Yeah, usually the trick is in configuring the parts. Not sure about these software, but other simulators provide manufacturer-defined models as well as template parts which you can customize to obtain something closer to your application. Have you ever used Spice?

I spent two weeks in Trieste a couple years ago and got to visit a few of the northern cities, might return there some time.
In fact I'll be moving to Spain this year, plan to spend a few months there.
