Applies to Altium Designer versions: 15.1, 16.0, 16.1, 17.0 and 17.1
 

Parent category: Violations Associated with Nets

Default report mode:

Summary

This violation appears when a differential pair net is not properly connected to a differential pair pin of a physical device.

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. A notification is also displayed in the Messages panel in the following format:

Misconnected differential pair <PairName>: net <NetName> should be connected to pin <PinDesignator>

where:

  • PairName is the name of the differential pair (e.g. V_TX1)
  • NetName is the name of the positive or negative polarity net in the pair (e.g. V_TX1_N or V_TX1_P)
  • PinDesignator is the designator of the device pin to which the offending net should be connecting (e.g. E6)

Recommendation for Resolution

This type of violation typically arises when the wire object for the differential pair net is not making electrical connection with the target pin of the device. Use the Details region of the Messages panel to quickly cross probe to the device pin and ensure proper connection between the wire of the net and the pin itself.
