Parent category: Violations Associated with Nets

Default report mode:


This violation occurs when a wire object is detected to be floating, i.e. not electrically connected to any part of the circuit design.


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:

Unconnected line <Location1> To <Location2>


  • Location1 is the X,Y coordinates for the start point of the floating wire.
  • Location2 is the X,Y coordinates for the end point of the floating wire.

Recommendation for Resolution

Ensure that the offending wire object is connected into the circuit as required. If the wire is redundant, delete it from the design. If the wire (or any other object) is off the sheet and cannot be directly selected, use the Edit » Select » Outside Area command to select it, then delete it.


  • 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).
