Parent category: Violations Associated with Nets

Default report mode: 


This violation occurs when a Port, Sheet Entry, or Net Label within a Signal Harness has a name in the form [X..Y] indicating a bus object.


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:

Bus <Object> <ObjectName> at <Location> placed on a harness


  • Object is the offending port, sheet entry, or net label.
  • ObjectName is the name of the offending object.
  • Location is the X,Y coordinates for the offending object.

Recommendation for Resolution

Use the Details region of the Messages panel to quickly cross probe to the offending object and modify the name so that it does not use bus syntax.


  • 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).
