The official Yosys docs recommend OSS CAD Suite as the easiest way to use Yosys. In practice it is also the fastest cross-platform path into a wider open-source RTL toolchain because it bundles several related tools.
Use OSS CAD Suite when you want a packaged environment instead of installing each open-source EDA tool one by one.
The official docs list nightly builds for `linux-x64`, `linux-arm64`, `darwin-x64`, `darwin-arm64`, and `windows-x64`.
For fish shell, the official docs also provide `environment.fish` and `fish_add_path` examples.
The official docs say you can also run `./activate` once inside the extracted directory.
The official docs recommend extracting to a path without spaces on Windows.
Instead of stitching together many package managers, you download one archive, activate one environment, and then begin with the lab or the Yosys and Verilator guides immediately.
This guide points back to the official OSS CAD Suite project for the real archive downloads and activation scripts. It summarizes the setup and keeps the attribution with upstream.
