Group

spacings( 
( cpodeGroup tx_layer 
 'prl g_parallelRunLength
 'parallelWithin g_parallelWithin
 g_cpodeNum
)
); spacings

(Virtuoso Layout Suite EXL and higher tiers) Specifies that maximum g_cpodeNum CPODE shapes with PRL greater than or equal to the value specified in the g_parallelRunLength parameter and within the g_parallelWithin parameter forms a CPODE group.

Values

tx_layer

The layer on which the constraint is applied.

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

g_cpodeNum

The maximum number of shapes that form a CPODE group. If zero is specified, two or more shapes form a group.

Parameters

'prl g_parallelRunLength

Specifies that CPODE shapes with PRL greater than or equal to the specified value and within the value in parallelWithin can form a group.

'parallelWithin g_parallelWithin

Specifies that CPODE shapes with PRL greater than or equal to the specified value in parallelRunLength and within the specified value can form a group.

Example

spacings(
(cpodeGroup "Cpode" 'prl 0.5 'parallelWithin 0.07 4)
) ;spacings
