Parent category: Violations Associated with Nets
Default report mode:
This violation occurs when the same polarity net (positive or negative) has been detected in multiple differential pair objects within the 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. AA notification is also displayed in the Messages panel in the following format:
Net <NetName> is used in more than one differential pair objects: <ObjectList>
where:
This violation typically arises when the same net label has been attached to multiple wire objects upon which differential pair directives have also been attached. Locate the offending net label objects (use the Details region of the Messages panel to cross-probe to the relevant area of the source schematic document) and amend the names as required.
The positive and negative wires in a pairing should have associated net labels with the same root name for the net, along with a _P and _N suffix respectively. For example, if two wires in a particular pair have the same net label, V_RX1_N, change the positive wire's net label to V_RX1_P.
