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), i.e. 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. 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:
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.
- 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).
