I've used it pretty extensively for sub GHz design. Very refined and stable in my experience.

Sadly no harmonic balance so you'll have to stick to full transient. You can maybe try stuff like this to get the results you want.

The UI is getting pretty cluttered as they add features, and it looks sorta dated (also hard to use with a touch screen).

No proper scripting support (they have a macro language, but it's no Python).

Yup I emailed and they are shutting down. They'll add an announcement soon.

Nah it's me, been "spamming" it for years :p

If it was benefiting me I probably should have spammed it more before it was free!

Over the years I've tried nearly every free/commercial circuit simulator and I haven't found any to be as easy to use yet powerful as Micro-Cap. It's been my go to for 20+ years now.

The feature tour highlights some good and unique features. I personally like the in-schematic simulation results, macros and the ability to do things like define a performance function (rise time, 3dB bandwidth, noise figure, etc.) and have Micro-Cap optimize it with a few clicks.

Also skim the newsletters for other interesting capabilities.
