It does matter for sensitive communications systems where a few tenths of a
dB can make an actual difference. In the digital world it makes no
difference at all and is wasted effort. Nevertheless, the myth persists
because people apply the paradigm outside of proper context.

It has been shown many times with lab measurements that the shape of corners
does not matter. I agree that there are still may people claiming that they
do. Ask them for some proof!

Subject: [SI-LIST] Diff Pairs Routing - Arc / Snake Routing
Dear Experts,
Looking reference designs some vendor use Arc / Snake routing in diff pairs
(https://www.youtube.com/watch?v=ujMN-_Zc2eU#sthash.GBifJLcL.dpuf)
some don't.
Do you have some additional information about at which signal frequency it
really have real benefits in signal integrity compared to "45º angled"
layout style ?
Thanks
