Real-Time Workshop

Building for the Rapid Simulation Target

To generate and build an rsim executable, press the Browse button on the Real-Time Workshop pane of the Simulation Parameters dialog box, and select the rapid simulation target from the System Target File Browser. This picture shows the dialog box settings for the rapid simulation target.

Figure 11-1: Specifying Target and Make Files for rsim

After specifying system target and make files as noted above, select any desired Workspace I/O settings, and press Build. Real-Time Workshop will automatically generate C code and build the executable for your host machine using your host machine C compiler. See Choosing and Configuring Your Compiler and Template Makefiles and Make Options for additional information on compilers that are compatible with Simulink and Real-Time Workshop. The picture below shows rsim-specific code generation options that allow you to avoid using the Simulink solver module (i.e., use only the fixed step solvers packaged with Real-Time Workshop) and enable the rsim executable to communicate with Simulink via external mode.

Note    Rapid Simulation executables created without using the Simulink solver module can be transferred and run on computers that do not have MATLAB installed. When running an rsim executable on such a machine, it is necessary to have the following dlls in your working directory: libmx.dll, libut.dll, and libmat.dll. These dlls are required for the rsim executable to write and read data from a .mat file. This deployment option is not available for rsim executables that rely upon the Simulink solver module.
