Parent category: Violations Associated with Harnesses

Default report mode:


This violation occurs when there are conflicting Harness Entries for the same Harness Type, either at a graphical or textual level (in the Harness Definition File).


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:

Conflicting Harness Definition for <HarnessType>


  • HarnessType is the current conflicting Harness Type.

Recommendation for Resolution

Use the Details region of the Messages panel to quickly cross probe to the offending objects (Harness Definition Files and Harness Connectors) within the Signal Harness. Update the Harness Definition File to reflect the changes, or remove the offending Harness Entry.

Harness Definition Files for the design can be found in the Settings - Harness Definitions Files folder for that project, in the Projects panel. For more information, see Working with Signal Harnesses.
