Docker images have been restored for Fault. See https://fault.readthedocs.io/en/latest/installation.html#using-the-docker-image for usage instructions.
To install the Fault binary on your computer Dockerless, use Python 3.8 or later and run python3 -m pip install -U fault-dft.
Do note you will need to install both the latest development version of IcarusVerilog (as stable IcarusVerilog doesn't work with the IHP Open PDK) and Yosys separately. Additionally, Quaigh is really recommended despite being optional. For more info, see https://fault.readthedocs.io/en/latest/installation.html#bring-your-own-dependencies
Fault 0.9.0 drops the Swift requirement to 5.6 (from 5.8) and makes Fault available as a Python module, where the Python portion is a small shim to exec the Swift executable.
Additionally, support files for the IHP Open PDK have been added to the Tech directory, and IHP Open PDK-based designs are confirmed working in CI.
