Models seem to be working fine. Single ended ring oscillator works at around 7GHz at the TT corner. Does that seem reasonable?

@Affan Abbasi: Looking through the model bins of

sky130_fd_pr/cells/nfet_01v8/sky130_fd_pr__nfet_01v8.pm3.spice

, I see bins at W=0.42 and W = 0.55, but not at W = 0.46.
