Testbench.mem_rnk[0].gen_mem[0].ddr3_mem.cmd_task: at time 9912210.0 ps ERROR: Activate Failure. Initialization sequence is not complete.

Hi, I am trying to simulate a ddr3 verilog model with Xilinx MIG core which has my design connected with.  I want to read and write to ddr3 memory.

I have instantiated the ddr3 as part of my testbench and when I run the simulation, I get following as part of my tcl window and simulation stops. Can someone help?

DDR3 version is 1.74 and have followed the readme file instructions. I have also opened another ticket : https://forums.xilinx.com/t5/Memory-Interfaces/init-calib-complete-stays-low/m-p/1019308#M15242

I am sure I have messed up somewhere but any help or guidance is much appreciated.
