Controlling the Waveform Display Parameters

This section describes the features available for customizing your waveform window. After generating a waveform, you can modify its format by changing the display mode from graphics to text, modifying the radix of your groups, and changing the color of the waveform window background and signals. In addition, you can change the size of the waveform and the position of the windows on the screen.

Description of the Text Window

In the text mode, the waveform window displays a textual representation of the device states you specified for viewing, as shown in the “Active Waveform Window (Textual View)” figure. This view is a tabular display of the readback information.

Figure 7.3 Active Waveform Window (Textual View)

The textual waveform window contains the following areas.

Signals

This column shows the names of the displayed signals and signal groups.

Cycle

The data in this column reflects the position of the vertical cursor in the text data window. The header shows the number of the selected snapshot. The column shows the readback values of the selected signals and signal groups.

Text Data Window

This column contains the following areas.

• Cycle Scale
  
  This area, above the text data area, shows the snapshot counts, number of applied clock cycles, and reset states.
  
  Each snapshot count appears as a red triangle. The number of clock cycles applied between consecutive snapshots appears above each snapshot mark.
  
  Each Reset state appears as a blue diamond with a vertical line.
  
  
• Text Data
  
  This display area shows text data for the readback values of signals and signal groups.
  
  

Description of the Graphical Window

In the graphical mode, the waveform window displays a graphical representation of the signals you specified for viewing, as shown in the “Active Waveform Window (Graphical View)” figure.

Figure 7.4 Active Waveform Window (Graphical View)

The Graphical Waveform window includes the following areas.

Signals

This column shows the names of the displayed signals and signal groups.

Cycle

The data in this column reflects the position of the vertical cursor in the waveform data window. The header shows the number of the selected snapshot. The column shows the readback value of the selected signals and signal groups.

Waveform Data Window

This column contains the following areas.

• Cycle Scale
  
  This area, above the waveform data area, shows the snapshot counts, number of applied clock cycles, and reset states.
  
  Each snapshot count appears as a red triangle. The number of clock cycles applied between consecutive snapshots appears above each snapshot mark.
  
  Each Reset state appears as a blue diamond with a vertical line.
  
  
• Waveform Data
  
  This display area shows waveforms for the readback values of signals and signal groups.
  
  Each signal appears as a semi-rectangular wave.
  
  Each signal group appears as a complete hexagonal wave.
  
  

Changing the Size of the Waveform

Use the options listed under the View menu to change the size of the waveform on your screen or to update your screen.

• Select View Zoom In or click the Zoom In toolbar button to increase the size of your waveform.
  
  
  
  
• Select View Zoom Out or click the Zoom Out toolbar button to decrease the size of your waveform.
  
  
  
  
• Select View Zoom To Fit or click the Zoom To Fit toolbar button to fit all of the waveform cycles into the current window.
  
  
  
  
• Select View Zoom Reset or click the Zoom Reset toolbar button to return the display to the default state.
  
  
  
  
• Select View Refresh to redraw the elements on your screen and update the current waveform using the latest debugging modifications.
  
  

Controlling the Position of the Windows

To change the way the windows are displayed on your screen, follow these guidelines. The window that is in focus processes the commands you invoke.

• Select Window Arrange to arrange the iconized windows as non-overlapping tiles at the bottom of the main window.
  
  
• Select Window Cascade to display each window on top of the preceding window in a cascading arrangement.
  
  
• Select Window Tile Horizontally to arrange the windows horizontally.
  
  
• Select Window Tile Vertically to arrange the windows vertically.
  
  

Changing the Radix of Displayed Signal Groups

Use the View Group Radix command to display or change the radices of your signal groups. Possible radices include binary, octal, decimal, and hexadecimal. The radix is applied to all groups.

1. Select View Group Radix from the menu.
   
   
2. Click on the desired radix.
   
   

Changing the Color of the Waveform Window

You can change the color of the signals and background of the waveform window.

1. To modify a signal color, click on the signal in the waveform window that you want to modify.
   
   
2. Select View Color Signals.
   
   
3. From the Color dialog box, select a color or create a custom color to select.
   
   
4. Click OK to apply the color change.
   
   
5. To modify the background color, click on the waveform window that you want to modify.
   
   
6. Select View Background Color.
   
   
7. From the Color dialog box, select a color or create a custom color to select.
   
   
8. Click OK to apply the color change.
   
   

Removing a Signal

Use the popup menu commands in the Waveform window to remove signal waveforms.

1. Select the signal on the waveform.
   
   
2. Select Delete Signals from the popup menu.
