Specifies the minimum area for rectangular shapes on a layer. Optionally, you can also specify a minimum and maximum width for the shape beyond which the constraint does not apply.

To specify the minimum area for non-rectangular, polygonal shapes, use the minArea constraint.

Examples

Example 1: oaMinRectArea

Sets the minimum rectangular area for a shape on Metal1 to 5.0 user units².

set_layer_constraint -constraint oaMinRectArea -layer Metal1 -AreaValue 5.0

Example 2: oaMinRectArea with width and maxWidth

Sets the minimum rectangular area for a shape on Metal1 to 0.08 user units² if the width of the shape is greater than or equal to 0.4 and less than or equal to 0.5.

set_constraint_parameter -name width -Value 0.4
set_constraint_parameter -name maxWidth -Value 0.5
set_layer_constraint -layer Metal1 -constraint oaMinRectArea -AreaValue 0.08
