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

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.
