(Virtuoso Layout Suite EXL and higher tiers) Specifies the layer on which overlap is not allowed.

tx_layer

The layer on which the constraint is applied.

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

`'overlapLayer` tx_overlapLayer
	The layer on which overlaps are not allowed. Type: String (layer name) or Integer (layer number)
`'overlapPurpose` tx_overlapPurpose
	The purpose on which overlaps are not allowed.
`'maxVoltage` f_maxVoltage
	The constraint applies only if the voltage on the specified layer shape is greater than this value.
