(Virtuoso Advanced Node for Layout Standard) Specifies the minimum width and length for a protrusion on a wide wire. The length of the protrusion varies based on the width of the wide wire. The constraint applies only if the protrusion contains a single via cut of the specified cut class.

Values

tx_metalLayer

The metal layer on which the constraint is applied.

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

tx_cutLayer

The cut layer on which the constraint is applied.

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

f_width

The width of the protrusion must be greater than or equal to this value.

Parameters

`'widthLengthTable (`f_wideWidth f_length`)`
	If the width of the wide wire on which the protrusion exists is greater than or equal to wideWidth, the length of the protrusion must be greater than or equal to length.
`'cutClass {`f_width `\| (f_width` f_length`) \|` t_name`}`
	The cut class to which the constraint applies, specified by width, by width and length, or by name (as defined in a cutClasses constraint). f_width: Width f_length: Length t_name: Name of the cut class The constraint applies only if the protrusion contains a single via cut of this cut class.

Example

If the protrusion on a wide Metal1 wire contains a single via cut of type VA on Via1, the following conditions must be met:

The width of the protrusion must be at least 0.05.
If the width of the wide wire is greater than or equal to 0.11, the length of the protrusion must be at least 0.12.
