This constraint specifies the gate extension if a layer1 (poly) shape is within specific distance of an L-shape of the same MOS layer2 (oxide) shape.
| Constraint type: | oaLayerPairConstraint (Symmetric: no) |
| Value types: | oaIntValue |
| Database types: | oaDesign, oaTech |
| Object types: | oaAppObject |
The following value types are supported by this constraint:
This value is the required minimum extension.
Units: DBU
The following parameters are supported by this constraint:
| Name | Value Type | Units | Default | Description |
|---|---|---|---|---|
| distance oacDistanceConstraintParamType |
oaIntValue | DBU | None |
This parameter holds the spacing value. The constraint would only apply if the spacing between the two layers is < than the parameter value. |
| minJogLength oacMinJogLengthConstraintParamType |
oaIntValue | DBU | None |
This parameter holds the value of the maximum allowed jog up until which the rule does not apply. The rule would not apply if the oxide jog is =< this parameter value. |
This constraint ensures sufficient poly overhang past gate forming connections.
