The built-in oacMinEndOfNotchSpacing layer constraint specifies the minimum spacing between the notch and shapes overlapping within the extent of the notch. This constraint is dependent on three parameters: minNotchSpacing, minNotchLength, and endOfNotchWidth. The constraint applies if the notch width is less than endOfNotchWidth, the notch spacing is less than or equal to minNotchSpacing, and the notch length is greater than or equal to minNotchLength.
The intended usage is for minNotchSpacing and the spacing constraint value to be only slightly larger than the normal minimum spacing constraint (between one and two times the minSpacing constraint) and the endOfNotchWidth to be only slightly larger than the minimum width constraint (between one and two times the minWidth constraint).
| Constraint type: | oaLayerConstraint |
| Value types: | oaIntValue |

The following value types are supported by this constraint:
oacMinEndOfNotchSpacing is an oaIntValue.
Units: DBU
The following parameters are supported by this constraint:
| Name | Value Type | Units | Default | Description |
|---|---|---|---|---|
| oaNotchLength oacNotchLengthConstraintParamType |
oaIntValue | DBU | (Required) |
The constraint applies if the notch length is greater than or equal to minNotchLength and other parameters also have the required values. |
| oaNotchSpacing oacNotchSpacingConstraintParamType |
oaIntValue | DBU | (Required) |
The constraint applies if the notch spacing is less than or equal to minNotchSpacing and other parameters also have the required values. |
| oaNotchWidth oacNotchWidthConstraintParamType |
oaIntValue | DBU | (Required) |
The constraint applies if the notch width is less than endOfNotchWidth and other parameters also have the required values. |
