fsdb

Open-source, license-free MCP server for RTL waveform debug: reads FST waveforms (VCD/FSDB auto-convert) plus a SystemVerilog netlist, with 34 tools covering driver analysis, value/X tracing, pass-fail waveform diff, a browser wave viewer the agent drives, and pre-simulation static analysis.

Open-source, evidence-driven MCP server for RTL simulation debugging: correlate VCS/Xcelium logs, VCD/FSDB waveforms, SystemVerilog/UVM source, hierarchy, and connectivity to trace failures to root cause.

🌊 CLI tool for RTL waveform (VCD/FST/FSDB) inspection

High-level digital waveform analysis in Python.

FSDB is a collection of Go libraries providing a key-value store on your file system

Convert fsdb/vcd file to json(wavedrom format) and svg

This package provides an extension for the impulse framework, focusing on the import and (optionally) export of Electronic Design Automation (EDA) waveform data including VCD, FSDB and FST.

🗃️ Simple NodeJS File System Database.

impulse EDA Playground - Comprehensive showcase of waveform analysis and protocol verification with realistic samples in VCD, FST, FSDB formats plus TLM transactions and pin-level protocol analysis for AXI4, ACE, and CHI

A file system json-based database library which mimics Mongoose, offering easy data storage and CRUD operations using JSON files.

Open-source, user-built bridge that gives svw bounded, read-only access to FSDB waveforms through a locally licensed reader SDK.

grep for waveforms — read signal values, clock frequency, and transitions from Synopsys FSDB, Cadence SST2, and open VCD dumps, straight from the shell. Deterministic output, runs locally, no viewer. CLI + MCP server + Claude Code skill.
