Differential Pair

How to find the maximum uncoupled length in differential pairs? Please Help me to find the correct answer.

Initially set the max uncoupled length to 0mm, run DRC and check the error messages - they will tell you exactly what is the uncoupled length in which signals.

PS: Then, you may want to find the longest uncoupled length in the error messages, go back to this rule and set the max uncoupled length to a little bit larger number. This way you will not be getting the error messages anymore.
