When I look at the HDL in my MIG design, I see that the COL_WIDTH parameter is set to 11 when it should be set to a value of 10.
parameter COL_WIDTH = 11, // # of memory column bits.
To work around the problem, set the top-level parameter "COL_WIDTH" to a value of 10. This should be set in sim_tb_top.v/vhd for simulation and <design_name>.v/vhd for implementation and hardware.
If this is a multi-controller design, then the parameter will be called C#_DDR2_COL_WIDTH.
