Undesignated Parts Requiring Annotation

Parent category: Violations Associated with Components

Default report mode:


This violation occurs when a component in the design is found to have a default designator (with a ? suffix) - either it has yet to be annotated or the designator has been reset.


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:

Un-Designated Part <PartDesignator>,


PartDesignator is the default designator for the un-designated part (e.g. U?, D?, C?, etc).

Recommendation for Resolution

Assign a unique designator to the offending component as required. This can be done manually, by editing the designator, or through use of the Annotate dialog (Tools | Annotation |  » Annotate Schematics).

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


Only one error instance will be listed in the Messages panel for each distinct designator type (U?, D?, C?, etc). Multiple errors may exist.
