Maximum parallel trace length Limit the length that signal traces run parallel to each other to reduce coupling and crosstalk. This is especially crucial for high-speed differential pairs. The acceptable length depends on factors like trace spacing, layer stack-up, and signal frequency. So the values below are just examples. We set the allowed Max parallel traces for two situations for this Constraint Set. The Rule immediately applies in the Constraint Manager and the design adheres to the rule. 46 www.cadence.com OrCAD X Constraint Management Guide
