The oacShapeAngle simple constraint specifies the default geometry orientations that are allowed by the technology. The default orientation applies to all layers in the technology and is designated by a single enumerated type. The orientations that can be set are:
| Constraint type: | oaSimpleConstraint |
| Value types: | oaIntValue |
| Database types: | oaTech |
| Object types: | oaAppObject |
The following value types are supported by this constraint:
oacShapeAngle uses an oaIntValue of type oaShapeAngleType.
Units: Enum
This value is represented by an oaShapeAngleType enumeration:
| Value | Name |
|---|---|
| oacAllShapeAngleType | all |
| oacDiagonalAndOrthogonalShapeAngleType | diagonalAndOrthogonal |
| oacOrthogonalOnlyShapeAngleType | orthogonalOnly |
This constraint sets the default orientation for all layers of the technology. Some CMOS processes limit geometries on certain layers to orthogonal-only orientations. In combination with this constraint, the oacLayerShapeAngle constraint can be used to override the default geometry orientations on certain layers.
