1.3.2.5 Dynamic Reconfiguration Interface

DRI performs the runtime configuration of transceiver PMA/PCS, PCIe, CCC, and Transmit PLLs after initialization. DRI ports are routed through hardwired connections.

In this demo design, DRI is used to perform the runtime calibration of transceiver and CCC. Q2_LANE0 is enabled to expose target to the Transceiver interface and PLL0_NW is enabled to expose target to the CCC interface, as shown in the following figure.
