SysML Features

SysML model transformation to Simulink and Modelica

19.0 sp3 version allows users to export standard SysML models into Simulink (incl. Stateflow, Simscape) and Modelica models based on a standard mapping provided by new OMG SysPhS specification (SysML Extension for Physical Interaction and Signal Flow Simulation).

This one-way transformation supports both black-box or full implementation which includes parametrics, statemachines, internal structures with ports, interfaces and connectors.

Examples of Simulink export

Simulink Import

The SysML plugin has undergone some major improvements. Simulink model files can now be imported and represented as SysML Blackbox Blocks. Once the file is imported, you can select input and output ports to be represented as Flow ports on the Block. Additionally, the imported Simulink model can be simulated using the Cameo Simulation Toolkit.

Contextual Relationships

  • Enhance your modeling experience – contextualize Allocate, Refine, Satisfy, Trace, and Verify relationships to consider the context the connected properties are used in. Beginning with this release, users can more easily create and keep contextual relationships up to date in diagrams and matrices. 

Creating contextual relationships to define the context they are used in
  • You can now drag and drop the property directly on the Requirement shape in the symbol diagram to create the contextual Satisfy relationship automatically.

Flow Management Improvements

In the SysML Internal Block Diagram, the automatic delegation functionality:

  • creates a connector from the port to the nearest border. 

  • creates connectors with relevant ports between the ports of the nested parts (delegate).

  • realizes the existing flows on the newly created connectors.

Instance Improvements

  • Now you can save instance values to Blocks as default values. Learn more >>

  • The naming of the nested parts created by Create Instance wizard or in the Instance Table is improved.

  • The new Clone with parts action in the Instance Table toolbar and selected row's shortcut menu copies not only the selected Instance but its nested parts as well.

Modeling and Infrastructure

Model-Based Product Line Engineering

Product Line Engineering has been significantly extended by implementing the Model-Based Product Line Engineering (MBPLE) capability. In addition to integration with PLE tools (Big Lever Software Gears and Pure Variants), it is now possible to perform PLE in modeling tools without using third-party tools.

ISO 26262 Functional Safety Plugin

We are proud to introduce the brand new ISO 26262 Functional Safety Plugin. This plugin tightly integrates functional safety with MBSE (requires SysML plugin or Cameo Systems Modeler) and supports the ISO 26262 standard (the adaptation of IEC 61508) designed to comply with needs specific to the application sector of Electric & Electronic (E/E) systems within road vehicles. The ISO 26262 Functional Safety Plugin provides end-users with the means to perform hazard analysis and risk assessment:

  • Define Malfunctioning Behaviors for each Function

  • Specify an Operational Condition Library

  • Define Operational Situations as a combination of Conditions

  • Combine Malfunctioning Behaviors with Operational Situations to define Accident Scenarios

  • Specify a Hazard Library

  • Define System Level and Vehicle Level Effects

  • Combine Hazards, Effects, and Accident Scenarios into Hazardous Events

The plugin also provides a way to define functional safety concepts (safety requirements and perform ASIL decomposition) as well as generate safety reports. 


A HARA Table allows you to define Hazardous Events as a combination of Hazards, Effects, and an Accident Scenario. The description area shows all the information about the selected Hazardous Event.

Custom Hierarchy in Tables

Modelers now have more freedom to decide how to organize elements in tables. Simply choose one of the tree-view options to display elements hierarchically and see the changes in the table structure reflect the criterion you have specified:

• Containment: displays the decomposition of elements related by Containment.
• Structure: displays the decomposition of Part properties related by Composition.
• Custom: displays the decomposition of elements related by any specified criteria.

Stay up to date with the changes in your model by enabling the Suspect Links tracking. You can now track the changes applied to requirements linked to other model elements, as well as keep track of the changes that affect the selected model elements at the chosen end (source or target) of the specified dependencies.

Further Improvements

  • Now you can create nested structures quickly by pasting structural lists on Composite Structure and Internal Block diagrams.
  • To quickly create Activity Actions you can simply paste a copied list from any source of information. The Actions will be created and connected.
  • ReqIF import/export has been improved as well. From now on, all existing images are attached to the model upon ReqIF import and added to the ReqIF file upon export. 
  • ID prefixes no longer come with the applied HTML styles. Instead, all IDs are imported/exported as plain text. 

  • It is now possible to specify the element properties to be shown on the shape by default in a few clicks.

  • You can now wrap long text into multiple lines to display all of it in a table cell.

  • The modeling tool now allows entering an unlimited number of entries into the table cell to enable displaying multiple values/plain text lines in a table cell.

  • To save time, you can now create multiple relationships in matrices simultaneously.
  • The redesigned Documentation property group in the Specification window allows you to have all comments annotating model elements in one place as well as create and manage them easily when needed.

Lock-Free Model Editing

Locking elements prior to modifying them is now a thing of the past with the introduction of the Lock-free model editing mode (a.k.a an optimistic locking). You can continue using locks if that is what suits your team’s needs best; however, the Lock-Free editing mode is a simple yet effective way to boost modeling productivity.

To start using the Lock-free editing mode, first enable it in the project, after which you can work on model elements freely, without locking them. Consequently, there is no need to wait until locks are released by other users to work on the same or related parts of the model. If conflicting changes occur, you can handle them in the Conflicting Changes panel to prevent data loss.

Disconnected Team Collaboration Usability

The Disconnected team collaboration UI has been rebuilt from the ground up. The improved feature usability allows distributed teams working on the same server project to update it with the changes from the locally exported .mdzip file more conveniently and with a significantly reduced amount of manual steps.

Not only can you now update projects without having the target ones open in the modeling tool, you can also manage used project changes more easily. Additionally, the newly-implemented smart branch selection algorithm ensures configuration-aware update of server projects and smoother project merging in the future.

Further Merge Usability Improvements

Along with improved Merge usability and bug fixes, the 19.0 SP3 release adds adjustments to common ancestor calculation algorithm rules. As a consequence, subsequent project merging iterations can be carried out more effectively without the need to repeat previously made merge decisions.

Other Enhancements

  • For your convenience, we have moved an environment option Support Mount Points of Usages in Teamwork Cloud from Save/Load to the Collaboration node. 
  • When working with change sets, you can now discard both suspended and all local changes in an active change set.

  • The Maintain Mount Points of Used Projects option can now be accessed even more conveniently. It has been added to the Update from Local Project and Add Project to the Server dialogs.
  • Indirectly used projects can now be hidden or unhidden automatically together with directly used projects when their status changes, such as upon the used project update, remove, or merge.
