# Waveform

> Use this tool when you need to analyze and verify digital circuit simulations, as it reads and processes VCD and FST waveform files, providing insights through signal listing, value reading, and event detection. It solves problems in hardware verification and debugging workflows by evaluating complex conditional expressions across signals. Input waveform files are processed to output signal values, metadata, and event detections, making it ideal for use in digital circuit design and testing contexts.
