Difference between Simulink Coder and Embedded Coder

Would you please let me know what is difference between two toolboxs "Simulink Coder" and "Embedded Coder"? And is there any possibility to generate c++ code from Embedded coder?

Answer 1

[Sebastian Castro]

Both Simulink Coder generate C code from Simulink models, and both of them can put that C code in a C++ wrapper to be effectively integrated with other C++ code.

The main difference between these products is:

• Simulink Coder generates code with the purpose of the model being able to run standalone without a MATLAB license, or to verify the behavior of the generated code on a host computer.

• Embedded Coder generates readable code that can be much more finely configured, customized, and optimized through various settings and constructs. Embedded Coder also provides support for automatically building the generated code on embedded systems (hence its name).

Thanks a lot for your answer!

Would you please let me know how I could use command line to generate C++ code for a *.slx file? I am not aware of any command regrading Embedded coder Toolbox.

[Sebastian Castro]

The MATLAB functions to generate code are slbuild and rtwbuild :

But as I know these are in Simulink Coder Toolbox rather than Embedded Coder Toolbox. codegen is a command in Embedded Coder Toolbox for generating C++ codes from *.m file rather than *.slx files, right?

[Sebastian Castro]

codegen is a MATLAB Coder function, so it works on MATLAB files (.m extension)

rtwbuild and slbuild are indeed Simulink Coder functions, but will also work with Embedded Coder. The only difference is whether your model is set up with the grt.tlc (Simulink Coder) or ert.tlc (Embedded Coder) system target file in its configuration parameters.

Thanks a lot! Really appreciate it! Now I have all my answers!

thax for such gret answers ...!!

As others have mentioned:

• MATLAB Coder enables users to generate C/C++ code from MATLAB algorithms
• Simulink Coder does the same for Simulink models
• Finally, Embedded Coder is an add-on to either MATLAB Coder or Simulink and unlocks additional code optimization, verification, and targeting capabilities (such as PIL)

For those interested, you can find a list of additional capabilities that Embedded Coder adds to MATLAB Coder here:
