1. Create the IBM Engineering Systems Design Rhapsody® project

   
   
   • Create a new SysML project and add the Mathworks® Simulink® profile for C++ or SimulinkC profile for C.
   • Create a new Block and set its stereotype to SimulinkBlock
   • Right-click the block and open Display options. In the Ports tab, select All (for Ports to Display)
      

2. Create the Mathworks® Simulink® model

   
   
   • Open Mathworks® MATLAB® and set the directory to a suitable location
   • Right-click the Mathworks® MATLAB® browser, select "New File > Model". Name the model "ImportTest"
   • Open the Simulink® model and select the Simulink® Library browser
   • Drag the following elements to the model: a)In1 b)Gain and c)Out1
   • Arrange the elements and connect them together in the order they were added. Set the gain to 3.
     
     
      
   • Save the Simulink model

3. Configure the Simulink model code generation.

   • Note you can use the preset Configuration Set for Rhapsody.  If you do, skip section 3 below.
   • Open the "Model Configuration Parameters" in the toolbar.
   • Select the "Solver" section.
     
     
     • Set the Solver type to "Fixed-step"
   • Select the "Code Generation" section.
     
     
     • Set the System target file field to "ert.tlc"
     • Set the language to C or C++, depending on the IBM Engineering Systems Design Rhapsody® Simulink profile selected previously in PartA.
     • Set the Generate Code Only option to True
   • Select the "Symbols" section
     
     
     • Set Global Variables to 
        

         $R$N$M

       
       
     • Set Global Types to
        

         $N$M

       
       
     • Set Fieldname of Global Types to
        

         $N$M

       
       
     • Set Subsystem Methods to
        

         $N$M$F

       
       
     • Set Subsystem Method Arguments to
        

         rt$I$N$M

     • Set Local Temporary Variables to
        

         $N$M

       
       
     • Set Local Block Output Variables to
        

         rtb_$N$M

       
       
     • Set Constant Macros to
        

         $N$M

       
       
     • Set Shared Utilities to
        

         $N$C

       
       
     • Set System-Generated Identifiers to "Classic"
       
       
        
   • Select the "Interface" section
     
     
     • Set the Code Interface Packaging to "Nonreusable function"
   • Save the Simulink® model
   • Build the Simulink® model (since we specified only code generation, this will not actually build the code)
   • You should see a successful code generation report
     
     
      
   • Close the MATLAB® and Simulink® windows.

4. Import the Simulink® model into the IBM Engineering Systems Design Rhapsody® project

   
   
   • Go back to the IBM Engineering Systems Design Rhapsody® project created earlier
   • Right-click the SimulinkBlock and select "Import/Sync Simulink Model"
   • In the window select:
     
     
     • The MATLAB.exe in the win64 directory
     • The Simulink® model created in step2 (ImportTest.slx)
     • The source files (ImportTest.cpp from the ImportTest_ert_rtw directory)
       
       
        
   • Press Import/Sync. Press OK on the success message once it has completed.
   • Note that the In1 and Out1 ports from the Simulink model are now present on your SimulinkBlock
     
     
      
   • Run the Code menu > Regenerate on the project.
   • Run Code menu > Generate/Make/Run to build the project.

5. Running the Imported SimulinkBlock

   • Add a Block called BufferIn:
     
     
     • Open the display options for the block, select show all ports on the Port tab
       
       
        
     • Add a flowport to the block of name "In1", type RhpReal and direction "Output".
     • Add a Value Property to the block called "In1" of type RhpReal, initial value: 3
     • Add a statechart to the block
   • Add a Block called BufferOut:
     
     
     • Open the display options for the block, select show all ports on the Port tab
     • Add a flowport to the block of name "Out1", type RhpReal and direction "Input".
     • Add a Value Property to the block called "Out1" of type RhpReal, initial value: 0
     • Add a statechart to the block
   • Right-click each block and select "Make an Object"
   • Connect each flowport pair using Connectors.
     
     
      
   • Add a panel diagram
     
     
     • Add a dial control, bind it to BufferIn::In1
     • Add a digital display control, bind it to BufferIn::In1
     • Add a digital display control, bind it to BufferOut::Out1
     • Enable animation in the configuration and run Code menu > GMR again.
   • When you adjust the dial, the first display shows the original value and the second display shows the value with a gain of 3.
