The built-in layer constraint definition oacMinDiffPotentialSpacing determines the distance required between two objects at different voltage levels that are on the same layer. The distance is specified in database units.
This constraint typically applies to wells, transistors, and devices that are at different voltage levels.
Constraint type: | oaLayerConstraint |
Value types: | oaIntValue |
Database types: | oaDesign, oaTech |
Object types: | oaAppObject |
The following value types are supported by this constraint:
This oaIntValue represents the minimum spacing in database units required between the two geometries.
Units: DBU
When two geometries, typically two NWell shapes, are at different potentials, a larger spacing is required between the two geometries. The larger spacing prevents potential leakage problems through the substrate.
