(Virtuoso Layout Suite EXL and higher tiers) Specifies a keepout region against a cut if the following conditions are met:
-
The cut does not touch or overlap with the region if it is in a wire with width less than or equal to the specified value and with mask different from the mask of the end-of-line.
-
A same-mask neighbor wire has an extension overlapping with the region.
Values
|
tx_metal
|
The metal layer on which the constraint is applied.
Type: String (layer and purpose names) or Integer (layer number)
|
|
tx_cut
|
The cut layer on which the constraint is applied.
Type: String (layer and purpose names) or Integer (layer number)
|
|
f_backwardExt f_sideExt f_forwardExt
|
|
|
The amount of extension from the corners of the end-of-line edge:
-
f_backwardExt indicates extension in the backward direction.
-
f_sideExt indicates extension to the side.
-
f_forwardExt indicates extension in the forward direction.
|
Parameters
|
'minEolWidth f_minEolWidth
|
|
|
The constraint applies when the end-of-line has width less than this value.
|
|
'mask1 | 'mask2 | 'mask3
|
|
|
The constraint applies when the end-of-line shape is on the specified mask.
|
|
'otherWidth f_otherWidth
|
|
|
The constraint applies to different-mask wires that have width less than or equal to this value and a cut that overlaps or touches the keepout region.
|
|
'otherExtension f_otherExtension
|
|
|
The constraint applies when there is a same-mask neighbor wire with the specified extension value at the end-of-line overlapping the keepout region.
|
|
'exceptBackSideAligned
|
|
|
The constraint does not apply if the neighbor wire is aligned to the end-of-line from the back.
|
Example
Specifies a keepout region between Metal1 and Via1 if the specified conditions are met, except when the neighbor wire is aligned to the end-of-line from the back.
