discipline, design-doc D2.1).
