Error in Graphical Display of DQ Calibration Margin in EMIF Toolkit for DDR2 and DDR3 SDRAM Controller with UniPHY

Description

The right-hand side of the Read Data Valid Windows and Write Data Valid Windows display in the External Memory Interface Toolkit displays one too many green boxes in each row.

Resolution

Margin values reported in the Margining Status Report are correct. Rely on the values in the Margining Status Report rather than the graphical representations of the Read Data Valid Windows and Write Data Valid Windows.
