can you check in the "sim.vcd" file you used to create the .svg file in the README.md? I am trying to recreate it (running on Ubuntu 18.04 & 20.04 but seem to get garbage in the .svg file). Also what were the command line parameters used to generate it? Also noticed that the generated file doesn't have an XML header (so won't display at all in Google Chrome, etc) only displays in Inkscape for me.

Here's the file.
The command I used to convert to svg was:

$ ./vcd2svg clk:b data:u out:h <sim.vcd >sim.svg

Thanks for the quick reply. I created a branch with your test file & a simpler one that I created by hand:

$timescale 1 ns $end $scope module top $end $var wire 1 ! clk $end $var reg 1 " in $end $var wire 1 # out $end $upscope $end $enddefinitions $end

This file displays fine in gtkwave (see below) but doesn't work in vcd2svg? [image: image.png]
