Specifies the minimum extension of an end-of-line edge of a layer1 shape past a layer2 shape when three parallel layer1 edges are present on three sides of the enclosing layer1 shape at a distance less than or equal to the specified values.
Values
|
tx_layer1
|
The first layer on which the constraint is applied. The shape on this layer encloses a shape on tx_layer2.
Type: String (layer and purpose names) or Integer (layer number)
|
|
tx_layer2
|
The second layer on which the constraint is applied. The shape on this layer is enclosed.
Type: String (layer and purpose names) or Integer (layer number)
|
|
f_extension
|
The extension of an end-of-line edge past a cut edge must be greater than or equal to this value.
|
Parameters
|
f_eolWidth
|
|
|
The constraint applies only if the end-of-line width is less than this value.
|
|
f_eolSpace f_eolWithin
|
|
|
These two parameters together define a verification region that extends beyond and on both sides of the end-of-line edge up to a distance equal to eolSpace and eolWithin, respectively. The constraint applies only if a layer1 neighboring edge is present inside this verification region (and inside the verification regions defined by parWithin and parSpace).
|
|
f_parWithin f_parSpace
|
|
|
These two parameters together define verification regions on either side of the enclosing layer1 shape. The verification regions extend up to a distance equal to parWithin along the length of the enclosing layer1 shape and equal to parSpace on both sides of the end-of-line edge. The constraint applies only if a layer1 edge is present inside both verification regions (and inside the verification region defined by eolSpace and eolWithin).

Example
The extension of a Metal1 end-of-line edge past a Via1 cut edge must be greater than or equal to "extension" if three parallel Metal1 edges are present on three sides of the enclosing Metal1 shape.
