Magic Cyber Systems Engineer
Released on: February 12, 2021
Version 2021x adds the ability to use layers in diagrams, automatically create legends, present diagrams or predefined sequences of diagrams in full screen to stakeholders, create compositions and aggregations in matrices, and use predefined element type filters when searching for the necessary model elements. Additionally, the usage of Simulink import and Modelica export has been extended with few enhancements, the Excel/CSV file import functionality has been reviewed and refreshed, and numerous improvements to Excel/CSV synchronization functionality in tables have been added.
Few powerful simulation features will change the way you simulate your models by using diagrams as a simulation dashboard. For your convenience, streaming behavior simulation is now supported and simulation options have been moved to Project Options, animation-delay affects only visible diagrams to provide better user experience, guard evaluation on transitions expressed in natural language are now interactive, and more.
This release brings significant performance and scalability upgrades in key product areas: Merge, Teamwork Cloud project load, Teamwork Cloud project saving, table loading, Excel and CSV files import, and such common modeling tool operations as Copy/Paste, Find, Numbering, Element Selection, and Validation.
Last but not least, project merge has been extended to give users the option to show only the changes in directly modified diagrams, hide Target and Equivalent Changes by default, and choose a specific ancestor calculation algorithm depending on merge scenario and expected outcome.

Modeling and Infrastructure
Layers Based on Legends
Diagrams can get extremely crowded as a model evolves. For example, when highlighting a chosen piece of information, only one specific aspect of the system becomes a challenge. For your convenience, you can now filter diagrams by the selected Legend items to make only the necessary diagram layers stand out.

Intelligent Legend Creation
Seems like Legend creation is a tiresome activity? Not at all! From now on, you can create Legends easier than ever before – extract them automatically from the elements displayed on your diagram instead of relying on a manual creation. What is more, you can now automatically extract Legend items for the existing Legends. Once the Legend items are created, you can customize their adornments representation. They can now be displayed as rectangular shapes or extended lines to represent paths and shapes in greater detail.
Extracting the Port Types legend according to the elements displayed on the diagram as symbols.
Direct the attention of your audience to the diagrams being presented! You can now present diagrams in full screen without showing such user interface components as model browser, diagram palette, status bar, and toolbars. That is not all! You can also define the sequence of diagrams to present one after another.
Renewed Excel/CSV File Import
You can import data from an Excel/CSV file directly to the model without installing Excel and CSV Import Plugins (read more about discontinued products). From now on, the newly created Excel/CSV Import dialog brings an easy to use and clearly understandable graphical user interface. It allows you to import content with just a few clicks by selecting the Excel/CSV file and specifying element mapping options. Additionally, you can save your maps to reuse them, collect saved maps in groups, manage those groups, and use an entire group instead of a single map for data import.

Extended Excel and CSV Sync
Three improvements 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.
New mapping options in the Excel/CSV Sync Options dialog: Identification Property, Identify Relationship (end) Source by, Identify Relationship (end) Target by.
Composition and Aggregation Relationships in Dependency Matrix
You can now define relationships between the elements in your model more accurately! The latest release gives you the ability to create and display Composition and Aggregation relationships in a Dependency Matrix.
Creating and displaying Composition, Aggregation, and Association in a Dependency Matrix.
Applying Legend items to the same element is more convenient since they are now grouped by Legend.
A reference from the image shape to the attached image is now created when attached images are displayed as diagram shapes.
The Diagram Tabs Limit is set to 20 to prevent high memory utilization. You can change this environment option at any time.
The smart autocompletion command Ctrl + Space now works for the Change Event expression in a State Machine diagram.
In the Select Element and Quick Find dialogs, elements can now be filtered by their types to narrow down search results.
- The Jython 2.7.2 version is now supported.
- The MARTE Profile version 1.2 is now supported.
- The Reader Edition is now available for all the 2021x version modeling tools. Contact your sales executive to request the license.
Simulink and Modelica Integration Improvements
Proxy Ports in FMU and Simulink Import
FMU and Simulink import now support Proxy Port creation. Once you have imported the external FMU/Simulink model, you can select the Proxy Port to be created in your model and then specify an existing or create a new Interface Block to be used as its type.
Selecting the Proxy Port and an Interface Block upon the external model import.
Simulink Model Import to Activities
You can import the Simulink model by dragging and dropping the Simulink file (*.slx) directly onto the Activity diagram. The Activity (stereotyped by «SimulinkBlock») which is assigned as behavior for the Call Behavior Action and its Input and/or Output Pins are created in the model.
Simulink import to Activity diagram.
Simulink Composite Signals export
You can now select how to export Proxy Port or Interface Block with multiple Flow Properties (composite signals): as bus Creators/Selectors or as bus In/Out ports.
IBD-based Selective Modelica Export
You can now use the Internal Block Diagram to select what to export to Modelica. Only parts, ports, and connectors appearing in this diagram are exported, rather than the entire model. See whole vs partial export comparison in the image below.
The difference between whole (exporting Block) and partial (exporting IBD) export to the Modelica file.
SysML 1.6 Support
As of version 2021x the SysML Plugin supports the SysML 1.6 specification which brings the following improvements:
- One more way to model conjugated ports is to create the Conjugated Interface Block which has the same features as its original Interface Block except that its Directed Features and Flow Properties are reversed (conjugated). Learn more about Conjugated Interface Block >>
- The ability to change the Binding Connector notation keyword from "equal" to sign "=". Learn how to create Binding Connector >>
- The new stereotype «AddFlowPropertyValueOnNestedPortAction» is created which enables values added to a flow property to propagate out through a specified behavioral port of an object executing the action, rather than all behavior ports exposing the flow property. It also enables values added to a flow property to propagate into objects.
- The AdjunctProperty principal type is changed from Element to NamedElement.
- The «PropertySpecificType» stereotype is renamed to «pst».
- The Value Type compartment attributes is renamed to properties.
- The initialValue compartment is renamed to initial values.
- The signal receptions compartment is renamed to receptions.
- The FlowDirection, FeatureDirection and ControlValue enumerations are renamed to FlowDirectionKind, FeatureDirectionKind and ControlValueKind respectively.
HTML Widgets in IBD Diagrams
Please note that the free Web Server for Cameo Simulation Tookit plugin is required for this functionality.

Streaming Activity Simulation
Cameo Simulation Toolkit 2021x supports the simulation of streaming activities when a system receives inputs and produces outputs even while behaviors continue to execute. As you can see in the example below, during simulation several actions can be executed simultaneously, and waiting tokens are displayed on action pins. Note that you can control the held token display in the Project Options dialog or Simulation Configuration properties.
An example of a streaming Activity.
This diagram shows the differences between streaming and non-streaming behavior execution.
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.
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.
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.
- 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.
Client-side Performance Improvements
Partial Data Loading in Tables
Experience enhanced table loading and scrolling performance! Thanks to the newly-introduced Load Partially mode, data is now loaded in only visible rows. There is no longer a need to wait until data is calculated in the entire table. Additionally, fast scrolling has improved; it is now considerably smoother.

Increased Excel and CSV files Import Speed
The import performance of data from an Excel or CSV file into the modeling tool adds a great experience while managing a large scope of data. The data import time using the table sync feature is significantly faster compared with the previous version (19.0 SP4). Also, the data import using the new Excel/CSV Import dialog is even better in comparison to Excel/CSV Sync feature. The import of 61k elements takes only 2 minutes (see the chart below).

- Numbering. Creating the first numbered element, copying/pasting numbered elements, renumbering elements recursively, and updating the last element ID is now 30-840 times faster.
A chart comparing the Numbering operations speed in 19.0 SP4 and 2021x projects containing 10M elements (including used projects).
Element Selection. Now you can search and select the needed elements (e.g., in the Select Element and Quick Find dialogs as well as drop-down lists) approximately 40-50 times faster.

Profiling Changes in the UML 2.5.1 Metamodel
Significant changes have been implemented in the UML metamodel for improved performance. 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%.
Note. Expressions based on the previously implemented profiling data storing metamodel no longer work, meaning that they have to be updated manually.
TWC-related Performance Improvements
Project Merge has undergone considerable performance improvements. The modeling tool version 2021x requires approximately 4-5 times less memory to successfully merge two server project branches, compared to 19.0 SP4.
A chart comparing merge memory consumption in different modeling tool versions.
Furthermore, the merge operation speed has increased by 20-70% in 2021x compared to 19.0 SP4. Both frequent (between close project versions) and infrequent (between distant project versions) merges can now be performed much faster!

TWC Project Load
Project load memory and speed improvements have been implemented for Teamwork Cloud. The modeling tool now requires only 2GB of heap to load a 2M SysML 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, SysML projects are now opened 2-3 times faster.
Note. Received results cover the project load only, excluding validation, diagramming, and further modeling tool feature usage.
Charts comparing project load memory and speed improvements between different modeling tool versions.
- Three projects (sizes ranging from 1M to 2M) in 19.0 SP4 and the same projects in 2021x (sizes ranging from 750k to 1M) were used to run the tests.
- Migration time is excluded because projects that had already been migrated were used for testing.
TWC Save to Local
In 2021x, great attention is paid to the memory consumption improvements. Saving a Teamwork Cloud project locally now requires less memory. For example, a 2M SysML project now consumes only 4GB of RAM, compared to 20GB in 19.0 SP4.

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.
An Environment option to specify the changes to detect in diagrams.
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.
