Sorry about that.
Am asking about programs for circuit design and what ever else there is but basically what a beginner needs to concern himself with for now.
Switcher CAD III is a great sim program. If you're looking for a digital sim program, it's not good though. If you do oscillation, rf, etc. it's great. And best of all its totally free w/ no restrictions. I think the website is linear.com . . . if not, just google for Switcher CAD III.
Also, it will run under Wine for Linux no problem.
If you want to do circuitboards as well, I'm kinda partial to the CircuitMaker/TraxMaker package, even though it's not necessarily a great program. It works good enough, and they have it at my school.
