Knowledge Booster Training Bytes - Enhance Layout Productivity with Virtuoso CLE

Are you using the sequential Virtuoso Layout flow?

Have you ever wished to perform multiple layout designing and editing tasks in parallel so that more work can be done in given time?

If your answer is yes, Virtuoso Concurrent Layout (CLE with E for editing) might be the solution for you. Use it to create multiple partitions in the design and have designers work in parallel, which helps save time and enhances your layout productivity!

In this Knowledge Booster blog, let’s talk about and explore how to do layout design tasks using concurrent editing. The blog:

• Introduces the training materials and videos that can help you understand and use this feature
• Shows how to earn a digital badge by passing an exam for the course

What Is Concurrent Layout Editing?

Virtuoso Concurrent Layout Editor is a layout editing environment that enables designers to work concurrently on the same cellview within the Virtuoso environment. As the designers work in parallel, using concurrent layout helps in bringing down the designing time and, as a result, increases productivity. You can perform concurrent editing in Virtuoso Layout Suite XL combined with 4 GXL flexible license tokens and Virtuoso Layout Suite EXL.

Concurrent Layout Flow

1. Initialize the Top Design for Concurrent Layout Editing: The first task for the manager is to initialize the design to get it ready for concurrent editing.

2. Define the Design Partitions: After the design is initialized, you can start defining the area-based/layer-based design partitions based on your editing requirements.

3. Edit the Design Partitions: After the required design partitions and design partition views are created, designers can start editing the allocated design partition views.

4. Import the Peer Design Partitions: You can import the changes made in the peer design partitions and view the updated design.

5. Merge the Top Design: After the designers have completed editing the design and submitted their respective design partitions for merge, the manager needs to review these requests and then either approve or reject the merge requests.

The manager needs to commit the changes in CLE to complete the merge process and save the merged changes into the top design. After all the design partitions are merged with the top design, the manager can delete and clear all the design partitions and exit the Concurrent Layout Editing environment.
