destroy_unused_netoverride_groups
destroy_unused_netoverride_groups
Description
Removes any net override constraint groups that were created in the current session but are not currently referenced by any nets, routes, or other groups. This is useful when set_preferred_layers is issued in the session, which creates new constraint groups named *_netoverride_*, and then the preferred layers are unset (unset_preferred_layers). If the new net override constraint groups are no longer needed, run this command before saving the database to OpenAccess to prevent unnecessary bloating of the database.
