I am bringing up a new Ultrascale design using DDR3. The design always passes calibration but randomly has write failures. Some of the bytes in the calibration margin window are highlighted orange. I'm wondering if this may be contributing to my random write failures. Should I be concerned by these orange highlights?

What is the memory clock frequency? Are you following all design guidelines from PG150?
