) ;spacings

Specifies the minimum spacing between two via cuts with a parallel overlap greater than zero and with neighboring wires at a distance less than within, overlapped by a single metal shape that covers the entire length of the common projection between them from above and/or below.

Values

tx_cutLayer	The cut layer on which the constraint is applied. Type: String (layer and purpose names) or Integer (layer number)
f_spacing	The minimum spacing between the via cuts.

Parameters

'within f_within	The neighboring wires must be present at a distance less than this value from the via cuts.
'above	The constraint applies only if the via cuts are overlapped by a same-metal shape from above. Type: Boolean
'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
'exceptTwoEdges	The constraint does not apply if at least one via cut has neighboring wires on opposite edges at a distance less than within from it. Type: Boolean
'numCuts x_numCuts
	The constraint does not apply if there exist at least these many via cuts overlapped by the a single metal shape on the layers above and below.

Examples

• Example 1: minSameMetalSharedEdgeViaSpacing with within and exceptTwoEdges
• Example 2: minSameMetalSharedEdgeViaSpacing with within

Example 1: minSameMetalSharedEdgeViaSpacing with within and exceptTwoEdges

Two via cuts with a parallel overlap greater than zero and neighboring wires at a distance less than 0.12 on the same edge must have a spacing greater than or equal to 0.1.

Example 2: minSameMetalSharedEdgeViaSpacing with within

Two via cuts with a parallel overlap greater than zero and neighboring wires at a distance less than 0.12 must have a spacing greater than or equal to 0.1.
