Hi @bailey! Thanks for asking, but I don't think this is necessary for wafer.space. Since the users can swap out the pad types in the pad ring, they can simply use an input-only pad when they need one. Also, as we don't have the complexity of Caravel, the final behaviour can be directly observed in the top-level GL simulation, which includes the pad cells.

Thanks @Leo Moser (mole99) . I'm a little late to the game here. Could you direct me to the documentation on how to create the pad ring?

Sure! It's this template here: https://github.com/wafer-space/gf180mcu-project-template

You install Nix, run nix-shell to enable the environment, clone the PDK make clone-pdk and run LibreLane make librelane.
