Title: How to extract the R, L, C components of two interconnect wires from spectre sim
Post by reneezl on Dec 6^th, 2017, 5:12am

Hello,

In my design, there are two interconnect wires.
a1----b1
a2----b2
I run extraction and generate the s-parameter file - wires.s4p.

I tried to run sp simulation in ADE to extract the R, L and K, coupling capacitance (Cc), and capacitance to ground (Cgnd).

I could get
R = real(1/ypm('sp 1 1))

But for Cc, Cgnd, How can I do that?

If I define a1 as port1, a2 as port2, should Cc = imag(-ypm('sp 2 1))/(2*pi*xval(ypm('sp 2 1)))? Should I leave port b1, b2 to noConn?

Thank you very much!
