Mismatched Bus Label Ordering – Несовпадающие направления меток шины
This document is no longer available beyond version 21.0. Information can now be found here: Mismatched bus label ordering for version 24
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).
