Hello support,
when a part from EasyEda library is used you cannot see whether this part has already a spice definition.
You have to go through Super menu->netlist->spice.
Please show an attribute "spice" in part attributes and connect it with a button to a text editor.
So:
- you can see at once whether this part has a spice model
- on clicking a button near the spice attribute a text editor should popup and show the spice definition
kindly regards
Wolfgang
