Rule category: Manufacturing
Rule classification: Unary
Summary
This rule operates at a net level in the design to flag any open-ended track/arc primitive, or open-ended track/arc that is terminated with a via, and thus forms an antenna.
Constraints
Default constraint for the Net Antennae rule.
- Net Antennae Tolerance - maximum permissible length for the stub of an open-ended track/arc primitive (or one that terminates in a via).
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.
