| Applies to version: 15.1
Now reading version 15.1. For the latest, read: Working with the Supply Nets Design Rule on a PCB in Altium Designer for version 21
Rule category: Signal Integrity
Rule classification: Binary
Summary
This rule identifies a supply net and specifies its voltage (or set of nets using the net class scope).
Constraints
Default constraints for the Supply Nets rule.
- Voltage - the voltage value for the net(s) falling under the scope (full query) of the rule.
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
Batch DRC and during Signal Integrity analysis.
Tips
- The supply net(s) can be specified by enabling the Net or Net Class option in the Where the First object matches region of the PCB Rules and Constraints Editor dialog, and choosing the required net or net class from the corresponding drop-down list. The corresponding Full Query for the rules' scope will be as follows: InNet('NetName') - for a single net; InNetClass('NetClassName') - for a net class.
