Table 1. TX Configurable Debug Ports
Signal I/O Description
gt_txpmareset_in I

This port is used to reset the TX PMA inside the GT transceiver. It is driven High and then deasserted to start the TX PMA reset process. In sequential mode, activating this port resets both the TX PMA and the TX PCS.

gt_txpcsreset_in I This port is used to reset the TX PCS. It is driven High and then deasserted to start the PCS reset process. In sequential mode, activating this port only resets the TX PCS.
gt_txdiffctrl_in I Driver Swing Control. The default is user-specified. All listed values are in mVPPD.
Note: The peak-to-peak differential voltage is defined when TXPOSTCURSOR = 5'b00000 and TXPRECURSOR =5'b00000.

For more information on pre-cursor and post-cursor driver ports, refer to UltraScale Architecture GTH Transceivers User Guide (UG576).

gt_txpostcursor_in I Transmitter post-cursor TX pre-emphasis control. The default is user-specified. All listed values (dB) are typical.
Note: The TXPOSTCURSOR values are defined when the TXPRECURSOR =5'b00000.
gt_txprecursor_in I Transmitter pre-cursor TX pre-emphasis control. The default is user-specified. All listed values (dB) are typical.
Note: The TXPRECURSOR values are defined when the TXPOSTCURSOR =5'b00000.
