OSS CAD Suite is a multi-platform binary distribution of open-source digital logic design and verification tools, including Yosys, GHDL, ABC, Amaranth, and Migen. This repository contains the build scripts and nightly release infrastructure for producing those binaries across Linux, macOS, and Windows.

Use cases

• install yosys and open source FPGA tools without building from source
• get a prebuilt Verilog synthesis and simulation toolchain for Linux, macOS, or Windows
• set up an open source digital design environment for Verilog, VHDL, Amaranth, or Migen
• download nightly binaries for RTL synthesis, formal verification, and FPGA place and route
• set up a CI pipeline for Verilog or VHDL verification using prebuilt tools
• program and test FPGAs using only open source software

When to choose

• you need ready-to-use binaries of Yosys, GHDL, or related HDL tools without compiling them yourself
• you want a consistent, all-in-one open source digital design toolchain across multiple platforms
• you want recent nightly builds with the latest tool versions
• you are setting up FPGA or HDL workflows in CI or on machines without build toolchains

When to avoid

• you need commercial-grade SystemVerilog, VHDL, or SVA support, which requires the proprietary Tabby CAD Suite
• you need to customize tool build flags or patch the tools themselves
• you only need a single tool and prefer installing it via your system package manager
• you require long-term-stable pinned releases rather than nightly snapshots
