I have created model for "inv2x" using subcircuit builder and instantiated that
Still, when I try to do kicad to ngspice, I keep getting the above error
Can you please take a look and explain the flow how to go about this error?
I can share all my subcircuit files and master file where I am trying to instantiate the subcircuit. Is there a place I can upload files?
The subcircuit creation isn't done properly. Upload the files on google drive in a folder and share the link on firstname.lastname@example.org
The designator for INV2X should be 'X' and not 'U'. Edit that using Library Editor tool of Eeschema and kicadtongspice should work afterwards.
Note : Designators for subcircuits should always be X.
