This is an overview of using ngspice in KiCAD to create a simple simulation.

The barrier to entry for this stuff is high. This is partly because the documentation almost always assumes a ton of experience and partly because the subject material itself is highly specialized. Another factor is that the community itself is somewhat daunting and often full of people that tend to make things even more complicated. Thank you for making great videos. Thank you for helping to make this knowledge accessible.

Thanks for doing this video. I've had a hell of a time finding current documentation on using KiCad to do simulations. I'm going to try creating a Pierce-gate oscillator to generate a clock signal, and I want to make sure it actually works in theory before I buy the parts. Wish my luck!

Good luck @oberon4278. Totally unrelated: Oberon is the name of a dog in one of my favorite audible book series. Any relation?

I'm trying to add a 1n4007 diode but I'm constantly getting "unable to find definition of model 1n4007". I checked demos I found they were using 1n4048, so I used it but the same error keeps popping up. What should I do?

if the component is not in the spice lib it wont work, I believe.

You have to add the model. OnSemi has all the diode models if you'd like to use theirs. You will use the D for ngspice and add the 1N4007 model.

@@ericbredder9015 Thanks for your video, but what I'm trying to find out is how and where to add a model--what file it goes in, what directory that file goes in, etc. There seems to be a very loose use of the word "library" as I dig around looking for information. Some sources talk about a models library, and others seem to indicate that "library" refers to the Kicad symbols library and that the model data goes in them. If I go to Symbol Properties for a component and click on Edit Spice Model and go to the Model tab, it's not clear to me what the Library field is. When I click on the Select File button, it doesn't take me to my symbol directories (and of course it knows where they are) but just the general file system. Is it expecting the name of the particular Kicad symbol (.lib) file? Well, there's lots of entries in the .lib file that would apply, so will it automatically match (for instance) "2N3904"--the name of the model I want to enter--with the component in that library by the same name? That's very unclear, and it ought to already know what component I'm editing and what library it's in. Do you have any insight on this? And do people sometimes keep their spice models in separate spice libraries and then link to them? For some reason, clarity is eluding me on this, and I'm not a Kicad noob, I'm just new to using it for simulation. Thanks.
