minSideClearance

Specifies the clearance between the shapes on different layers for a given (short or long) edge.

minSideClearance Quick Reference

Value Type

minSideClearance constraint has the following value type:

• Value specifies the minimum clearance between the edges of the two shapes.

Parameters

• spacingType (IntValue, required) specifies the type of edges of both the shapes.
  
  spacingType Values

  spacingType	Integer Value
  anySideToAnySide	0
  shortSideToShortSide	1
  shortSideToLongSide	2
  shortSideToAnySide	3
  longSideToLongSide	4
  longSideToAnySide	5

• parallelRunLength (Value, optional) specifies that the constraint applies only if the parallel run length between the edges of the shapes is equal to or greater than this value.
  
  This constraint supports negative parallel run length.
• widthRangeArray (RangeArrayValue, optional) specifies that the constraint applies if width of the layer1 shape is in this range.
• otherWidthRangeArray (RangeArrayValue, optional) specifies that the constraint applies if width of the layer2 shape is in this range.

Examples

In this example, the minimum clearance between Metal1 and Metal2 shapes must be greater than or equal to 1.5µm under the following conditions:

• The spacing is measured from any side of the Metal1 shape to any side of the Metal2 shape.
• The parallel run length between the two shapes is greater than or equal to 0.1µm.
• The width of the Metal1 shape is greater than 0.2µm and less than 0.9µm.
• The width of the Metal2 shape is greater than 0.2µm and less than 0.9 µm.
