hello! I apologize for what is certainly user error on my part, but I'm a bit stuck integrating xschem+ngspice+skywater130A. xschem alone seems to work. I can see all of the symbols in the "top.sch" in the pdk. ngspice appears to work in the command line with pdk models. However, when I try to start a sim from xschem, I get errors like the following, in "test_mim_cap.sch"

/home/username/.xschem/simulations/test_mim_cap.spice: No such file or directory

and in "test_inv.sch"

Error: unknown subckt: x4 z[1] z[0] vcc not w_n=1 l_n=0.15 w_p=2 l_p=0.15 m=1

it's as though I have failed to convince the tool to look for the right things in the right places, and I'm not sure how to properly fix the xschemrc, which I suspect is the problem. I followed the instructions in Stefan's youtube video to get this far. any help debugging would be great.
