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 (with I/O Type Output or IO) or a sheet entry (with I/O Type Input or Bidirectional) is not connected to another part of the circuit (e.g., pin, port, sheet entry, power port, offsheet connector).

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:

Signal <SignalName> has no load

where:

  • SignalName is the name of the affected signal.

Recommendation for Resolution

If the offending pin or sheet entry is intended to be used within the design, ensure that it is connected to the relevant point in the circuit.

If the offending object is a component pin and you do not intend to use it within the design, place a No ERC directive on the pin.

If the offending object is a sheet entry that you do not intend to use, remove it from its parent sheet symbol.

Tips

  1. This violation type will only be displayed when compiling a free schematic document.
  2. 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).
