When I generate a Virtex-6 QDRII+ FPGA design using MIG v3.3, awarning message similar to the following is displayed in the terminal console window on the Bank Selection page:
"QString::arg: Argument missing: Step 1 of 4:
Select the Address/Control group in the enabled banks (or) select the "Restore Defaults" for recommended bank selections., 5"
This warning occurs only if the Address/Control group is selected in an outer column bank.
This is a false warning and can be safely ignored.
This warning was removed in MIG v3.4 (released with ISE Design Suite 12.1).
