In the Vivado Hardware Manager, if you debug a design AXI interface with a System ILA IP, the Waveform window displays the interface slots, events, and signal groups corresponding to the interfaces being probed by the System ILA. As you can see in the figure below, the Waveform window displays both of the 2 interface slots that were probed by the System ILA IP. You can see the AXI Transactions, Write Address Channel Events, the Write Data Channel Events on slot 1. You can also see the Write Data CAXI interface slots in the Waveform window.
Figure 1. AXI Interface Transactions and Events
This waveform reports AXI interface related transactions and events on the Read, Write, Address, and Data channel events.
