Parent category: Violations Associated with Harnesses

Default report mode:

Summary

This violation occurs when a Harness Type is found but a matching definition cannot be found in a Harness Definition file. This can happen for one of two reasons:

  1. A Signal Harness is connected to an object (Sheet Entry, Port, or Harness Entry) with an unknown Harness Type.
  2. When a Harness Entry in a Harness Definition file refers to an unknown Harness Type.
For more information on signal harnesses, see Working with Signal Harnesses.

Notification

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:

Unknown Harness Type <HarnessType>

where:

  • HarnessType is the current unknown Harness Type.

Recommendation for Resolution

Use the Details region of the Messages panel to quickly cross-probe to the offending object and then ensure that Sheet Entries, Ports and Harness Entries have a known Harness Type and that Harness Definitions are accurate:

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

Tip

  • 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).
