Spice netlist.PNG

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.

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

<@U04GLK4GP2S> 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)
```.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?

I just simply followed the instructions given over here:

<http://opencircuitdesign.com/open_pdks/index.html>

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

Should I clone the repository, if so then I am getting this error:
