SysML Plugin

Released on: November 21, 2019


The 19.0 SP3 release is packed with a number of new capabilities and improvements. Now you can export SysML models and diagrams to Simulink, Stateflow, S-functions, Simscape, and Modelica. Simulink and FMU models can be imported or updated using a new import dialog with optional ports and property selection. Other noteworthy features include contextualized relationships in diagrams and matrices, flows, ports and instances management enhancements, structural text copy/paste as nested structures in IBD and more.

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.

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.

  • You can now drag and drop Requirements from the Model browser to the Internal Block diagram and then satisfy them in the IBD context.

  • For your convenience, Requirements are now also shown within the elements that satisfy them in the Structure tree. 


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.

  • Pins for the Opaque Actions can now be created automatically. Learn more >>
