I am thinking of settling in with a lot of coffee and do an full-custom D-ff or something simple in sky130. I want to define it in Schematic form (xschem?) and then do the full-custom layout (magic / klayout?) and be able to do LVS checking as well as parasitic extraction and simulation of corner performance (ngspice?). Are all the pieces there? I see that @User
merged the spice models just the other day (https://github.com/google/skywater-pdk/pull/157
), but how about LVS for example?
