MIG v3.6-v3.61 Virtex-6 DDR3 - Debug signals to decrement Phase Detector IODELAY taps is wired incorrectly


The debug signal "dbg_pd_dec_dqs" should decrement Phase Detector IODELAY taps in memc_ui_top.v/.vhd

However it is incorrectly wired to increment.


The following shows the incorrect connection of "dbg_pd_dec_dqs":
     .dbg_pd_inc_dqs            (dbg_inc_rd_dqs),
     .dbg_pd_dec_dqs            (dbg_inc_rd_dqs),

The correct connection is:
     .dbg_pd_inc_dqs            (dbg_inc_rd_dqs),
     .dbg_pd_dec_dqs            (dbg_dec_rd_dqs),

This issue is fixed in the ISE 13.1 MIG v3.7 software release.
