The built-in oacMinParallelViaClearance layerArray constraint specifies the clearance between cut shapes on one layer with respect to cut shapes on an adjacent layer that have parallel edges with an overlap greater than 0. This constraint applies only when the cuts do not share the same metal shape on the layer between them.
This constraint is an oaLayerArrayConstraint type, where the first two layers in the array are the cut layers, and the third is the layer between the two cut layers.
| Constraint type: | oaLayerArrayConstraint (Number of layers: 3) |
| Value types: | oaIntValue |
| Database types: | oaDesign, oaTech |
| Object types: | oaAppObject |
The following value types are supported by this constraint:
This oaIntValue represents the clearance value in database units.
