LogiCORE IP Tri-Mode Ethernet MAC v5.1 RGMII support on Kintex-7 device

Description

Is RGMII supported on Kintex-7 devices?

Solution

To use RGMII on 7 series devices, install the Rev2 update of the core provided in (Xilinx Answer 40624). The patch in the Rev2 update has ODELAYs removed since they do not exist in HR I/Os. To provide required clock data relationship, an additional 90 degree phase shifted clock from the DCM has been used, which is passed down into the RGMII interface.
