This rule checks for component clearance violations when routed traces may affect the
performance of nearby components.
When there are routed traces near a certain component such as OSC or transformers,
the traces may affect the performance of the component. High power components may
also affect nearby signal nets by heat generated from them. For this reason, certain
components require a gap or clearance to nearest traces or other routed geometry.
This rule checks for such clearance violations.
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)
High power components may also affect nearby signal nets by heat generated from
them. Figure 1.
