(Virtuoso Advanced Node for Layout Only) Specifies that a wire must not overlap with the search region formed by eolWithin—measured along the end-of-line edge of the middle wire of a group of five wires—and eolSpacing—measured orthogonal to the end-of-line edge—provided the following conditions are true:

• Each wire in the group of five wires has width equal to width and each wire in the group is spaced paraEdgeSpacing apart, with common parallel run length greater than prl.
• The via cut enclosed by the middle wire is at a distance less than cutWithin from the group of five wires, the distance measured beyond the common parallel run length.
• The distance of the via cut from the end-of-line edge of the middle wire is less than enclosedDistance.
• No wire completely overlaps the two search regions, including touching, formed by sideExt (measured along the end-of-line edge) and forwardExt (measured orthogonal to the end-of-line edge), in the orthogonal direction.
  
  

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_eolSpacing	The minimum spacing required between the end-of-line edges of the middle wire containing the via and a neighboring wire.

Parameters

'width f_width
	The constraint applies only if the width of each of the five wires is equal to this value.
'parallelEdgeSpace f_paraEdgeSpacing
	The constraint applies only if the spacing between each pair of adjacent wires in the set of five wires is equal to this value.
'distance f_eolWithin
	The end-of-line edge of the middle wire containing the via cut is extended by this value on both sides when searching for a neighboring wire beyond the end-of-line edge. This parameter together with the constraint value (eolSpacing) forms a search window. A violation occurs if a wire overlaps this search window when all required conditions are met.
'enclosedDistance f_enclosedDistance
	The constraint applies only if the via cut is at a distance less than this value from the end-of-line edge of the middle wire.
'cutDistance f_cutDistance
	The constraint applies only if the via cut is at a distance less than this value from the group of five wires with common parallel run length greater than prl.
'prl f_prl
	The constraint applies only if the five wires have common parallel run length greater than this value.
'noMetalEolExtension (f_sideExt f_forwardExt)
	The two values, sideExt (measured along the end-of-line edge) and forwardExt (measured orthogonal to the end-of-line edge), together define two additional search regions on either side of the middle wire. The constraint applies only if no wire completely overlaps any of these search regions, including touching, in the orthogonal direction.

Example

A neighboring wire must not overlap a search region that extends 0.02 on either side of the end-of-line edge of the middle wire (of a set of five wires) and 0.1 in the direction orthogonal to it if all of the following conditions are true:

• The width of each wire in the set is 0.04 and the wires are spaced 0.04 apart, with common parallel run length greater than 0.14.
• The middle wire contains a via cut that is at a distance less than 0.03 from the end-of-line edge of the wire and at a distance less than 0.13 measured beyond the common parallel run length of the group of wires.
• No wire overlaps the search regions formed by the value pair (0.15, 0.08).
