Spice

it seems everyone has moved to linux for modeling circuits. I guess all of the windows modelers have serious limitations unless you want to spend a TON of money.. so I was looking for a live CD distro of linux that had Spice (graphical version) for one of my co-workers and ran across LTSPICE from Linear technologies. it seems this is a full blown windows modeler! so for all you students (and silicon based designers) out there check out LTSPICE.
