) ;spacings

Specifies the cut class that is allowed on the given layer.

This constraint should be used in a net's default constraint group, and not in the foundry constraint group.

tx_cutLayer

The cut layer on which the constraint is applied.

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

(f_width f_length) | t_name

The cut class allowed for the specified layer, specified by width and length or by name (as defined in a cutClasses constraint).

`'rowCol (`x_row x_col`)`
	The number of rows and columns in a multiple-cut via of the specified cut class must be equal to row and col, respectively.

The cuts in a 0.3x0.3 via on layer Via1 must be organized into 2x2 array.
