Duplicate Part Designators

Modified by Susan Riege on Feb 28, 2019

Parent category: Violations Associated with Components

Default report mode:

Summary

This violation occurs when at least two parts across source schematic sheets in a design have the same designator associated to them.

Notification

If compiler errors and warnings are enabled for display on the schematic (enabled on the Schematic - Compiler page of the Preferences dialog), an offending object will display a colored squiggle beneath it. Hovering over the object will display a pop-up hint that summarizes the violation. A notification is also displayed in the Messages panel in the following format:

Duplicate Component Designators <PartDesignator> at <Location1> and <Location2>

where:

  • PartDesignator is the offending designator.
  • Location1 is the X,Y coordinates marking the center of the parent part for the first instance of the offending designator.
  • Location2 is the X,Y coordinates marking the center of the parent part for the second instance of the offending designator.

Recommendation for Resolution

Assign different and unique designators to the duplicates as required. This can be done manually by editing each offending designator or through use of the Annotate dialog (Tools » Annotation » Annotate Schematics).

Alternatively, reset the duplicate component designators first using the Tools » Annotation » Reset Duplicate Schematic Designators command then use the Tools » Annotation » Annotate Schematics Quietly command to annotate without launching the Annotate dialog.

Tip

  • Object hints will only appear provided the Enable Connectivity Insight option is enabled on the System - Design Insight page of the Preferences dialog. Use the controls associated with the Object Hints entry in the Connectivity Insight Options region of the page to determine the launch style for such hints (Mouse Hover and/or Alt+Double Click).
