Micro-Cap 12 Full Version Is Now Free

Probably old news. This full version seems to have an incredible repertoire of functionality that makes anything else look childish. A good program for those who insist on beating the system to death with simulation:

Thank you... thank you... thank you very much...

Nice engine. Folks likely dump LT.

One guy referenced 'blender' and the way it was worded, I thought he said 'bender'. The cartoon robot (from hell).

LT Spice is great, especially so now that (most of) the ADI part models are included.

It's good of Kevin to release the source, at least that leaves open the chance of further development.

LT Spice has set the price floor. Zero.

Still, you might want to try something in both.

I've used other simulators and LT Spice is by far the best. And the cheapest!

One of my kids here runs Tina for me when we have to run a TI model.

What do you use if you want an On Semi or other model?

For a discrete, I use a similar LT Spice library part, or in extreme cases, roll my own.

I generally use the Universal Opamp and tweak the parameters to match whatever opamp I plan to use.

Some other semi makers, like EPC and Cree, actually supply working LT Spice models and circuits. Others provide instructions to adapt their models to LT.

Here's the simulation of a control loop to start up and current-regulate the power to a $200 Hittite 22 GHz distributed amplifier. The 2N3055 and such approximate the DC behavior of the amp, which has no available Spice model.
