This discussion focuses on software options for generating differential equations from circuit diagrams. LTspice is highlighted as a free and effective circuit simulation tool for solving equations and comparing results. While commercial packages may exist for generating simultaneous differential equations from netlists, they are often part of expensive circuit analysis suites. The conversation also touches on the possibility of developing custom software using MATLAB for this purpose.
PREREQUISITESElectrical engineers, circuit designers, and students interested in circuit analysis and simulation techniques.
gneill said:Solve your equation, plot the results, and then compare to the output of a circuit simulation. LTspice is a good, free, simulator. It's worthwhile getting familiar with such a useful tool.
I presume that there must be commercial packages out there that will produce a set of simultaneous differential equations from a netlist, but I couldn't say if they'd be generated in a form that would be usable to you. Also it would likely be just one component of a larger, rather expensive circuit analysis package.
The only affordable software I'm aware of that will generate the differential equations from a circuit diagram is located between the ears
