:: Hey all, can any of you please recommend good mixed-signal :: simulation :: software (such as SPICE)? I want to be able to do things like lay :: out :: a schematic, apply power, virtually stick in oscilloscope probes :: and :: see what I get on a graph. I don't care if it's free/pay/whatever. You can check out AutotraxEDA - www.kov.com it is a CAD and Spice software in one package - it is being upgraded to using dot Net technology currently and any buglets will disappear. You could download SwitcherCad from Linear Technology (free) - it comes with a whole load of gumph for their switcher chips, but is actually a spice program - or if you like CLI stuff and I've just lost the link, but there is a free version which requires hand entry rather than drawing a nice circuit. Check out BrownBag software, they used to have a lite version of Spice, which could be upgraded if your purchased Proteus i think it was.
