Working with the Layer Pairs Design Rule on a PCB in Altium Designer
This document is no longer available beyond version 21.0. Information can now be found here: Layer Pairs Rule for version 25
Rule category: Manufacturing
Rule classification: Unary
Summary
This rule checks to ensure that the used via types match the currently defined via types. The used via types are determined from the vias and pads found in the board. The permissible via types are defined on the Via Types tab of the Layer Stack Manager.
Constraints
Default constraint for the Layer Pairs rule.
Enforce layer pairs settings – specifies whether the check is made or not.
How Duplicate Rule Contentions are Resolved
All rules are resolved by the priority setting. The system goes through the rules from highest to lowest priority and picks the first one whose scope expression matches the object(s) being checked.
Rule Application
Online DRC, Batch DRC, and during interactive routing.
