minParallelViaSpacing (Two layers plus metal)
spacings(
( minParallelViaSpacing tx_cutLayer1 tx_cutLayer2 tx_metalLayer
f_spacing
)
) ;spacings
Specifies the minimum edge-to-edge spacing between via cuts on two different layers if the via cuts have parallel edges with an overlap greater than zero. The constraint does not apply if the via cuts share the same metal shape on the layer between the cut layers.
Values
|
tx_cutLayer1
|
The first cut layer on which the constraint is applied.
Type: String (layer and purpose names) or Integer (layer number)
|
|
tx_cutLayer2
|
The second cut layer on which the constraint is applied.
Type: String (layer and purpose names) or Integer (layer number)
|
|
tx_metalLayer
|
The metal layer on which the constraint is applied. The metal layer must be between the two cut layers.
Type: String (layer and purpose names) or Integer (layer number)
|
|

|
The minimum spacing required between the via cuts.
