tx_layer

The cut layer on which the constraint is applied.

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

g_spacing

The spacing between the cut shapes must be greater than or equal to this value.

'groupName t_groupName

The constraint applies to the specified via group.

'cutClass {f_cutWidth | (f_cutWidth f_cutLength) | t_name}

The constraint applies to the cut class 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

'numCuts x_numCuts

The constraint applies only if the number of via cuts in the group is exactly this value.

'prl f_prl

This parameter, with within, forms the search window for otherCutClass.

Type: Floating-point values specifying a range of parallel run lengths

'within f_within

This parameter, with prl, forms the search window for otherCutClass.

'otherCutClass {f_cutWidth | (f_cutWidth f_cutLength) | t_name}

The constraint applies only if any cut of the via group specified by groupName overlaps the search window of a cut of this cut class, which is specified by width, by width and length, or by name (as defined in a cutClasses constraint).

• f_cutWidth: Width
• f_cutLength: Length
• t_name: Name of the cut class

'sameMask | 'diffMask

The mask type. If mask type is not specified, the constraint applies to all cuts on the layer.

• 'sameMask: The constraint applies only on cuts with the same mask.
• 'diffMask: (ICADVM20.1 Only – 95511 and 95800) The constraint applies only to via cuts on different masks.

Type: Boolean

'horizontal | 'vertical ['cutPrl g_cutPrl]

The constraint applies only in the given direction on spacing between two cuts with a parallel run length more than 0 or more than the specified cutPrl value.

'twoSides

(ICADVM20.1 Only – 95511 and 95800) The constraint applies only when there are neighbor cuts on both sides.

'groupToGroup ['noMergedCuts]

The constraint applies only on cuts of different via groups. Cuts of the same group are merged before the spacing is applied.

(ICADVM20.1 Only – 95511 and 95800) noMergedCuts specifies that cuts should not be merged before applying the spacing.

'mergedCuts

(ICADVM20.1 Only – 95511 and 95800) The cut spacing is applied on the bounding box formed around cuts of a group.

'otherLayer g_otherLayer

(ICADVM20.1 Only – 95511 and 95800) The constraint considers the inter-layer cut spacing between a via group on the current layer to a cut on an adjacent cut layer.
