Hi,
For creating your own digital Sky130 project, you need to clone the caravel_user_project: https://github.com/efabless/caravel_user_project/ For creating your own analog/mixed Sky130 project (which gives you some analog IO Pads), you need to clone the caravan project: https://github.com/efabless/caravel_user_project_analog
I collected some documentation videos about Sky130 and various topics arount it: https://docs.google.com/spreadsheets/d/1fM301JZe_2h0-mTfyahFGRWqt3fDhnnSe2X3...
The next tapeouts are most likely around October and December.
Best regards, Philipp
