How can I debug the S-Function generated for SIL simulation with a target from Embedded Coder 5.5 (R2011a)?

I use Embedded Coder to run SIL (Software-In-the-Loop) simulations. I would like to be able to debug the S-Function that is generated for the SIL simulation.

To debug the SIL S-Function you need to build the necessary libraries with debug information. Please follow the steps below to do this.

1.

Check the ”Verbose build” check box under Code Generation > Debug in the Configuration Parameters.

2.

Prepare and generate code for model with the required settings to generate the SIL-block. For details on the required settings, please see:

http://www.mathworks.com/help/releases/R2011a/toolbox/ecoder/ug/bsf5v22.html

3.

Edit the generated make file

\<model>_<target>_rtw\<model>.mk

by changing the DEBUG_BUILD flag in the following section to 1:

# To enable debugging:
# set DEBUG_BUILD = 1
DEBUG_BUILD             = 0

4.

Close the model with the SIL block and execute the command

>> clear mex

to make sure the SIL S-Function MEX file is not locked.

5.

Execute the file

\<model>_<target>_rtw\<model>.bat

To rebuild the model with debug information.

You can do this from within MATLAB by making the

\<model>_<target>_rtw\

folder your current directory and then execute:

>> !<model>.bat

6.

The project is now built for debugging.
