sv-pathfinder

VS Code extension for SystemVerilog design navigation & RTL tracing.

sv-pathfinder helps you explore elaborated SystemVerilog designs at ease, and seamlessly integrates with the waveform viewer VaporView for post-simulation debug.

Getting Started

sv-pathfinder currently supports UHDM databases for design navigation.

Generating UHDM using Surelog:

# ./slpp_all/surelog.uhdm will be generated
surelog dut.v tb.sv -elabuhdm -parse -sverilog -d uhdm

Then you can open the .uhdm in sv-pathfinder.

Compatibility Note: This extension is built with UHDM v1.84. It's recommended to use Surelog v1.84 to ensure compatibility. See Build Surelog

Limitations: only supports Linux64 for now. Tested on Ubuntu 22.04, AlmaLinux 8

Settings

  • "sv-pathfinder.remotePathPrefix": string
  • "sv-pathfinder.localPathPrefix": string
    • Replace the remote path prefix with the local path prefix when jumping to source files. This is useful when the design database is generated on the different machine/path. Only take effect when both set.

Requirements

This extension requires VS Code 1.93.0 or later
