In the Virtex-6 QUAD115 and QUAD105 (for devices with 2 columns of GTs), perform the resistor calibration for the circuit that is used by all remaining GT tiles.If these QUADs are not instantiated and used with the IBERT core, this calibration will not occur and GT operation might not work reliably.
This should not be a problem in 13.3 and later versions because a DRC check will be added to the wizard to ensure that the user always follows this requirement.
