UltraScale+ Memory IP - The SFVB784 package has incorrect data rates in PL Memory Interfaces

Description

Version Found: DDR4 v2.2 (Rev. 1), DDR3 v1.4 (Rev. 1), RLDRAM3 v1.4 (Rev. 1), QDRII+ v1.4 (Rev. 1), QDRIV v2.0 (Rev. 1), LPDDR3 v1.0 (Rev. 1)

Version Resolved: See (Xilinx Answer 58435)

(DS922) v1.5 August 29th, 2017 Table 27, shows valid data rates for various packages in PL Memory Interfaces.

The SFVB784 package is limited to one speed grade lower than All FFV packages when run above 1600 Mb/s.

In Vivado 2017.2 and earlier releases, if the user selects a SVFB784 package and customizes a PL Memory Interface, the data rates are incorrect in the Customization GUI for the selected memory device.

The data rates are the same as All FFV packages.

Solution

In Vivado 2017.3, the issue has been corrected in the Customization GUI to reflect (DS922) v1.5 August 29th, 2017 Table 27.

The SFVB784 package is now limited to one speed grade lower than All FFV packages when run above 1600 Mb/s.
