Bazel rules that run cocotb Python testbenches against Verilog/SystemVerilog and VHDL modules.

The two public rules are:

• cocotb_test — a Bazel test target that pairs a Verilog/VHDL *_library with one or more cocotb Python sources, runs them under the simulator picked by the active toolchain.
• cocotb_toolchain — binds cocotb to one or more cocotb_*_sim integrations (Verilator, Icarus, GHDL, NVC, Questa/ModelSim, Riviera/Active-HDL, VCS, Xcelium, DSim, xsim).

Full documentation, end-to-end example, and per-simulator status are hosted at https://hw-bzl.github.io/rules_cocotb/.
