vcd

GTKWave is a fully featured GTK+ based wave viewer for Unix and Win32 which reads LXT, LXT2, VZT, FST, and GHW files as well as standard Verilog VCD/EVCD files and allows their viewing.

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.

A simple digital waveform viewer with vi-like key bindings.

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.

A parser for Value Change Dump (VCD) files as specified in the IEEE System Verilog 1800-2012 standard.

A repository that implements Tywaves: enabling a type-based waveform debugging for Chisel and Tydi-Chisel. Mapping from Chisel level code to values dumped by simulators is now possible thanks to Tywaves!

Build Tools for VMware Aria provides development and release management tools for implementing automation solutions based on the VMware Aria Suite and VMware Cloud Director. The solution enables Virtual Infrastructure Administrators and Automation Developers to use standard DevOps practices for managing and deploying content.
