In the Interface tab (Figure 1 ), select the AXI4-Lite option to include the optional Management Interface for the TEMAC configuration (see Management Interface). If this option is not selected, the core is generated with a replacement configuration vector. If the AXI4-Lite Management Interface is not selected, the AVB option is not available. The default is to have the AXI4-Lite Management Interface selected. These features are included in the Interface tab (Figure 1 ) and Features tab (Figure 1 ) of the Vivado IDE.
When the Management Interface is enabled, select the Management Data Input/Output Interface (MDIO) option to include the optional MDIO interface. If this option is not selected, the generated core does not have the MDIO logic required to manage the objects in the Physical layer.
If MDIO is enabled, select the Add IO Buffers for MDIO Interface Ports option to insert I/O
buffers for the MDIO interface ports. This creates the bidirectional I/O bus mdio and inserts an output buffer for mdc . If this option is not selected, the core is generated with mdio_i , mdio_o, and mdio_t ports.
