target throughout development. The real-time format is the most
comprehensive code format and supports almost all the built-in blocks.
If, however, your application demands that you limit source code size, memory
usage, or maintain a simple call structure, then you should choose the
embedded-C format.
Finally, you should choose the S-function format if you are not concerned about
RAM and ROM usage and want to:
• Componentize a model for scalability
• Create a proprietary S-function
.dll or MEX-file object
• Interface the generated code using the S-function C API
• Speed up your simulation
More details for each code format appear in the following sections.
Choosing a Target
To choose a target, you must specify these files:
• System target file
• Template makefile
• Makefile
Every target has all three of these files and is represented in the System Target
File browser entry associated with it. See “The System Target File Browser” on
page 3-11 for more information on the browser.
Typically, the system target file will specify the code format. If the system
target file does not specify one, the default is real-time.
Table 12-1 shows the various options available for each code format/target
available in the Real-Time Workshop.
