I have a question concerning routing of diff pairs.
I’m using micro vias from layer 1 to 4, core via from 4 to 9 and micro from 9 to 12.
BGA pins on layer 1 and caps on the bottom.
When routing a single net I can easily drop down to the layer we need using the arrows to do so.
When routing defined diff pairs, I cannot. I end up going to single net mode until both are on the layer I want then back to multi-plow.
Is there an alternative to my time consuming method?
