This document is no longer available beyond version 4. Information can now be found here: Unconnected objects in net for version 5

This documentation page references Altium NEXUS/NEXUS Client (part of the deployed NEXUS solution), which has been discontinued. All your PCB design, data management and collaboration needs can now be delivered by Altium Designer and a connected Altium 365 Workspace. Check out the FAQs page for more information.

 

Parent category: Violations Associated with Nets

Default report mode:

Summary

This violation occurs when a pin, port, or sheet entry object is not wired up 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:

Unconnected <Object> at <Location>

where:

  • Object is the type and name of the offending object (pin, port, or sheet entry).
  • Location is the X,Y coordinates of the object on the source schematic sheet.

Recommendation for Resolution

Consider the following in order to resolve this error:

  • If the pin/port/sheet entry is to be used, ensure that it is wired up to the rest of the circuit accordingly.
  • If a port or sheet entry is redundant, remove it from the design.
  • Tie any unused input pins to the appropriate power line.
  • Place No ERC directives on unused input or output pins.

Tips

  1. When the unconnected object is an input pin, an additional violation message will appear alerting you to the fact that the net to which the pin is associated contains floating input pins. The identifier for the pin will be listed in that message.
  2. The actual report mode used for a violation of this type is dependent on the specific object type, its electrical I/O type, and the corresponding reporting level defined on the Connection Matrix tab of the Options for Project dialog (Project » Project Options).
  3. The Report Mode setting on the Error Reporting tab of the Options for Project dialog has no affect on the Report Mode setting that appears for a violation of this type in the Messages panel. It is, however, used by the Online (real-time) error reporting, directly within the design workspace. Controls for the Online reporting are available on the Schematic - Compiler page of the Preferences dialog.
  4. 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).
