11/14/2022, 9:50 PMI'm not used to schematics with the open source PDKs, as I prefer to write the netlists directly. If you want an example of the GF180 Open PDK, simulation ready, you can try cloning https://github.com/lhrodovalho/hybridCHIPS2022.
There is a folder, gf180mcuC, which contains every file needed for spice simulations there. It is only 1.8 Mb. I just copied it from the Open PDKs installation.

The circuit cannot netlisted, if the simulation run, the button is not "red".

Otherwise, you can see the rough path to the models here: https://github.com/google/skywater-pdk-libs-sky130_fd_pr/blob/f62031a1be9aefe902d6[…]6/cells/nfet_01v8/tests/sky130_fd_pr__nfet_01v8__nfet_vth.spice
