Important

Since May 2022, packages providing Architecture Definition assets do not include CLI utilities/wrappers to interact with Yosys, Verilog-to-Routing, etc. For backwards compatibility, end-users can install Python package f4pga from gh:chipsalliance/f4pga. For instance: pip install https://github.com/chipsalliance/f4pga/archive/main.zip#subdirectory=f4pga.
