Sigdraw is a free, native IDE for SystemVerilog, Verilog and VHDL. It draws every module as a live block diagram that stays in sync with your code, runs the simulators you already use, and opens VCD, FST and GHW waveforms on the GPU. No account. No telemetry. Works offline.
Sigdraw is made for macOS (Apple Silicon), Linux (x86_64) and Windows (x64); the download page offers each one that’s out. This site needs JavaScript for its interactive demo. More about Sigdraw:
