This section lists the interface signals for the AXI Interconnect core and each of the underlying AXI infrastructure cores.
In Table: AXI Interconnect Core Slave I/O Signals through Table: AXI Infrastructure Core Global Port Signals, the Default column shows whether the input signal is required (REQ) or, if not, its default value if left unconnected. For the AXI Interconnect core and the AXI Crossbar core, signal connections are required only for the SI and MI that are used. Signals that are not used in a particular protocol configuration are indicated by “d/c” (do not care).
