Simple free analog circuit simulator idealCircuit. Works with ideal components using the same algorithm as NL5, however is much simpler and does not need a license.
I tried this simulator and a major error came up trying to exit. It froze my computer and would not shut down. Why? I am not experienced enough to figure it out.
It's really hard to tell without knowing the details. If you are still interested in fixing this and willing to help with troubleshooting, please write to [email protected].
Thank you.
