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 has been moved to Project Options, animation delay affects only visible diagrams to provide better user experience, guard evaluation on transitions expressed innatural 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.
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.

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.

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.
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.
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.
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.
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.
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.
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).
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 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.
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.

Performance Improvements
Project Merge Improvements
Project Merge has undergone considerable performance improvements. Modeling tool version 20.0 requires 3-4 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 speed has increased by 20-70% in 20.0 compared to 19.0 SP4.
Charts comparing merge performance in speed and memory modes.
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.
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 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.

Recent modeling tool performance improvements have led to an increase in the copying/pasting operation speed. Now you can copy and paste data noticeably faster for maximized productivity.
A chart comparing the copy&paste operation time in various scenarios.
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.
Web portal reports are no longer available. For more effective model publishing and reviewing on the web, use Cameo Collaborator.
WSDL Code Engineering and WSDL diagram are no longer available.
C# Code Engineering and C# Professional Edition are no longer available.
The 32-bit installation files are no longer offered for download.
From Teamwork Server to Teamwork Cloud
Teamwork Server is no longer supported in the latest release. Teamwork Cloud should be used as a product for collaborative modeling and model version control. Customers still using Teamwork Server have to migrate their server projects to TWC 19.0 series first and then upgrade to TWC 20.0.
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.
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.
