minNeighborViaSpacing

Specifies the minimum spacing between two shapes on a given cut layer that have a common neighboring cut shape within a given distance. The distance and spacing is optionally measured from center-to-center of the cut shapes. By default, the distance and spacing are measured from nearest cut edge-to-cut edge.

minNeighborViaSpacing Quick Reference

Value Type

minNeighborViaSpacing constraints have a Value that represents the minimum spacing between the two shapes on the cut layer.

Parameters

• distanceWithin (Value, required) specifies that the constraint applies only when a common neighbor via is less than or equal to this distance from the two cut shapes.
• oaCenterToCenter (BoolValue, optional) determines whether the spacing and distance are measured center-to-center (true) or edge-to-edge (false, default).

Examples

This example requires a 0.4 neighbor via spacing if a common neighbor via is within 0.3 user units measured center-to-center.

set_constraint_parameter -name centerToCenter -BoolValue true
set_constraint_parameter -name distanceWithin -Value 0.3
