New & Noteworthy for Rational Rhapsody Design Manager 6.0.4

Client extension Improvements for managing remote requirements

New options are available for managing collections of remote requirements when you connect to a project area using the Rational Rhapsody Design Manager client extension. You'll see performance improvements when you use the options to add a collection from the Requirements Management application (RM) and filter the requirements contained in that collection.

These are the filters:
-All: Loads all requirements (default).
-Linked: Loads only those requirements that are linked to an element in a model.
-None: Doesn't load any requirements, but adds the collection.You can specify which filter you want to use when you add the collection:
-In the Rational Rhapsody browser, expand the Remote Resources package.
-Right-click the collection you want to work with, and then select Populate With.
-Select  All, Linked Requirements, or None from the list.
Tip: You can still load all linked requirements that are not contained in a collection, as in earlier versions of the product.  If an existing requirement is linked to a model, but is not part of a collection, the requirement is added to the remote resources package in your project.

Performance improvements for actively managed models

Performance has improved when you use the Rational Rhapsody Design Manager client extension to work with large actively managed models. You can see the performance improvements in these and other tasks:

-Load time for large models
-Opening large diagrams (400 elements or more)
-Reloading an entire project

These tasks are now at least twice as fast as in previous versions. You can see the comparison with the previous version in the table.

Table that shows the performance improvements:

  Performance improvements for saving change sets in actively managed mode

When you save change sets in actively managed mode, you should notice performance improvements. For example, if you use the AMR_System sample model and the project settings from the following image, saving updates to 28 diagrams in a change set that contains 220 resources takes approximately 40 seconds. In previous releases, saving the same changes took approximately 5 minutes.

Simulink Simulink diagram improvements

The display of large Simulink diagrams with many elements is now sharper and clearer in the Rational Rhapsody Design Manager web client.

For more information, see Story 58131.
Mathworks Simulink version 2016b is supported

You can now use Rational Rhapsody Design Manager with Mathworks Simulink 2016b.
Simulink model structure improvements

Rational Rhapsody Design Manager can now generate unique IDs for Simulink model elements, such as blocks, classes, or flowports.

As of this milestone, you can use the new capability for actions such as these:

-Import Simulink models that contain high-level hierarchical elements
-Preserve any OSLC links if you decide to rename a Simulink element

For more information, see Story 59004.
Model update improvements

The Rational Rhapsody Design Manager import engine can now update a Simulink model more efficiently at run time. You'll notice several performance improvements when you run the import engine.

No changes to a model: If no changes are detected, you get a message that the model is up-to-date, and the job completes. Previously, updates were slower because the job had to import the entire model again, even if no changes were detected.

No disruption of work: You can continue to work in a Simulink model while it is being imported, without your work being disrupted. Until now, diagrams in a model would open and close intermittently during the import.

Import status: You can check the status of a Simulink import job on the Activities page in Design Manager. Open the project area containing the model, and then click File > Activities.

Progress bar: A new message window has been added to the Simulink Matlab work area. The window shows the progress of a job as it completes.

Diagnostics: Details of each Simulink import job are now recorded in the Diagnostics log, including the status of each operation, and how long it took (in milliseconds) to complete. Previously, no diagnostics were captured for Simulink. Now, you can view the results and if necessary, save them in a local directory, or email them for support.

To run the diagnostics:
1. On the Design Management Application Administration page, click Run All Diagnostics.
2. Click Export Results to save the compressed file that contains the results to a local directory.
