You can customize the look and feel of the Waveform window, and then save the Waveform configuration to reuse in future simulation runs. The Waveform configuration file defines the displayed signals and the display characteristics of those signals.
  1. In the Waveform window, click the Settings button on the title bar menu.

    The Waveform Options dialog box opens to the General tab.

  2. Ensure the Default Radix is set to Hexadecimal.

    This defines the default number format for all signals in the Waveform window. The radix can also be set for individual objects in the Waveform window to override the default.

  3. Select the Draw Waveform Shadow, as shown in the following figure, to enable or disable the shading under the signal waveform.

    By default, a waveform is shaded under the high transitions to make it easier to recognize the transitions and states in the Waveform window.

    You can also enable or disable signal indices so that each signal or group of signals is identified with an index number in the Waveform window.

  4. Check or uncheck the Show signal indices check box to enable or disable the signal list numbering.

  5. Check or uncheck the Show grid lines check box to enable or disable the grid lines in the waveform window.
  6. Check the Snap to Transition check box to snap the cursor to transition edges.
  7. In the Waveform Options dialog box, select the Colors view.

    Examine the Waveform Color Options dialog box. You can configure the coloring for elements of the Waveform window to customize the look and feel. You can specify custom colors to display waveforms of certain values, so you can quickly identify signals in an unknown state or an uninitialized state.

    The Waveform window configures your preferences. You can save the current waveform configuration so it is available for use in future AMD Vivado™ simulation sessions.

    By default, the Vivado simulator saves the current waveform configuration setting as testbench_behav.wcfg.

  8. In the Waveform window sidebar menu, select the Save Wave Configuration button .
  9. Save the Wave Configuration into the project folder with the filename tutorial_1.wcfg.
  10. Click Yes. The file is added to the project simulation fileset, sim_1, for archive purposes.
Tip: You can also load a previously saved waveform configuration file using the File > Simulation Waveform > Open Configuration command.
