This constraint defines the minimum spacing between two shapes on the same layer where the maximum span length of both shapes is greater than the defined span length and the parallel run length of each span section is greater than the defined parallel run length between shapes.
| Constraint type: | oaLayerConstraint |
| Value types: | oaInt2DTblValue |
| Database types: | oaDesign, oaTech |
| Object types: | oaAppObject |
The following value types are supported by this constraint:
A 2D table specifying the required parallel span spacing. A NxN 2D table is used that implicitly has the same span lengths for the row and column headings. The spanLength values must be increasing from top to bottom in the table. The spacing values must be the same or increasing from left to right, and from top to bottom in the table. The table rows are indexed by spanLength1, the columns are indexed by spanLength2.
Units: DBU
The following parameters are supported by this constraint:
| Name | Value Type | Units | Default | Description |
|---|---|---|---|---|
| length oacLengthConstraintParamType |
oaIntValue | DBU | None |
The constraint only applies if the parallel run length is > this value. The parallel run length is measured as a continuous summed length among the objects, but turning corners would break up the parallel run length calculation into pieces. |
