Multisim from electronics workbench is OK, try **broken link removed**. It has simulations limitations, I'm afraid, as in number of components you can add, but you are still allowed quite a lot, so it's OK up to medium sized projects. There is also no save on the demo.
There are a couple different versions of spice that are available for free. The berkely spice works well. I use one called ng-spice (or something like that) that works well.
hi
i can give you two programs we're using in school, one for simulating logical circuits and one for simulating easy ''basic'' circuits.
just mail : sankt-seibel@firemail.de
hi,
i'm really sorry, i've spend the last hour trying to send you the programs, but it didn't work. firemail made a problem, and i also couldn't add the *.zip as an attachement in here (think it's too big).
just look out for 'locad for windows' and 'crocodile clips' @ kazaa .

As a general principle, when you post a URL, you should test it by previewing and clicking on the link to be certain that what you have posted actually works.
You could try Orcad's Capture Lite. NO LIMITATIONS in terms of simulation or whatever. I dunno from where you could get it, but I have it because of my textbook: it was inside it...
