Symbolic Linear Circuit Analysis of a passive filter
SLiCAP can be used to evaluate the behavior of linear dynamic circuits. The (not very meaningful) circuit below shows that SLiCAP can handle loops of inductors and capacitors and voltage sources. SLiCAP evaluates the DC transfer by calculating (lim s--> 0) of a transfer function and easily finds poles and zeros at zero frequency.
