[SI-LIST] Re: questions for 2-layer PCB simulation

Hi Tina:

I can't speak for other simulation tools, but in HyperLynx, you would
import the 2-layer board, and then add a 1000 mil thick layer of air
(Er=3D1.0), followed by a reference plane.  Both the field solver guys =
and
customers who have tried this say that it works well.  If you want to
validate this approach on one of your designs, let me know, and I'll try
to connect you with the right people.=20
