Exercise 12.3 - Stateflow to SysML

Objectives

The new learning objectives of this exercise are to generate a state machine structure in a MagicDraw SysML model from a state machine in Simulink Stateflow.

Preparation

This exercise assumes the student has

  • Cameo System Modeler 18.0 - 19.0 (or MagicDraw with SysML plug-in) installed correctly on his or her machine with a valid license for use, and

  • Syndeia 3.3 installed as a plugin for Cameo/MagicDraw with a valid license for use

  • Syndeia Stateflow interface, correctly installed with a valid license for user.

  • MATLAB/Simulink/Stateflow installed, licensed and available to the user,

  • A local operating system network connection in the Syndeia Repository Manager

The user can use any local operating system network connection they have available. It is generally advisable to carry out these exercises in a non-production repository, a "sandbox", set up for training and practice purposes.

  • Completed Exercise 12.2 and either still has the SysML model open or has saved and reopened it.

Exercise

  1. We start from the model at the end of Exercise 12.2. Save and close the Stateflow model.

  2. Create an empty package in the Syndeia Tutorial Testbed.mdzip (get it here - SysML Models, Profiles and Mappings) SysML model (Three State Model Part 2 in this example).

  3. In Syndeia, go to the Connection Manager tab. Navigate through the SysML model in the left column to show the Three State Model Part 2 package and your local operating system network connection on the right side to show the StateFlow model 1_Demo_ Stateflow, as in in Figure 2.

     

  4. Select Model Transform for Connection Type in the central column. Drag and drop the ThreeStates statechart onto the destination folder in the local operating system. Click Yes to confirm.
    CAUTION: Drag the Statechart, as highlighted in Figure 2, not the state machine, to create a state machine in the SysML model.

  5. When complete, expand the SysML model in the left column to view new SysML ThreeStates state machine, as shown in Figure 3.

  6. In MagicDraw, create a SysML state machine diagram in the new state machine. It should appear similar to Figure 4.
