How to plot the graph of the effective capacitance in Hspice

[peter_hawk]

Dear all :
I have a question about Hspice.
How to plot the graph of the effective capacitance between 2 nodes.
Between these two nodes, there are some elements.
For example, "G" and "B" in the following circuit

Thanks a lot!

you can measure the effective capacitance between 2 nodes, by the capacitance define.

 

[bkat]

C = I / wV
V = 1V
f = 1/2PI
--> C = I

you can measure the current with Hspice
then C = I

Re: How to plot the graph of the effective capacitance in Hs

You can use .net function in Hspice and polt the z11(r) to find out the cap.
