Differential Pairs - Rules

In AD14 Differential Pairs width and gap rules are combined.

"Improvements to the differential pair rule definition, the ability to cycle the width-gap setting, and support for room-based rule scoping were added in Altium Designer 14."

Rule Definition for Differential Pair Routing - Altium   

 In AD14 Width and Gap are set up in a single rule.



 In AD13 Width and Gap are set up using a Differential Pair rule and a Trace width rule.

AD13 Width rule for Differential Pair

Matched Length Rules are the same in AD13 or AD14.


Tip: For Forward and Backward compatibility you can leave the AD13 rules in a design and update the new AD14 Differential Pair Rule using the sittings found in the two AD13 rules.
