history

Project history and usage

netlistsvg is a specialized electronic-design visualization tool: it draws SVG schematics from Yosys JSON netlists, using ELK/elkjs for layout. The README documents both a CLI and a browser bundle, and shows the normal flow as Verilog through Yosys `write_json` into an SVG diagram.

Project history

The npm registry records `netlistsvg` 0.0.1 on 2019-03-29 and 1.0.2 on 2020-12-12. The GitHub repository listed 1.0.2 as the latest release and shows the project as a TypeScript/JavaScript tool by Neil Turley.

The README says Yosys can generate the input JSON with `write_json`, and suggests `prep -top my_top_module` or `prep -top my_top_module -flatten` depending on whether the user wants module boxes or lower-level logic. It also documents digital and analog skins and custom SVG component libraries.

Adoption history

Adoption is niche but real inside open-source hardware and HDL workflows. The npm downloads API reported 8,188 downloads from 2026-05-30 through 2026-06-28; the Homebrew API generated on 2026-07-01 reported 306 installs over 365 days. The GitHub repository showed about 801 stars and 106 forks when checked.

Its package footprint also reflects the niche: Homebrew packages it with Node and tests against Yosys, while npm is the natural distribution path for users who want the CLI or web bundle.

How it is used

The canonical CLI use is `netlistsvg input_json_file -o output_svg_file --skin skin_file`, after generating the input with Yosys. Users use it for readable diagrams from HDL, debugging synthesis output, documentation images, or teaching examples.

Package nerds reach for it when Graphviz-style layout is too generic for circuits. The skin system lets a user map cell aliases to SVG component templates, making generated diagrams look like digital logic blocks or analog schematic symbols instead of arbitrary boxes.

Why package nerds care

netlistsvg matters because it sits at a useful package boundary: Yosys produces machine-readable netlists, and netlistsvg turns them into diagrams that humans can inspect. That is exactly the kind of small bridge tool that makes an EDA toolchain nicer without becoming the toolchain.
