Parent category: Violations Associated with Nets

Default report mode: 


This violation occurs when a Net Name of a pin of a schematic FPGA component does not match the external source file Net Name of a pin.


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:

External  <NetLabelName> and Schematic <NetLabelNameare Unsynchronized for Pin <xx>


  • NetLabelName is the name of the offending net label.
  • xx is the pin number.

Recommendation for Resolution

In the Pin Mapper dialog with the offending Pin selected, in the Schematic region, access the drop-down solution options then choose Update Pin File () to transfer the net name from the schematic to the external FPGA pin file then recompile the project.


  • 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).
