Configurations
Figure 4–2 illustrates one configuration of the XAUI IP core. As this figure illustrates,
if your variant includes a single instantiation of the XAUI IP core, the transceiver
reconfiguration control logic is included in the XAUI PHY IP core. For Stratix V
devices the Transceiver Reconfiguration Controller must always be external. Refer to
Chapter 10, Transceiver Reconfiguration Controller for more information about this IP
core.
