minInsideCornerEdgeLength

spacings(
( minInsideCornerEdgeLength tx_layer 
 {f_edgeLength | (f_lengthSum f_edgeLength)} 
)

) ;spacings

Sets the minimum length of an edge that is in a concave corner of a shape.

The figure below illustrates a concave shape because the two green edges that are greater than or equal to edgeLength long abut consecutive edges (in pink) shorter than the minimum edge length.

Values

tx_layer	The layer on which the constraint is applied. Type: String (layer and purpose names) or Integer (layer number)
f_edgeLength	The edges in a concave corner must be greater than or equal to this value.

Parameters

f_lengthSum

The constraint does not apply if the sum of the consecutive edges that are shorter than edgeLength is less than this value.

Example

The minimum inside corner edge length on Poly1 and Metal2 must be 1.5. The constraint does not apply on Metal2 if the sum of lengths of the consecutive edges that are shorter than 1.5 is less than 5.0.

spacings(    
    ( minInsideCornerEdgeLength "Poly1" 1.5 )
    ( minInsideCornerEdgeLength "Metal2" (5.0 1.5) )
