Specifies that shapes connected to form an H-shaped pattern on the same layer (layer1) cause a violation if any of the following conditions is true:

• The width of the rails (W) is less than the specified width (width).
• The extension of the rails (X) from the connecting shape is greater than the specified extension (length).
• The distance between the rails (U) is less than the specified distance (distance).
• The width (V) of the center shape is less than the specified constraint value (centerShapeWidth).
  
  

Values

tx_layer1	The first layer on which the constraint is applied. Type: String (layer and purpose names) or Integer (layer number)
tx_layer2	The second layer on which the constraint is applied. Type: String (layer and purpose names) or Integer (layer number)
f_centerShapeWidth
	The width of the center shape must be greater than or equal to this value.

Parameters

'width f_width
	The width of the rails must be greater than or equal to this value.
'length f_length
	The extension of the rails from the connecting shape must be less than or equal to this value.
'within f_distance
	The distance between the rails must be greater than or equal to this value.

Example

If shapes are connected to form an H-shaped pattern on Metal1, the width of the rails must be greater than or equal to 0.3, the extension of the rails from the connecting shape must be less than or equal to 0.9, the distance between the rails must be greater than or equal to 0.5, and the width of the center shape must be greater than or equal to 0.5.
