I hate the UI in LTspice because the complete toolbar is missing on the Mac version. Adding models to ngspice in Kicad is pretty simple: Open the properties of the regular symbol, add simulation model and browse to e.g. the downloaded pspice model from TI. No messing with creating a symbol like in LTspice. You have to remember to use the Spice symbols for your ground, and I always forget that.<div class=""><br class=""></div><div class="">I have never compared the results between these two, could be interesting.

For one thing it’s windows-only, so no, I can’t use it. Still use
the somewhat outdated Mac version of LTspice. I now tend to use
KiCAD’s built in ngspice every now and then, as it’s already in
KiCAD. (<a href="https://www.kicad.org/discover/spice/" moz-do-not-send="true" class="moz-txt-link-freetext">https://www.kicad.org/discover/spice/</a>)

<div class=""><p class="">Hey list,</p><p class="">the guy who originally made LTspice, IIRC, some time

Supposedly, you can code simulated elaborate
