The AMD Waveform Viewer displays a waveform diagram of selected signals in your Vitis Model Composer design. Waveforms can be displayed in the Waveform Viewer after running a Simulink simulation. Inputs and outputs of blocks in the HDL Blockset can be displayed in the Waveform Viewer.
In your design, you can select the signals that will be monitored in the Waveform Viewer. As you develop and troubleshoot your design, the waveforms for the signals you are monitoring will be updated in the Waveform Viewer each time you simulate the model.
The AMD Waveform Viewer used with Vitis Model Composer is also used by other tools in the AMD Vivado™ toolset. The Waveform Viewer is used to analyze a design and debug code in the Vivado simulator and to display data captured by the Integrated Logic Analyzer (ILA) for in-system debugging.
For information on using the Waveform Viewer to develop and troubleshoot your design, see this link in the Vivado Design Suite User Guide: Logic Simulation (UG900).
