Modeling and Infrastructure

Layers Based on Legends

Diagrams can get extremely crowded as

the

a model evolves.

Therefore

For example, when highlighting a chosen piece of information

, for example

, only one specific aspect of the system becomes a

great

challenge. For your convenience, you can now filter diagrams by the selected Legend items to make only the necessary diagram layers stand out.

Extended Excel and CSV Sync

Three improvements

to synchronize

expanded the data synchronization between Excel or CSV files and a model:

  • Unique elements. Elements to be synchronized can now be identified not only by their name, but also by element property or tag value.
  • Direct relationships. From now on, you can import direct relationships between the source and target elements as easily as other elements.
  • Relationship ends. When importing relationships between different elements, you can select a specific property or tag to identify the source and target end of the relationship.

HTML Widgets in IBD Diagrams

Cameo Simulation Toolkit introduces a new powerful mechanism to integrate any third-party interactive HTML components (widgets) into SysML diagrams for simulation. A set of predefined widgets is available in UI Widgets Library. You can drag and drop widgets to IBD diagrams and connect them to appropriate value properties to provide inputs or read outputs. If you have basic HTML and JavaScript skills, you can manually create new custom widgets and integrate them into simulation.

Please note that the free Web Server for Cameo Simulation Tookit plugin is required for this functionality.

Displaying and Changing Runtime Values in Diagrams

WIth Cameo Simulation Toolkit 20.0 monitoring and manipulating simulation information has never been easier. Now you can display runtime values of Parts in all diagrams based on a Composite Structure Diagram as shown in the figure below. But that is not all, you can also modify runtime values directly in a diagram the same way you do it in the Simulation window.


This sample model demonstrates how you can view and change runtime values of Parts directly in an Internal Block Definition Diagram.

Back to top


Displaying Active State in Diagrams

Now diagrams based on a Composite Structure Diagram display the active States of Parts when simulating a model. Active states are shown on the bottom of Part shapes the same way they are displayed in the Variables pane of the Simulation window. This new feature improves the readability of simulation information because you no longer need the Simulation window to see how active States change when executing your model.


In this Internal Block Definition Diagram, you can see that active States are displayed both in the Simulation window and on the shapes of initialized Parts.

Back to top


Displaying Active State Images

Make your model simulation look more illustrative and vivid by displaying active State images on Part shapes. You can do that by assigning an Image Switcher to the Simulation Configuration from which you execute your model or by applying an image to a State. When states change during simulation, state images change as well as displayed in the following figure.


Here you can see how active State images are displayed when simulating a model.

Displaying Flowing Information

Cameo Simulation Toolkit 20.0 allows you to see what information is flowing via paths that are animated during model execution. In Activity Diagrams, the flowing item is displayed as a bubble with a label showing the item name. In diagrams based on a Composite Structure Diagram, a moving triangle is shown on an animated path as illustrated below.


The temperature value flowing in an Activity Diagram.

In this Internal Block Definition Diagram, you can see the neutral signal flowing from the GearShift to the Transmission Control Unit (TCU).

Sending a Trigger in Diagrams

Now sending a trigger during model simulation is even more convenient because you can do it right from a diagram without using the Simulation window. You can send a trigger directly from a Part shape in all diagrams based on a Composite Structure Diagram. When it is possible to send a trigger, a special button is displayed on a Part shape after selecting it.


Simply click the highlighted button to send a trigger from a Part. If it is possible to send several triggers, the trigger list will be displayed for you to select from.


Reorganized Simulation Options

All Simulation options have been moved from Environment Options to Project Options for better user convenience, as it allows customizing simulation to fit a particular project. In addition, all simulation settings will be exchanged among users who collaborate on a server.

Furthermore, most of the Simulation Configuration options are duplicated in Project Options now, so you can specify default values for execution without using Simulation Configuration.


As you can see in this figure, all simulation options are now accessible in the Project Options dialog.

Animation Delay Logic

Animation delay affects only visible diagrams now.  All closed diagrams and models run at full speed with no delays.


Interactive Guard Evaluation for STM and Sequence Diagrams

The guard conditions on transitions expressed in natural language cannot be evaluated, so the question dialog will be shown for you to choose.  This behavior is consistent with decision nodes in Activity Diagrams.


When simulating this State Machine Diagram, a user is asked to choose whether a user name is valid or not.

Simulink Co-Simulation in Activity Diagrams

A Simulink *.slx file can be dropped into an Activity Diagram to create «SimulinkBlock» Activity and  Call Behavior Action for it. If the file is attached to your project or stored in the project directory, Cameo Simulation Toolkit will be able to execute it with given input values and provide outputs to the action output pins.


In this Activity Diagram, a «SimulinkBlock» action has been created from a Simulink *.slx file.

Other

  • A new parameter -leaveprojectopen has been introduced into the command-line interface. 
    It allows leaving a project open for the next simulation if multiple property files are used in the simulation command.
  • Boolean and Enumeration values are represented in Timeline plots now.



  • A new Record Time option is added into CSV export configuration to be able to turn off the timestamp column when it is not needed, e.g., when recording Trade Study or Monte Carlo iterations.

TWC Project Load Memory and Speed Improvements

Project load memory and speed improvements have been implemented for Teamwork Cloud. The modeling tool now requires only 2GB of heap to load a project (first and second time) when working with TWC projects compared to 8GB in 19.0 SP4. Additionally, as a result of the UML metamodel changes mostly, SysML projects are now opened 2-3 times faster.

N.B Received results cover the project load only, excluding validation, diagramming, and further modeling tool feature usage.

N.B A red border on a bar chart in the image below indicates a low memory occurrence during testing.


Charts comparing load memory and speed improvements between different modeling tool versions.
  • 3 projects (sizes ranging from 1M to 2M) in 19.0 SP4 and 3 projects in 20.0 (sizes ranging from 750k to 1M) were used to run the tests.
  • Migration time is excluded because already migrated projects were used.

TWC Disk Footprint Improvements

Major TWC disk footprint-related changes are presented in this release. TWC 20.0 requires twice as less disk space for the same amount of projects with no history compared to TWC 19.0 SP4. In addition to this achievement, the disk size growth is cut nearly 5 times in TWC 20.0 compared to TWC 19.0 SP4 for those projects users work actively on.


A chart comparing TWC disk footprint between different modeling tool version
  • A database of 50 projects with 2021x commits each was used to run the tests. 
  • Project sizes ranged between 400k and 2.2M elements (average project size being 700k elements).

Partial Data Loading in Tables

Experience enhanced table loading and scrolling performance! Thanks to the newly-introduced Load Partial mode, data is now loaded in only visible rows, meaning that there is no need to wait until data is calculated in the entire table. What is more, fast scrolling has improved – it is now considerably smoother.

Profiling Changes in the UML 2.5.1 Metamodel

Significant changes have been implemented to the UML metamodel for performance reasons. The InstanceSpecifications, Slots, and ValueSpecifications are no longer used to store profiling data. Instead, new model element types and properties are introduced while some have been removed (see the diagram below).


Profiling changes in the UML metamodel.

As shown in the figure above, Element references the TaggedValue that is used to specify the Boolean, Integer, Real, String, or Element values of the applied stereotype properties. This approach uses fewer model elements to store profiling data, which leads to a decrease in the total number of elements in SysML and UAF projects by 40-80%.

N.B Expressions based on the previously implemented profiling data storing metamodel no longer work, meaning that they have to be updated manually.

Detecting Changes in Diagrams During Merge

You can now specify in the Environment Options dialog whether to compare only the direct or all the changes in diagrams during the Project Merge and Project Comparison operations. By default, only the changes made by the user in loaded (open) diagrams are analyzed, leaving out unintentional diagram changes that occurred due to indirect changes in the model. This feature not only eases both merge and project comparison processes for the user since the number of diagrams with changes is considerably reduced but also optimizes modeling tool performance.

Further Merge Usability Improvements

The model merge has undergone further usability improvements. From now on, changes from the Target and Equivalent Changes are automatically hidden by default, meaning that only the Source changes are shown. As a result, fewer changes need to be reviewed by the user.

What is more, the model merge has been extended by adding a capability to select which ancestor calculation algorithm to use. You now have the freedom to choose a Branch Point as an ancestor for your merges. This is especially useful in those cases when merge results become too complex to understand and analyze due to previously rejected changes. By default, Lowest Common Parent ancestor calculation algorithm is used.

Selecting the ancestor for future merges in the Merge Project dialog.
