Hey there, Guys!
I am doing pretty hard board with QDRII+ and manufacturer requires 10ps delay within bus and between buses. So I decided to try new AD20 feature -delay based length matching.
And I have 2 odd problems: xSignals just ignore echoclock traces, I do know why so lengh matching is not working on them. And second one delay based length matching is sending me confusing signals: traces are total different length and PCB panel says so, but tuning says they are Okay,
Any Ideas?
