OSS CAD Suite: the one-stop shop for our tools
If you want to use our EDA tools, the easiest way is to install the binary release OSS CAD suite, which contains all required dependencies and related tools. Find the documentation here. We also have an OSS CAD Suite github action for using the tools in a github CI workflow.
Tabby CAD Suite is a commercial extension of OSS CAD Suite available from YosysHQ GmbH that additionally includes the Verific frontend for industry-grade SystemVerilog and VHDL support, formal verification with SVA, and formal apps.
