The following ports were moved under the Transceiver Debug Feature of the core (non-shared logic). If these signals were used in the previous version, the Transceiver Debug feature needs to be enabled and the appropriate signals mapped and remaining signals tied off to default values as specified in the relevant transceiver user guide.

Outputs |
gt0_drp_busy_out, gt0_drpdo_out, gt0_drprdy_out |
These signals come from the transceiver and should be connected either to an external arbiter or to the signals described in the next row. |
If there is no external arbiter, connect these signals directly to the associated signals. If they interface is not used. Can be left open. |
|
Inputs |
gt0_drpen_in, gt0_drpwe_in, gt0_drpaddr_in[8:0], gt0_drpdi_i[15:0], gt0_drpclk_in |
These signals go to the transceiver, either from an external arbiter or from the signals described in the previous row. |
If there is no external arbiter, connect these signals directly to the associated core signals. If the interface is not used, tie off the signals to ground and gt0_drpclk_in to txusrclk2 . |
