Critical Issue
Description
ALTMEMPHY calibration uses PLL reconfiguration to update PLL phases. Thus, dynamic PLL reconfiguration is required.
Since each ALTMEMPHY interface must be calibrated separately and may require different adjustments to the PLL clocks, the PLLs cannot be merged.
For further information, refer to the ALTMEMPHY sections in the 12.1 version of the External Memory Interface Handbook.
