Component to Net Clearance
This rule checks for component clearance violations when routed traces may affect the performance of nearby components.
- Item: Input item name.
- Net: Select a target net group.
- Component: Select a target component group.
- Except Comp Connected: DFE checks the distance between components in the component group and nets that are not connected to any components in the selected component group.
- Except Nets: Specify nets can be excluded from distance checking
- Clearance: Assign a distance or clearance and select target layer(s).
- Component2: Assign component group If component2 is placed at the same position of component1. (Example: Power TR and Heat-Sink)
- Comp2 Distance: Enter the value the component should be located within specific distance from component1. (DFE selects target component2 among component2 group components which is located within this distance.)
- Comp2 Area: Assign base check range of component2. (Silk+Pad, Pad, COC)
