GTKWAVE
Open-source waveform viewer for Verilog and VHDL dumps
GPL-2.0
ABOUT
Simulation dumps are huge and vendor viewers lock teams into a license. GTKWave reads VCD, FST, LXT, and GHW so engineers inspect analog and digital signals, search nets, and annotate RTL from an open viewer.
INTEGRATION GUIDE
1. Open a Verilog VCD or FST dump and inspect digital waveforms
2. View GHDL GHW dumps from VHDL simulations
3. Save a signal set from a large SoC dump for later debug
4. Annotate Verilog RTL with values at a chosen timestep
