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
- 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.
