Parent category: Violations Associated with Nets

Default report mode:

Summary

This violation occurs when a pin (with I/O Type Input or IO) or a sheet entry (with I/O Type Input or Bidirectional) is connected to multiple driving pins or ports on the schematic sheet.

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 multiple drivers

where:

  • SignalName is the name of the affected signal.

Recommendation for Resolution

With the violation selected in the Messages panel, use the Details region of the panel to cross-probe to the affected signal pins/sheet entries. Trace the wiring from the pin/sheet entry to ensure it is connected as required and modify if it is not.

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).
