Working with the Net Antennae Design Rule on a PCB in Altium Designer

Created: March 23, 2017 | Updated: March 3, 2020

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.

All design rules are created and managed within the PCB Rules and Constraints Editor dialog. For a high-level view of working with the design rules system, see Constraining the Design - Design Rules. For detailed information regarding how to target the objects that you want a design rule to apply to, see Scoping Design Rules.

Constraints

Default constraint for the Net Antennae rule.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.
