1. Virtual File System
All .v files are linked automatically — no `include needed. Instantiate
modules by name.
2. Timing Diagrams
Add a VCD dump to your testbench's initial block:
initial begin
$dumpfile("waveform.vcd");
$dumpvars(0, tb_top);
end
3. DSP / Hex Data
Create a .hex file — the Signal Gen button appears to generate a noisy 8-bit
sine wave. Inject with $readmemh("file.hex", mem);
4. Export
Use ↓ SVG or ↓ PNG in the Timing / RTL tabs. Both export the full
diagram with correct bounds and a dark background. Fit ⊞ auto-scales to the window first.
5. Keyboard Shortcuts
Ctrl+Enter — Simulate
Ctrl+H — Find & Replace
Tab — 4-space indent
Escape — Close panels
