Hi all,
I am interested in a tool that takes a simple spice like netlist and generates the symbolic nodal equations and then uses the symbolic math toold box to solve the equations for all nodes.
The closest I could find was the SCAM tool (<http://www.mathworks.com/matlabcentral/fileexchange/3443-scam-a-tool-for-symbolically-solving-circuit-equations>)
While it works well for simple circuit elements it currently does not support dependent voltage sources (VCVS, VCCS, CCVS, CCCS).
Can anyone point me to a tool/utility that supports dependent sources as well?
My goal is to take a circuit netlist (much like SCAM's) and then generate nodal equations using KCL and them solve these system of equations symbolically in MATLAB to get transfer functions.
Thanks, Bhupi

Another website, https://circuitnav.pythonanywhere.com/, provides an online symbolic circuit analysis tool which uses netlists generated by LTspice, Micro-Cap and Tina-TI.
