Parent category: Violations Associated with Harnesses

Default report mode:


This violation occurs when a Signal Harness connecting Sheet Entries or connecting a Sheet Entry to a Port is missing a Harness Type.

For more information on signal harnesses, see Working with Signal Harnesses.


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:

Missing Harness Type on Signal Harness

Recommendation for Resolution

Use the Details region of the Messages panel to quickly cross-probe to the offending objects (Sheet Entries or Ports) within the Signal Harness. Specify a Harness Type across the Signal Harness for at least one of the objects:

  • Port - specify a Harness Type in the Properties section on the General tab of the Properties panel (which presents all properties for the selected object).
  • Sheet Entry - specify a Harness Type in the Properties section of the Properties panel (which presents all properties for the selected object).


  • 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).
