I use this a lot for quickly testing things out when I am not entirely sure what I need. It's incredibly powerful, and give you scopes so you can verify things work. It may be very old and look ancient by modern standards but it's much more usable for me. Also I don't need sonmething to simulate an Arduino, I need something to say test a op-amp summing amplifier.
