Nexus message

This documentation page references Altium NEXUS/NEXUS Client (part of the deployed NEXUS solution), which has been discontinued. All your PCB design, data management and collaboration needs can now be delivered by Altium Designer and a connected Altium 365 Workspace. Check out the FAQs page for more information.

 

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 Defining, Scoping & Managing PCB 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.
