) ;orderedSpacings

(Virtuoso Advanced Node for Layout Standard) Specifies the minimum spacing required between the corners of shapes on the specified layers.

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)

g_spacing

The minimum spacing between the corners of shapes on the specified layers.

Parameters

`'allCorner \| 'concaveCorner \| 'convexCorner`
	The constraint applies to corners of this type on layer1. Type: Boolean
`'otherAllCorner \| 'otherConcaveCorner \| 'otherConvexCorner`
	The constraint applies to corners of this type on layer2. Type: Boolean
`'deltaVoltage` f_deltav
	The constraint applies if the maximum voltage difference between the two shapes is greater than this value.

Example

The spacing between Metal1 and Metal2 corners must be greater than or equal to 0.5 if the following conditions are met:

The Metal1 corner is concave.
The Metal2 corner is concave or convex.
The maximum voltage difference between Metal1 and Metal2 shapes is greater than 0.8V.
