Rapid Prototyping Program Framework

Generating code for a Simulink model results in at least four files — model.c,

model.h, model.prm,andmodel.reg,wheremodel is the name of the Simulink

model. This code implements the model’s system equations, contains block

parameters, and performs initialization.

The Real-Time Workshop’s program framework provides the additional source

code necessary to build the model code into a complete, stand-alone program.

The program framework consists of application modules (files containing

source code to implement required functions) designed for a number of

different programming environments.

The automatic program builder ensures the program is created with the proper

modules once you have configured your template makefile.

The application modules and the code generated for a Simulink model are

implemented using a common API (application program interface). This API

defines a data structure (called a

SimStruct) that encapsulates all data for

your model. Note that the embedded-C target does not have a

SimStruct,but

does have a common calling syntax for model execution.

This API is similar to that of S-functions, with one major exception: the API

assumes that there is only one instance of the model, whereas S-functions can

have multiple instances. The function prototypes also differ from S-functions.

Rapid Prototyping Program Architecture

The structure of a real-time program consists of three components.Each

component has a dependency on a different part of the environment in which

the program executes. The following diagram illustrates this structure.
