With the PDK being open, does anyone know if any kind of NDAs are still required to get a chip fabbed? While free-of-charge fabbing is quite nice, I think being NDA-free is even more important so all work including the tweaks necessary for fabbing can be published, e.g. on GitHub.

BTW, it will be nice to try this together with the OpenROAD tools [1]. They have support for Google's PDK on their to-do list (planned for q3, but I doubt it will be ready that fast).
