Take care to figure out what the model order is, and that it’s mapped properly to your component. SPICE model pin numbering often doesn’t match component/package numbering.

1M does not mean 1 megaohm, it means 1 miliohm.

Make sure your component values mean in SPICE what they mean to you.

In practice, stringing it all together is not the EASIEST user experience.Īs far as Altium is concerned, here are my high-level notes: Theoretically (2) and (3) should just be convenient front end interfaces in your native CAD domain to an external spice simulation engine.

Associate SPICE models with each component in itĪll three packages are great at (1).

The gist of simulation with any of these CAD packages is

That said, this video took FOREVER to put together, so we’ll see how quick I am to follow it up for Eagle and Kicad. This is part 1 of a 3 part series, covering “how to simulate with SPICE” in each of Altium Designer, Autodesk Eagle, and Kicad, mostly so I know exactly how to do it quickly.
