Terms Used in Concurrent Layout Editing

Listed below are some important Concurrent Layout terms you need to know before you start using the software:

Area-based design partition

Defines one or more areas for a designer to edit within.

Design manager

Defines the design partition for each designer and merges the respective design partition views back to the top design.

Design partition

A design partition divides the design responsibilities among designers. You can create as many partitions as needed in a design and new design partitions can be created at any time.

Design partition view

The on-disk layout cellview that stores incremental edits to the top design separately. These updates can be reapplied to the same top design later.

Designer

A user who edits in the assigned design partition.

Free design partition

Allows the user to work on any object, net, and any part of the design.

Net-based design partition

Defines a net set for a designer to edit only those objects that have allowed or no connectivity.

Object-based design partition

Defines the object ownership for a designer to edit. The person who created the object also owns it.

Peer designer

A designer working on another design partition of the same top design concurrently. Updates made by the peer designer are saved to a different design partition view.

Top cellview (or top design)

This is the initial layout cellview to be concurrently edited after initialization. After opening in memory it is called the top design.
