You can display the inputs and outputs of blocks in the HDL Blockset in the Waveform Viewer. The data necessary to draw each signal’s waveform is not stored with the design; it is generated by simulation. You can only display a signal’s waveform after adding the signal to the Waveform Viewer and simulating the model.
Follow these steps to add signals to the Waveform Viewer display:
- With the Waveform Viewer open, select a signal in the Vitis Model Composer model.
You can also select multiple signals by using Shift + click to select additional signals.
Note: The Waveform Viewer can only display the output signal for the Gateway In block. - Right-click one of the selected signals in the Model Composer model
and select AMD Add to Viewer
in the right-click menu.Note: If you select a signal that appears in the Waveform Viewer, AMD Add to Viewer does not appear in the right-click menu.
The signal names of the selected signals appear in the Waveform Viewer.
Only the names of the added signals appear in the Waveform Viewer, because the Waveform Viewer does not have the data to draw the signal’s waveform until you simulate the design.
- Simulate the model.
When the simulation finishes, the waveforms for the added signals display in the Waveform Viewer.
