Parent category: Violations Associated with Nets

Default report mode: 

Summary

This violation occurs when a net label has been detected to be floating, i.e. not attached to a wire or bus object, within the design. The message will also appear for a bus power port object that is not electrically connected to the rest of the circuit.

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:

Floating Net Label <NetLabelName>

where:

  • NetLabelName is the name of the offending net label.

Recommendation for Resolution

Ensure that the offending net label object is connected to the required wire or bus object. If the net label is redundant, delete it from the design.

Check also that the wire/bus object and associated net label are on grid. An object can be moved back onto grid manually or by using the Edit » Align » Align To Grid command.

Also check that a wire is really a wire and not a line 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). 
Note

The features available depend on your level of Altium Designer Software Subscription.
