Creating and Modifying a Signal Group

Use the Debug Settings Signal Groups command to create a group of signals or to add or remove signals from a previously defined group of signals. Use this option in conjunction with the Debug Settings Display Signals command when you are in the process of debugging a design.

Creating a Signal Group

Follow this procedure to create a signal group.

1. Select Debug Settings Signal Groups.
   
   The Signal Groups command invokes the Signal Groups dialog box, shown in the “Signal Groups Dialog Box” figure, which enables you to select the signal groups that you want to probe.

3. Type the name of the group you want to create in the Name field of the Group Name popup dialog box.

   Click Apply to apply the filter to the signals displayed in the Available Signals list box. To redisplay the complete signal list, click Clear.
   
   
5. Select the signals you want to include in the group by highlighting the desired signals in the Available Signals list box and selecting the > button to move the highlighted signals to the Grouped Signals list box.
   
   To remove signals from the Grouped Signals list box, select the signals and click the < button.
   
   To add or remove all the signals displayed in a list box, use the << or >> button.
   
   To rearrange the order of the signals displayed in the Grouped Signals list box, use the Up and Down buttons below the list box.
   
   
6. Click Save to save the new group.
   
   
7. Click Close to exit the Signal Groups window.
   
   
8. Refer to the “Creating and Modifying a Signal List” section for information on how to include the groups you created in your display list.
