Concurrent Layout Toolbar in Manager Mode

To perform concurrent layout editing, you first need to initialize the design to make it ready for concurrent editing. Therefore, when you start the Concurrent Layout assistant for the first time for a design, only the Initialize button is available on the Concurrent Layout toolbar.

Click Initialize to make the design ready for the concurrent editing. This annotates the design so that it opens in the Concurrent Layout environment next time.

This step cannot be undone and will disable Connectivity - Generate All From Source. If needed, use this command before you initialize the cellview for Concurrent Layout editing.

After you initialize the design, remaining buttons on the Concurrent Layout toolbar are enabled in manager mode.

The following table lists the functions of the different buttons on the Concurrent Layout assistant toolbar:

Icon	Command	Description
	Initialize	Initializes the design for concurrent editing.
	Define Design Partition	Displays the Define Design Partition Form form that lets you create and configure design partitions.
	Merge/Un-Merge	Displays the Merge Form form that lets you merge or reject design partition views that have been submitted to be merged with the top design.
	Close Design Partitions	Cancels checkout of design partition views. This should be the last step of merge after the top design is checked-in. This option is available only in the design management environment.
