Duplicate Part Designators

Parent category: Violations Associated with Components

Default report mode:


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


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. A notification is also displayed in the Messages panel in the following format:

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


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 |  command, then use the Tools | Annotation |  » Annotate Schematics Quietly command to annotate without launching the Annotate dialog.
