Lee, I agree that it is difficult to design bad differential vias for links
below about 10 Gbps (nothing to worry), but at the higher speeds they do
require modeling and optimization to reduce the reflections and verify the
localization and isolation.

Why are we worrying about differential vias?

Subject: [SI-LIST] XTalk power flow in differential vias
Hello Everyone,
Last Friday I have uploaded visualization of crosstalk power flow in
differential vias - see #2016_13 at http://www.simberian.com/ScreenCasts.php
-> How Interconnects Work (higher quality, but may be slow), YouTube
version is available at https://youtu.be/IyuQIl8T_uE The demo video
illustrates two ways for the crosstalk reduction. I was really fascinated
with the power flow view of the crosstalk :-) As always, I will appreciate
any feedback.
Best regards,
Yuriy
