MIG 7 Series DDR3L - MIG GUI allows higher value (400MHz) than the DS182 specification (333Mhz/667 Mbps) for Kintex-7 FBG in -1 for DDR3L (1.35V IO)

Description

Version Found: MIG 7 Series v2.0 rev1

Version Resolved: See (Xilinx Answer 54025)

The MIG 7 Series GUI incorrectly allows DDR3L interfaces to target up to 400MHz in the Kintex-7 FBG package -1 speedgrade devices.

This does not match the DS182 (v2.13) specification of 333MHz (667Mbps).

Solution

The GUI will correctly limit this memory/FPGA part combination to 333MHz in the next release.

Until then, please ensure that frequencies above 333MHz are not selected within the tool.
