minRedundantViaSetback

Specifies the metal enclosure required on a metal layer when redundant vias are aligned on the same edge of that metal layer.

minRedundantViaSetback Quick Reference

Value Type

minRedundantViaSetback constraints have a OneDTblValue. The lookup key (width) represents the width of the wide metal and the value for the table represents the redundant via wide enclosure width in user units. Layer1 is the cut layer and layer2 is the metal layer.

Parameters

• distanceMeasureType (IntValue, optional) specifies the spacing measurement method as Euclidean (0, default) or Manhattan (1). For information on this parameter, see Euclidean and Manhattan Spacing Constraints.
