minTouchingDirectionClearance

Specifies the minimum required clearance between layer1 and layer2 in the direction normal to the layer1 edge when that edge is touched by a third layer. Touching is defined as either abutting of the third layer with layer1 or overlapping of layer1 by the third layer. The clearance is measured between the layer1 edge that touches the third layer and adjacent layer2 shapes.

Use this constraint to specify the clearance between poly and gate in the direction of the channel.

Value Types

minTouchingDirectionClearance constraints have a

• Value specifies the clearance in user units.
• DualValue specifies the clearance when the spacing measurement method is set to Manhattan. The first number of the pair describes the required clearance in the direction normal to the touching edge and the second number describes the required clearance parallel to the touching edge.

Parameters

• distanceMeasureType (IntValue, optional) specifies the spacing measurement method as either Euclidean (0, default) or Manhattan (1).
