shapeRequiredBetweenSpacing

orderedSpacings(
( shapeRequiredBetweenSpacing tx_layer1 tx_layer2
 ['horizontal | 'vertical]
 f_spacing 
)

) ;orderedSpacings

(Virtuoso Advanced Node for Layout Standard) Specifies that shapes on layer1 that are at a distance less than the specified value must have a layer2 shape between them, separating the entire length of the Metal1 shapes.

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_spacing

The constraint applies only if the distance between two layer1 shapes is less than this value.

Parameters

`'horizontal \| 'vertical`
	The direction in which spacing is measured between two layer1 shapes. If direction is not specified, spacing is measured in any direction.

Example

Two Metal1 shapes that are less than 2.0 apart in the horizontal direction must have a Metal2 shape between them, and this Metal2 shape must fully separate the two Metal1 shapes.

)

); spacings

(Virtuoso Layout Suite EXL and higher tiers) Specifies a spacing rule on a six-wire pattern.

Values

tx_layer

The layer on which the constraint is applied.

Type: String (layer and purpose names) or Integer (layer number)

g_spacing

The spacing range value.

Type: Floating-point values specifying a range of spacings that are allowed

Parameters

`'eolSpacing` g_eolSpacing
	The two perfectly aligned wires are less than or equal to the specified value on both of the two sets of middle wires.
`'sameSide \| 'oppositeSide`
	Specifies the side of the two line-ends of the two wires .
`'horizontal \| 'vertical`
	The direction in which the spacing is measured.
`'width` f_width	The width of all of the six wires should be equal to the specified value.
`sideSpacing` f_sideSpacing
	The side-to-side spacing between any two wires in the perpendicular direction in `oaSpacingDirection` should be equal to the specified value.

Example

spacings(
    (cornerEndOfLineKeepout “Metal1”
     'minWidth 0.05 
  'eolSpacing 0.1
  'eolWithin (0.08 0.12) 
  (0.06 0.09))
) ;spacings
