Waveform

About

Waveform is an MCP (Model Context Protocol) server designed to facilitate the reading and in-depth analysis of digital waveform files, specifically supporting VCD (Value Change Dump) and FST (Fast Signal Trace) formats. Leveraging the 'wellen' library, it offers a robust set of functionalities including opening waveform files, listing signals with hierarchical paths, reading signal values at specific time indices, retrieving signal metadata, and finding signal changes or events based on complex conditional expressions. It supports both STDIO and a streamable HTTP server for flexible access, enabling remote waveform analysis and integration into various development workflows.

Key Features

• Read signal values at specific time indices or across multiple points.
• Open and manage VCD/FST waveform files.
• List and filter signals by hierarchical paths and names.
• Find signal events and conditional transitions using complex expressions.
• 4 GitHub stars
• Streamable HTTP server for remote access and shared waveform analysis.

Use Cases

• Remote inspection of waveform data for collaborative hardware development.
• Automated analysis and debugging of digital circuit simulations.
• Scripting complex behavioral checks and event detection within VCD/FST files.
