Inductance
This DFE rule is to check the trace length from passive component to GND.
The usage guide for decoupling capacitors is that they should be placed within
certain distance from a certain component’s power pin and connecting should be
shorter than the given length. Long routing length between component power pin and
decoupling capacitor causes increase of inductance element and causes bad SSN
noise.
- Item: Enter item name.
- POWER Net: Select a power net group that is connected to passive component.
- GND Net: Select a ground net group that is connected to passive component.
- Passive Comp: Select a target passive component group.
- Start Comp: Select a target component group.
- Length to Plane/Via: Assign trace length criteria between passive component pin and Ground.
