I have an engineer who wants a detailed model of a via.
Mostly he is looking for capacitance. The part of the
system he is working on runs at less than 5 MHz. The
via is blind, with the closed end of the via ending
fairly close to a ground plane.

My questions:
1. Can one analyze this in HSPICE?
2. Does anyone have a spice deck with anywhere near
a starting point, that they can share.
The vendor support engineer could not come up with
anything helpful.
Thanks,
