vcdparser

A simple VCD parser to access the contents of a VCD file in python.

The goal is to provide an easy to use, lightweight parser for VCD files. The parser also aims to be quite fast (for a python library 😉).

What does it do?

This library contains a simple parser, which reads in VCD files and provides you with the raw data from this file.

How to use

To install the latest version from PyPI use pip install vcdparser. After that you can import the parser using import vcdparser.parser.

This is a simple script showing you how to parse a file and get the first 10 changes of a signal named "CLK":

import vcdparser.parser

vcd = parser.parse_vcd_file("your_file_path.vcd")
clk_id = vcd.get_id("CLK")

count = 0
for t in vcd.timesteps:
    if clk_id in t.variables:
        count += 1
        print(f"CLK changed to {t.variables[clk_id]}")
        if count >= 10:
            break
