Hiya,

Is there any simple but effective circuit simulation software out there? preferably with a scope as i specifically want to try variations with R2R ladders and see what steppy waveforms i get.

Also preferably free!

and i want the moon on a stick too

Have a look at this one:

https://sourceforge.net/projects/qucs/

It's free. Quote from the project site:

-----
"The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Transient, Noise and Harmonic Balance analysis. Pure digital simulations are also supported.
Features

- schematic capture
- analog and digital simulations
- data visualization

There is also Digital Works*. Its library is rather limited although you should be able to recreate chips with it.
I use it from time to time to test some ideas (like the fibonacci generator Wink

).

*I don't think that is the official site so download at your own risk.

I tried balancing on a stick but it broke.
