Working with the Signal Base Value Design Rule on a PCB in Altium Designer

Rule category: Signal Integrity

Rule classification: Unary

Summary

This rule specifies the maximum voltage level that a signal can settle to in the low state (the base value).

Constraints

Default constraints for the Signal Base Value rule.

• Maximum (Volts) - the value for the maximum permissible base value voltage.

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.
