symbolic circuit simulator
Hi there:
Sometimes, I need to find the multiport Z(Y,S,T) matrix
from a circuit netlist (Spice netlist).
Then the questions are:
1) Can circuit simulator(Hspice) give a multiport Z(Y,S,T) matrix
output?
Suggestions as how to combine several 2port matrix into
multiport matrix technique are also welcome.
2) I not only want to find the numerical solution but also
want to find a symoblic solution. Is there any circuit simulator
being able to do that?
For example, I have a 2port network as below
L L

C

L L
I can manually calculate the Z(Y,S,T) matrix with a
symbolic expression. But how about a network with
hundreds passive elements? Any suggestion/idea?
If there is no such kind of tool, I may consider to
write a freeware to do that. )
Thanks
