See pages 16 and 17 of the following document for an example of how to
determine differential s-partameters utilizing the .lin statement in
Hspice:

Change the '.print AC S11' statement to '.print AC Z11' to get
impedances instead of s-parameters.

Subject: [SI-LIST] Differential Z-One port
Hi all,
I have one element which I am tring to use Hspice
to find out the Leq. I am told to use the imaginary
differential Z one port to measure the Leq. The issue
is that I know how to do it single-ended but I don't
know how to do in differential. =20
I have used .LIN for the single-ended measurements but
for the differential what kind of source would I use?=20
