Mismatched Bus Label Ordering

Modified by Susan Riege on Feb 28, 2019
All Contents

Parent category: Violations Associated with Buses

Default report mode: 

Summary

This violation occurs when two net identifiers associated with the same bus slice define bus labels with ordering that is not in the same direction (ascending or descending).

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:

Mismatched bus ordering on <NetName> Low value first and High value first

where:

  • NetName is the name of the parent net to which the mismatched bus ordering is associated.

Recommendation for Resolution

With the violation selected in the Messages panel, use the Details region of the panel to quickly trace the affected bus slice and identify the net identifiers (port, net label, sheet entry, etc.,) whose bus ordering is not consistent. Determine the correct ordering and amend the naming for the erroneous 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).
