minDensityHole

Specifies the minimum effective width and minimum area for a hole on a layer. Holes that meet the given criteria can be identified using check_density and annotated for review. create_fill can be used to increase metal density in the holes by adding fill shapes.

Value Type

minDensityHole constraints have a Value that represents the minimum area for holes on the layer.

Parameter

• width (Value) specifies the minimum effective width for holes on the layer. This parameter is required.

Examples

This example identifies holes on Metal2 that are at least 1.5 user units in width and at least 10 user units² in area.

set_constraint_parameter -name width -Value 1.5
set_layer_constraint -layer Metal2 -constraint minDensityHole -Value 10
