The following are the ports that are used to calibrate the IO Delays used by the RGMII interface in Versal devices.
| Signal Name | Direction | Description |
|---|---|---|
| idelay_cnt_val[4:0] | In | CNTVALUEIN input of all the IDELAYS that are driven by rgmii_rxd[3:0] and rgmii_rx_ctl |
| idelay_load | In | LOAD input of all the IDELAYS that are driven by rgmii_rxd[3:0] and rgmii_rx_ctl |
| odelay_cnt_val[4:0] | In | CNTVALUEIN input of the ODELAY that drives rgmii_tx_clk |
| odelay_load | In | LOAD input of the ODELAY that drives rgmii_tx_clk |
