.lib ~/mabrains/skywater-pdk/libraries/sky130_fd_pr/models/sky130.lib.spice ttyrrapt

12/20/2020, 2:24 PMIf that works you can use:
.include ~/mabrains/skywater-pdk/libraries/sky130_fd_pr/models/corners/tt.spiceyrrapt
12/20/2020, 2:24 PMIt's not a problem

12/20/2020, 7:59 PM@Haseeb Ahmad I was able to simulate with no problem, I think you must include the top level model file or the 'tt' corner as @yrrapt suggested. There are lot of parameners defined all around, if you include only the capacitor file lot of definitions will be missing. Also do not specify m4_dw as instance parameter, it is not needed (it is a model parameter).
