The following tips will help you with your waveform analysis using the System Generator model and the Waveform Viewer:

  • Keep the Waveform Viewer open during a System Generator session. Do not close the Waveform Viewer between each simulation.
  • If you select a group of signals in the Waveform Viewer, all of the signals in the group will be cross-probed from the Waveform Viewer to the System Generator model.
  • To add multiple signals in your System Generator model to the Waveform Viewer display, you can press and hold the left mouse button and drag the mouse to draw a box around the signals, selecting them. Then right-click one of the selected signals and select Xilinx Add to Viewer in the right-click menu. The selected signals will be added to the Waveform Viewer display.
  • When naming an output signal for a block in your System Generator model, avoid using the reserved characters shown in the table below. These are reserved characters in VHDL or Verilog. If your model does contain a signal with a reserved character, its name will be changed in the Waveform Viewer display according to the following mapping table.
