The whole design, in view
The native desktop app that draws the SystemVerilog, Verilog and VHDL you already have — as a diagram you can edit, a waveform you can scrub, and live values sitting on the wires. Every view, one file.
Sigdraw is a native desktop IDE for macOS and Linux. It reads the VCD your simulator already writes — Verilator, Icarus, xsim, GHDL, NVC — and puts the values on the wires, so you debug by looking at the circuit.
