When I implement the default design generated by theCORE Generator software for the ML605 board, an error similar to the following occurs: "ERROR:ConstraintSystem:59 - Constraint <INST "core/pcie_2_0_i/pcie_gt_i/gtx_v6_i/GTXD.GTX" LOC = GTXE1_X0Y15;> [../../example_design/xilinx_pcie_2_0_ep_v6_08_lane_gen1_xc6vlx240t-ff1156-1_ML605.ucf(111)]: INST "core/pcie_2_0_i/pcie_gt_i/gtx_v6_i/GTXD.GTX" not found. Please verify that: 1. The specified design element actually exists in the original design. 2. The specified object is spelled correctly in the constraint source file."

Make sure the correct device is selected while creating the CORE Generator project and that ML605 is selected in the GUI while configuring the parameters for core generation.
