Potential Difference

This DFE rule is used to compare net clearance and capacitor voltage with a voltage standard table.

The designer has to pay attention to stable power supplying more than coupling problem. To do this, power patterns should be apart enough distance from each other. If they are too close, the designer has to reserve hole to make them apart. The rule checks whether two power traces have enough spaces.
  • Net Group: Select a target net group and assign a reference voltage.
  • Check Net to Net Clearance: Select two target net groups and assign a required clearance.
  • Potential Table Import
    • Table File Path: File path of your ASCII text format standard voltage table.
    • Net Property: Specify a net property that appears in the voltage table.
    • No Include Nets in the Table: Upon selecting, the tool tests other signals which are not included in potential table.
    • Component Group: Check if property of net (which connected component) is not described in potential table.
  • Check Component Capacity
    • Component Group: Select a capacitor component group.
    • Capacity Value: Assign a value for the selected components. The tool checks if this value is matched with the capacity in the voltage table.
    • Tolerance: Assign an allowable capacity value as percentage.
