) ;spacings

Specifies the minimum spacing required between a convex corner that is formed by filling up a concave corner and a corner of a neighboring shape on a layer.

The concave corner is filled up before mask fabrication, so other shapes on that layer are far enough away from the convex corner that is formed to prevent spacing violations.

The constraint applies only if the following two conditions are satisfied:

• The lengths of the two edges that form the concave corner must be less than length1 and length2.
• The edge with length less than length2 must have an adjacent end-of-line edge with width less than eolWidth.
  
  

Values

tx_layer	The layer on which the constraint is applied. Type: String (layer and purpose names) or Integer (layer number)
f_spacing	The spacing must be greater than or equal to this value.

Parameters

'width f_eolwidth
	The edge of the concave corner with length length2 must have an adjoining end-of-line edge with width less than eolWidth.
'cornerLengths (f_length1 f_length2)
	The constraint applies if the length of one edge of the concave corner is less than length1 and the length of the other edge is less than length2. The edge with length length2 must have an adjoining end-of-line edge with width less than eolWidth.

Example

The spacing between the missing convex corner of a shape and a corner of a neighboring shape must be at least 0.05 if the following conditions are met:

• The length of one concave side is less than 0.06 and the length of the other concave side is less than 0.08.
• The edge adjoining the concave edge with length less than 0.08 is an end-of-line edge with width less than 0.1.
