1) It seems it is more suitable for high school and upper students who want to learn electronics better and go to further topics. It is also simple for them to easily model without missing inside too many buttons and properties. 2) It seems it is not too hard to integrate new futures to make it

As a sage user and an engineer I would rather use gEDA for this stuff. Granted it doesn't have capacitance/inductance meters built into it but you don't really use those outside of school. The current crop of opensource SPICE and Microcap style engines for circuit simulation do a very good job

This seems interesting. I teach circuits and networks every semester as an application of ODEs/systems of ODEs. The EMF is not necessarily constant and occasionally we might have a variable term (eg, a variable capacitor). Questions: 1. Does his program allow non-constant terms and symbolic

Hello, http://www.circuitengine.com is my site. It uses Gaussian elimination and a fifth order adaptive step-size Runga-Kutta solver to simulate electric circuits that are drawn by the user. I created a login for the sage development team to use. Please feel free to experiment with my program.

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
