17.5.2. Transceiver Reconfiguration Interface
Signal Name | Direction | Description |
---|---|---|
reconfig_to_xcvr [(<n>×70)-1:0] | Output | Parallel reconfiguration bus from the Transceiver Reconfiguration Controller to the PHY IP Core. |
reconfig_from_xcvr [(<n>×46)-1:0] | Input | Parallel reconfiguration bus from the PHY IP core to the Transceiver Reconfiguration Controller. |
reconfig_busy | Output | When asserted, indicates that a reconfiguration operation is in progress and no further reconfiguration operations should be performed. You can monitor this signal to determine the status of the Transceiver Reconfiguration Controller. Alternatively, you can monitor the busy bit of the control and status registers of any reconfiguration feature to determine the status of the Transceiver Reconfiguration Controller. |
tx_cal_busy | Output | This optional signal is asserted while initial TX calibration is in progress and no further reconfiguration operations should be performed. It is also asserted if reconfiguration controller is reset. It will not be asserted if you manually re-trigger the calibration IP. You can monitor this signal to determine the status of the Transceiver Reconfiguration Controller. Arria V devices require DCD calibration for channels with data rates equal to or greater than 4.9152 Gbps. In Arria V devices, you cannot run DCD calibration for multiple channels on the same side of a device simultaneously. If your design includes more than 1 Transceiver Reconfiguration Controller on a single side of the FPGA, you must daisy chain the tx_cal_busy output port to the next cal_busy_in input port on the same side of the FPGA. |
rx_cal_busy | Output | This optional signal is asserted while initial RX calibration is in progress and no further reconfiguration operations should be performed. It is also asserted if reconfiguration controller is reset. It will not be asserted if you manually re-trigger the calibration IP. You can monitor this signal to determine the status of the Transceiver Reconfiguration Controller. |
