To add probes to the waveform, select the Probes to add for the associated ILA core in the Debug Probes window, right-click, and select Add Probes to Waveform from the pop-up menu.
To add another copy of a signal or bus to the Waveform window, select the signal or bus in the Waveform window. Then select or type Ctrl+C. This copies the object to the clipboard. Select or type Ctrl+V to paste a copy of the object in the waveform.
You can do the same using the Tcl command add_wave as shown below.
add_wave -into {hw_ila_data_1.wcfg} -radix hex { {counter1} }
In this example, probe counter1 is added to the Waveform Configuration window of
hw_ila_1 and its display radix in the Waveform window is set to
hex.
