I’m brand new to KiCad and electronic cad software. I’ve downloaded last night’s v5 nightly build and am trying to capture a schematic (draw a simple LED circuit) and simulate it. I’ve gotten to the point where the Spice Simulator opens, runs and then gives a number of errors like “Unable to find definition of model led - default assumed”.
It sounds like I need a “model” file for the LED for Ngspice. Is that correct? Where would I find that?
Later, I would like to draw more complicated circuits, simulate them, and then create PCBs. I would like to use a chip like a TI LM2678 step down buck converter, which does not appear in the schematic library at all. What files/info do I need to collect to use the chip in KiCad?
I believe I need a KiCad “symbol”, a “footprint”, and a Ngspice/PSpice compatible “model”. Is that correct? Is there a standard place to find these if they are not installed by default? Is there documentation for these file formats and where the files need to be placed or imported to be used by KiCad/Ngspice?
