Hey all! Somewhere between five and 15 years ago (I've been out of the game a while), I had a lumped circuit simulator. And it was extremely useful, for a few reasons;
A) It was interactive. The time step was very low (I think it was adjustable), but you could actually click to trigger buttons and switches and actually see the results in real-time. As a bonus, it also highlighted which connections were "live" at a given time (mostly useful for digital simulation).
B) It never failed. This is important to me because the current simulator I'm messing with (QUCS) usually fails, and I'm sick of building designs based on what the computer can or can't calculate. In the program I used, the circuit might fail if you messed something up or had no idea what you were doing, but the simulation would always run.
C) It had virtually every feasible component. Every Zener diode, every transistor, every op-amp, and more IC chips than I'd ever be able to count. Its only limit for the latter category would be for complex chips (it seemed to top out at buffers, shift registers, and 7-segment drivers; things composed of only a few logic blocks).
Now, I'm wondering, does anyone know what program this could have been? Or, probably just as useful, are there any other current analog/digital simulators with those same features?
