The minimum spacing required for wires of different voltages in the given routing layer to all cut via shapes in the adjacent cut layers above and below where the metal shape is at greater than or equal to the given voltage.
| Constraint type: | oaLayerPairConstraint (Symmetric: yes) |
| Value types: | oaValueArrayValue |
| Database types: | oaDesign, oaTech |
| Object types: | oaAppObject |
The following value types are supported by this constraint:
The constraint value consists of float-Int pairs where voltage is represented as a float and the clearance value is represented as an integer in database units. The voltage index represents the maximum voltage difference between the two shapes. The voltage value would have a >= semantic, that specifies the required clearance which applies to all voltage differences greater than or equal to it. Please refer to the example section for a detailed description.
