Wow, my field! :) I would like to add that SAGE can open a new door to circuit analysis, thanks to its symbolic manipulation.
A friend of mine adopted the techniques to solve the circuits defined by a netlist like in SPICE. If you adopt that same technique in SAGE, you are allowed to define one or more terms symbolically, so you can study transfer functions and stuff like that by simply drawing the circuit in any SPICE program. Regarding Circuit Engine, I have to say that it looks pretty simple and slightly lacking interesting features, but I don't want to be rude toward such an appreciable initiative. I hope that it relies on well spread standards like SPICE or SPECTRE netlist Thanks for focusing on this as well :) Maurizio On Jul 26, 10:24 pm, David Joyner <wdjoy...@gmail.com> wrote: > This seems interesting. > > I teach circuits and networks every semester as an application of > ODEs/systems of ODEs.
