Ports under this section are available when the Runtime switch is selected from the Configuration tab.

Table 1. Runtime Switch Signals
Name Size I/O Description
gt_drp_done_0 1 I Indicates the completion of the GT DRP operation. Used to reset the GT module.
ctl_rate_mode_0 1 I This signal causes the IP core to switch between 50G operation (0) and 40G operation (1). The clock frequencies must be corrected for the mode chosen.
txpllclksel_in_0 8 I Selects the source TX PLL clock to generate TXOUTCLK from GTWIZ IP
rxpllclksel_in_0 8 I Selects the source RX PLL clock to generate RXOUTCLK from GTWIZ IP
txsysclksel_in_0 8 I Selects the source TX sys clock for GT Channel
rxsysclksel_in_0 8 I Selects the source RX sys clock for GT Channel
rxafecfoken_0 4 I Connects to RXAFECFOKEN on transceiver channel primitives
rxdfecfokfcnum_0 16 I Connects to RXDFECFOKFCNUM on transceiver channel primitives
speed_0 1 I This signal indicates the speed with which the core is working:

1’b1 = 40G and 1’b0 = 50G

anlt_done_0 1 O Indicates the completion of Auto negotiation and Link Training

This port is available when Include AN/LT logic is selected in the Configuration tab.

rxdata_out_0 512 I RX data bus from GT IP to MAC

This port is available when Include GT subcore in example design option is selected in the GT Selection and Configuration tab.

txdata_in_0 512 O TX data bus from MAC to GT IP

This port is available when Include GT subcore in example design option is selected in the GT Selection and Configuration tab.

axi_ctl_core_mode_switch 1 O This signal can be used to switch Line rate from 40G to 50G and vice-verse when you select Include AXI4-Lite in the Configuration tab and write 1 to the 0x013C self clearing register to start the GT DRP operations.
user_reg0 32 O User-defined signal from the AXI4 register map user_reg0 register.

This port is available when Include AXI4-Lite is selected in the Configuration tab.
