The following are the ports that are used to calibrate the IO Delays for the Versal adaptive SoC RGMII Interface.
| Signal Name | Direction | Description |
|---|---|---|
| idelay_cntvalue_in(4:0) | I | CNTVALUEIN input of all the IDELAYS that are driven by rgmii_rxd[3:0] and rgmii_rx_ctl |
| idelay_load_in | I | LOAD input of all the IDELAYS that are driven by rgmii_rxd[3:0] and rgmii_rxc |
| odelay_cntvalue_in(4:0) | I | CNTVALUEIN input of the ODELAY that drives rgmii_tx_clk |
| odelay_load_in | I | In LOAD input of the ODELAY that drives rgmii_tx_clk |
