Over the holidays I helped out a friend of mine with some electronics for his Model Railroad installation. This guy is SERIOUS, he actually bought a second house in Seoul just to contain his train setup! Anyway, there was one circuit I got curious about and decided to simulate it in Spice. I noticed KiCad 5.0 was supposed to play nice (nicer) with Spice, so I gave it a try.
The quick summary is that it was a pain to get going. Some of that pain comes from infrequently using Spice, but I kept at it because the interface between KiCad and Spice looked so promising. Once I had it working, it was great. I can see this being really great once some of the issues get ironed out in future releases.
Kudos to the KiCad team responsible for this interface to Spice.
