Rule category: SMT
Rule classification: Unary
Summary
This rule specifies the maximum routing length from the center of a surface mount pad to the center of the pad/via connecting to a power plane.
Constraints
Default constraints for the SMD To Plane rule.
- Distance - the value for the maximum permissible distance from SMD pad to pad/via connecting to the power plane.
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 and Batch DRC.
