Undesignated Parts Requiring Annotation
Parent category: Violations Associated with Components
Default report mode: 
Summary
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.
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. A notification is also displayed in the Messages panel in the following format:
Un-Designated Part <PartDesignator>
where
- 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).
Tips
- Only one error instance will be listed in the Messages panel for each distinct designator type (U?, D?, C?, etc). Multiple errors may exist.
