This is a known issue for the core implemented in Artix and Kintex devices due to an Intel errata.
To work around this issue, please refer to (Xilinx Answer 51135).
An out-of-the-box solution is available to enable customers to run the Kintex-7 Connectivity TRD. This involves using a particular set of files (bit and MCS file) when running the Connectivity TRD. The files needed, k7_conn_trd.bit and kc705_conn_trd.mcs, can be found below.
For information on how to run the Connectivity TRD, please refer to UG927, Kintex-7 FPGA Connectivity Targeted Reference Design User Guide.
