sv-pathfinder
VS Code extension for SystemVerilog design navigation, RTL tracing, schematic viewer, and waveform integration with the Vaporview waveform viewer.
VS Code Marketplace | Open VSX | GitHub
Getting Started walks through prerequisites,
setup, and opening your first design.
Features
Navigate a design
- Browse the elaborated design hierarchy
- Jump to source: module definitions/instantiations, signal
declarations, generate blocks, and more
- Go back/forward
- Find instance
- Select an instance from the Modules view
- Waveform value & add to waveform (waveform integration)
Setup & details → Open a design.
Schematic viewer
- Render the RTL (or gate-level) structure of any scope
- Right-click a scope → Show Schematic
- Step into child scope / Step out to parent scope
- Jump to source editor for cell/wire
- Find in schematic viewer
- Waveform value & add to waveform (waveform integration)
Setup & details → SCHEMATIC.md.
With the Vaporview extension:
- Inline signal values — show signal values in
the source editor and schematic view, for the given waveform marker time
- Add signals to the waveform — from hierarchy view, source editor, or schematic → Show in Waveform / Add All
Variables in Scope to Waveform
Documentation
- Getting Started — prerequisites, backends (
.f / .uhdm), opening a
design, and all settings.
- SCHEMATIC.md — schematic setup (OSS CAD Suite), backend tiers, elaboration
modes, curated/partial filelists, and all
schematic* settings.
