minParallelWithinViaSpacing

Specifies the spacing required between a cut and a neighbor cut when the edge of the neighbor cut is within a given distance.

Either minParallelWithinViaSpacing or minParallelViaSpacing can be specified for a cut layer, but not both.

minParallelWithinViaSpacing Quick Reference

Value Type

minParallelWithinViaSpacing constraints have a Value that represents the required spacing between a cut and a neighbor cut when the conditions are met.

Parameters

• oaCutDistance (Value) specifies that the constraint applies only when there is a neighbor cut edge that is less than this distance from the edge of a cut.
• exceptConnectivityType (StringAsIntValue, optional) specifies that the constraint applies to all vias except same net vias. The only valid value for this parameter is sameNetConnectivity. By default, the constraint applies to all vias.

Examples

set_layer_constraint -constraint oaMinViaSpacing \
  -layer V2 -hardness hard -Value 0.09 
set_constraint_parameter -name oaCutDistance -Value 0.02
set_layer_constraint -constraint minParallelWithinViaSpacing \
  -layer V2 -hardness hard -Value 0.1
