The scalars and buses shown in the Name column of the wave viewer represent the names of the probe design objects in the waveform (see the following figure). These correspond to the hardware probes of the ILA core (see the get_hw_probes Tcl command).
Immediately after triggering and uploading ILA data for the first time, the waveform viewer populates with all probes connected to the ILA core. It is possible to customize probes in the viewer in addition to removing existing probes or adding new probes to the viewer. This section covers the basic operation of the waveform viewer.
