I have generated a netlist of an inverter simulation as shown using xschem, but when I input this netlist into ngspice it fails to recognize the model of the transistor.

Copy code

.lib /usr/local/share/pdk/sky130A/libs.tech/ngspice/sky130.lib.spice

@Mudasir your

.lib

statement is incomplete. Specify the complete path of the

sky130.lib.spice

file followed by the

tt

process corner (or ss, ff, fs, sf)

Copy code

.lib /usr/local/share/pdk/sky130A/libs.tech/ngspice/sky130.lib.spice tt

Oh yes completely overlooked that, but now I have corrected and getting this error:

And I see this is because I have no spice folder inside the folder ..../libs.ref/sky130_fd_pr/spice, but why is that shouldn't it be included in the pdk.

Should be in the pdk. Are you using volare?

Maybe this is easier https://github.com/efabless/volare
