Hi there,  We’ve got a customized board with AGIB022R31B2E1V implementing 4 an identical EMIF interfaces.  When examined with the EMIF toolkit for re-calibration and margining, we acquired conflicting outcomes.   First, each recalibration and site visitors take a look at throughout the toolkit handed. 

Nonetheless, the DQS enter, and DQ enter are all misplaced.  The learn window of 468ps is method over the theoretical 312ps for a 3200Gbps DDR4.

Vref_In calibration end result can be unconvincing.

DQS, DQ output and Vref_out calibrations seems to be appropriate.  Similar conduct occurred to all 4 EMIF/DDR4.

Reminiscence configurations are:

Does anybody have any thought why the calibration report appears flawed whereas each re-calibration and site visitors take a look at indicated in any other case.
