(Virtuoso Advanced Node for Layout Standard) Specifies the maximum cumulative area of all layers that are not connected to the diffusion diode. Optionally, the constraint applies only to a layer range and not to all layers.

Values

f_area

The maximum cumulative area of all layers must be less than or equal to this value. Type: Float value with area units

Parameters

'lowerLayer tx_lowerLayer
	(Virtuoso Layout Suite EXL and higher tiers) The maximum cumulative area is between this layer to the layer specified with upperLayer.
'upperLayer tx_upperLayer
	(Virtuoso Layout Suite EXL and higher tiers) The maximum cumulative area is between the layer specified with lowerLayer to this layer.
'cutLayerOnly	(Virtuoso Layout Suite EXL and higher tiers) Only cut layers are considered when calculating the cumulative area.

Example

The cumulative area of all layers from Metal4 to Metal 5 must be less than or equal to 20000.0.
