Perhaps someone could comment on simulation software, particularly on the simple/beginner side of things?

For instance, recently I got some supercapacitors and had a few ideas for a simple circuit (consisting of resistors, diodes and capacitors). I did an EE unit when I was at school a long time ago but wanted to get a better understanding of how my circuit would behave, particularly voltage levels and discharge rates over time.

I was expecting there would be some software which would allow me to draw a simple circuit, specify input voltages and press 'play', allowing me to see how the circuit acted as a live simulation and see charts of voltage at particular nodes over time.

However, despite googling around, I couldnt find such software geared towards visualisation of simple analog circuits...

Happy to look at OSS or propriety software, I was expecting to find something used in academia but no such luck.

Any recommendations?





Wow, thanks - I played with it for hours and promptly signed up for the paid version. Great tool.


MITx's 6.002x hax an online circuit sim. There's also QUCS for the desktop.


Circuitlab is keeping me busy at the moment but thanks I'll check this out.
