Stateflow

Code Files

Code files for the Simulation target (sfun) are generated for each model and placed in the subdirectory sfprj/build/<model>/sfun/src of the current directory, where <model> represents the name of the model.

Note    Do not keep any of your custom source files in the sfprj subdirectory of your model directory.

The code generated for the simulation target sfun is organized into the following files:

• <model>_sfun.h is the machine header file. It contains the following:
• All the defined global variables needed for the generated code
• Type definition of the Stateflow machine-specific data structure that holds machine-parented local data
• External declarations of any Stateflow machine-specific global variables and functions
• Custom code strings specified via the Target Options dialog box
• <model>_sfun.c is the machine source file. It includes the machine header file and all the chart header files (described below) and contains the following:
• All the machine-parented event broadcast functions
• Simulink interface code
• <model>_sfun_registry.c is a machine registry file that contains Simulink interface code.
• <model>_sfun_cn.h is the chart header file for the chart chartn, where n = 1, 2, 3, and so on, depending on how many charts your model has (see the following note). This file contains type definitions of the chart-specific data structures that hold chart-parented local data and states.
• <model>_sfun_cn.c is the chart source file for chartn, where n = 1, 2, 3, and so on, depending on how many charts your model has (see the following note). This chart source file includes the machine header file and the corresponding chart header file. It contains the following:
• Chart-parented data initialization code
• Chart execution code (state entry, during, and exit actions, and so on)
• Chart-specific Simulink interface code

Note    Every chart is assigned a unique number at creation time by Stateflow. This number is used as a suffix for the chart source and chart header file names for every chart (where n = 1, 2, 3, and so on, depending on how many charts your model has).
