Done:

No routing of parallel I/O across MGT power islands in adjacent layer

local GTX links DC coupled are ok. Requires special settings in firmware !

GTH always AC coupled!

MGTHBIAS precision resistor track to FPGA must be less than 5 pF and the resistance must be less than 10Ω . (is ~1pf/24 mR)

Open:

Tune MGTAVCC to 1.03V typ. (+/- 0.03)
