Parent category: Violations Associated with Components

Default report mode:


This violation occurs when a sheet symbol contains two sheet entries possessing the same name.


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:

Sheet Symbol with duplicate entries Sheet Entry <Identifier> at <Location1> and <Location2>


  • Identifier is used to represent the offending sheet entry. The identifier appears in the format SheetSymbolName-SheetEntryName(SheetEntryIOType).
  • Location1 is the X,Y coordinates for the first violating sheet entry.
  • Location2 is the X,Y coordinates for the second violating sheet entry.

Recommendation for Resolution

Change the name of the offending sheet entry object as required, either by editing the name in-situ or by double-clicking on the offending sheet entry and editing its Name in the Properties section of the Properties panel - which presents all properties for the selected sheet entry.

A sheet entry name can also be edited from the Sheet Entries section on the General tab of the Properties panel - when browsing the properties for the selected parent sheet symbol.


  • 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).
