The parameters used to generate each Aurora 8B/10B core determine the interfaces available for that specific core. The interfaces are visible in the IP symbol as seen in This Figure. In the IP symbol, if you left-click the + sign beside the interface, you can see the ports grouped in it. In this section, that is, Port Descriptions, in general, the interface appears as a single row entry followed by the ports which are grouped in it. For example in Table: User I/O Ports (TX) (TX) the USER_DATA_S_AXIS_TX is the interface and the s_axi_tx_* ports are grouped into that interface. The cores have four to six interfaces.
