Sheets Containing Duplicate Ports

Parent category: Violations Associated with Nets

Default report mode:


This violation occurs when two ports with the same name are detected on the same schematic sheet in the design.


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:

Sheet contains duplicate ports Port <Identifier> at <Location1> and <Location2>,


Identifier is the name of the offending port.

Location1 is the X,Y coordinates for the first instance of the particular port.

Location2 is the X,Y coordinates for the second instance of the port.

Recommendation for Resolution

With the violation selected in the Messages panel, use the Details region of the panel to quickly cross probe to the duplicate port objects. Determine which port object is in error and either rename it or delete it from the design.
