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: Electrical

Rule classification: Binary

Summary

This rule tests for short circuits between primitive objects on the copper (signal and plane) layers. A short circuit exists when two objects that have different net names touch.

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 constraints for the Short-Circuit rule.Default constraints for the Short-Circuit rule.

  • Allow Short Circuit - defines whether the target nets falling under the two scopes (full queries) of the rule can be short-circuited or not. If you require two different nets to be shorted together, for example when connecting two ground systems within a design, ensure that this option is enabled.

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 expressions match the objects being checked.

Rule Application

Online DRC, Batch DRC, and during autorouting.
