 -layer cutLayer -Value viaWidth}

ARRAYSPACING WIDTH viaWidth

spacings(
( minLargeViaArrayWidth cutLayer viaWidth )
)

Parameters

• cutClass (DualValue, optional) The constraint applies only to the cut class of the given dimensions.
• parallelOverlap (BoolValue, optional) The constraint applies only when there is a parallel edge overlap > 0.
