I am using a 7 series GTX.
Previously I had a Virtex-7 design.
When I try to migrate to Kintex-7, I see the below error.
In Virtex-7 architecture, connection without a clock buffer is allowed if the IBUFDS_GTE2 and MMCM are located in the same clock region.
However, in Kintex-7, IBUFDS_GTE2 cannot drive MMCM clock inputs directly.
You will need to insert a BUFG or a BUFH in between.
