When switched on, instances and pins with status unknown that are wholly inside the PR boundary after the edit are updated to status placed. Instances and pins with status placed that are wholly outside the PR boundary after the edit are updated to unknown.

To update the placement status of instances or pins in designs that are loaded in Layout XL for the first time, or which have been edited outside the Layout XL or GXL environment, do one of the following.

• Choose the Place – Update Placement Status menu command.
• Use the lxUpdatePlacementStatus SKILL function.
