minLength

spacings(
( minLength tx_layer
['width f_width]
['exceptViaLayers (tx_viaLayer1 tx_viaLayer2 ... tx_viaLayerN)]
f_length )
) ;spacings

Determines the minimum orthogonal length for a shape on the specified layer.

Values

tx_layer

The layer on which the constraint is applied.

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

f_length

The length of the shape must be greater than or equal to this value.

Parameters

'width f_width

(Virtuoso Layout Suite EXL and higher tiers) The constraint applies only when the width of the shape is less than or equal to this value.

'exceptViaLayers tx_viaLayer1 tx_viaLayer2 ...tx_viaLayerN

  

(Virtuoso Layout Suite EXL and higher tiers) The constraint applies only when there is no cut on the specified via layers.

Type: String (layer name) or Integer (layer number); Float

Example

The minimum orthogonal length for a shape on Metal1 must be 0.3.
