Description
Selectively removes a layer pair constraint value for the given layers or layer purpose pairs from a specific constraint group or from all constraint groups.
Arguments
|
-all
|
Removes the constraint from all constraint groups.
|
|
-allMembers [true|false]
|
|
|
When set true, removes all members of the constraint from the given group (-group) or from all groups (-all). This is particularly useful for removing all members from an AND or OR group.
Default: (false) Removes only the first member of the constraint.
|
|
-constraint s_constraintName
|
|
|
Specifies the name of the constraint to remove.
|
|
-group s_groupName
|
Specifies the group from which to remove the constraint.
|
|
-hardness {hard | soft | preferred | default}
|
|
|
Removes the constraint value for the given enforcement setting. If this was the last set value for the constraint, the constraint is removed from the constraint group(s).
|
|
|
default
|
Removes the first value found: hard or soft.
|
|
|
hard
|
Removes the hard value.
|
|
|
preferred
|
Removes the first value found: soft or hard.
|
|
|
soft
|
Removes the soft value.
|
|
-layer1 s_layerName
|
Specifies the name of the first layer associated with the constraint to remove.
|
|
-layer2 s_layerName
|
Specifies the name of the second layer associated with the constraint.
|
|
-model {OXIDE1 | OXIDE2 | OXIDE3 | OXIDE4}
|
|
|
Removes the constraint value for the given antenna model. If this was the last set value for the constraint, the constraint is removed from the constraint group(s).
|
|
-purpose1 s_purposeName
|
|
|
With -layer1, specifies the first layer purpose pair for the constraint.
|
|
-purpose2 s_purposeName
|
|
|
With -layer2, specifies the second layer purpose pair for the constraint.
|
|
-symmetric
|
Indicates that layer1 and layer2 are considered interchangeable. By default, layer pair constraints are not symmetric.
|
|
-verbose [true|false]
|
When set to true, the constraint name(s) and group(s) are output.
