Hello, I have two questions regarding to the i.MX8 platform:
1) Pin delays for the iMX8 package
We have the reference Allegro board file LAY-29336_A.brd and there are some info inside the constraint manager.
Could somebody explain these numbers in Relative Delay - Delta: Tolerance? Attached is a picture with details.
There are two questions for this picture:
A) Why there are not used pin delays in this board file? Could somebody convert the blue numbers to pin delays?
B) Why the red numbers are not with the same length?
2) Could somebody tell us minimal length for the LPDDR4 lines?
Thank you & best regards,
Team Leader PCB Layout
