@User I did. The example for the model I'm trying to use lives under the cells directory and uses this to pull in models:

.include "../../../models/r+c/res_typical__cap_typical__lin.spice"
.include "../../../models/r+c/res_typical__cap_typical.spice"
.include "../../../models/corners/tt.spice"

What I need to know is how I'm supposed to use this library as a user. I have no clue why the includes in the example are the way they are, I'm not trying to develop the library. If I'm supposed to do that then what is the top level

sky130.lib.spice

even for?
