Version Found: MIG 7 Series v1.8
Version Resolved: See (Xilinx Answer 45195)
When generating a MIG 7 Series DDR3/DDR2 core with the Debug Signals enabled, a dbg_dqs VIO port is available to change the byte group for the resultant Chipscope signals. The mux_rd_rise/fall buses are not connected to dbg_dqs and therefore the results seen are always related to DQS byte group 0.
Currently, dbg_dqs is connected to the cmp_data and rd_data buses as well as the tap counts. It will be added to the mux_rd_rise/fall signals in a future release.
In the meantime, the rd_data bus can be used to analyze the data.
