Unknown Harness Type

Parent category: Violations Associated with Harnesses

Default report mode:


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.


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:

Unknown Harness Type <HarnessType>,


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.
