Hello,

https://github.com/Nic30/pyDigitalWaveTools/blob/master/tests/vcdParser_test.py#L42

Try if it works for you, I can eventually prepare some examples if required, currently I do not remember if the json format is exactly same but the differences should be minimal if there are any.

Thank you for responding. Is there any possibility if you can add option to accept VCD files and convert them to Json and then show waveform instead of directly accepting json file format?

I can not utilize directly pyDigitalWaveTools because it is a Python. But there are several vcd parsers in JS, eg. https://github.com/wavedrom/vcd https://github.com/ahmed-agiza/vcd-parser and many others.

Do you think you can look at the existing libraries and try them a little bit and find out which one is the best?
Or at least collect some practical info?
I can make an integration, but I do not have time to look at all the libraries.

Sure I will check some libraries and then let you know

waveFile.txt
I have tried this library. https://github.com/ahmed-agiza/vcd-parser
I passed VCD file and it converted it into json format. but when i passed that json file to your d3-wave project it is not generating wave file, because of format difference in JSON file.
Can you just try it and check the Json format output it is generating and how can i change it according to Json format used in your project.
I have also attached the VCD file code im trying to run on d3-wave.

Implementation currently resides in https://github.com/Nic30/vscode-extension-digitalcircuitanalysis/blob/main/src/media/vcdParser.ts I will move it to this or independent soon.
