) ;orderedSpacings

(Virtuoso Advanced Node for Layout Standard) Specifies the layer1 edges that must coincide with a layer2 edge.

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)

Parameters

`'horizontalEdge \| 'verticalEdge`
	The constraint applies only to layer1 edges that are in this direction. Type: Boolean
`'edgeLengthRanges (`g_ranges`)`
	The constraint applies only if the layer1 edge length is in this range. Type: Floating-point values specifying the length ranges to which the constraint applies
`'endOfLineOnly`	The constraint applies only if the layer1 edge is between two convex corners and its length falls in the range specified with `'edgeLengthRanges`. Type: Boolean

Example

Horizontal Metal1 edges between two convex corners must coincide with a Metal2 edge if the edge length is less than 0.02 or greater than 0.03 and less than 0.04.
