Your external code can include include this file, whose general name is model. In the function definition, the algorithm reads input data and writes output data by directly accessing the global structure variables. Due to the void void interface and the direct data access, the function is not reentrant. If you call the function multiple times in an application, each call reads and writes input and output data to the same global structure variables, resulting in data corruption and unintentional interaction between the calls.
The function also initializes the error status. The function directly accesses the global variables, which means the function is not reentrant. Generate Reusable Code. You can configure the generated code as reentrant, which means that you can call the entry-point functions multiple times in an application. With this configuration, instead of directly accessing global variables, the entry-point functions exchange input, output, and other model data through formal parameters pointer arguments.
With these pointer arguments, each call can read inputs and write outputs to a set of separate global variables, preventing unintentional interaction between the calls. To call the generated code multiple times in an application, your code must allocate memory for a real-time model data structure per call.
The function also allocates memory for the substructures that the fields in the model data structure point to, such as the input and output structures.

Simulink Coder uses the GRT code format, which is intended for rapid prototyping.
Embedded Coder uses the ERT code format, which is intended for production deployment. To generate code and build a program executable, initiate the build process. Force Top Model Build.

You can control the default representation of test points by specifying code generation settings for the Internal data category of data in the Code Mapping Editor see Configure Default Code Generation for Data. You can specify that the build process ignore test points in the model, allowing optimal buffer allocation, by using the Ignore test point signals parameter.
Ignoring test points facilitates transitioning from prototyping to deployment and avoids accidental degradation of generated code due to workflow artifacts.
See Ignore test point signals. Virtual buses do not appear in generated code, even when associated with a test point. To display a bus in generated code, use a nonvirtual bus or a virtual bus converted to a nonvirtual bus by a Signal Conversion block.
Workspace variables are variables that you use to specify block parameter values in a model. Parameter objects that you store in a workspace, such as the base workspace, or in a data dictionary. When you set Default parameter behavior to Tunable , by default, workspace variables appear in the generated code as tunable fields of the global parameters structure. If you use such a variable to specify multiple block parameter values, the variable appears as a single field of the global parameters structure.
The code does not create multiple fields to represent the block parameters. Therefore, tuning the field value during code execution changes the mathematical behavior of the model in the same way as tuning the value of the MATLAB variable or parameter object during simulation. If you have Embedded Coder, you can control the default representation of workspace variables by specifying code generation settings for categories of parameter data in the Code Mapping Editor see Configure Default Code Generation for Data.
The Model parameters category applies to variables that you store in a model workspace. The External parameters category applies to variables that you store in the base workspace or a data dictionary. By default, the code generator assumes that other systems and components in your application do not need to access internal data. For example, internal data are subject to optimizations that can eliminate them from the generated code. For prototyping and testing purposes, you can access internal data by clearing the optimizations or by configuring test points and applying storage classes see Preserve Variables in Generated Code.
For optimized production code, configure individual data items to appear in the generated code as part of the model interface. Depending on the reentrancy of the generated code, that is, the setting that you choose for Code interface packaging , you can configure each data item in a model to participate in the interface by appearing in the code as one of these entities:. The table shows the mechanisms that each category of data can use to participate in the interface.
Alternatively, connect the signal to a root-level Outport block. For a single-instance algorithm you set Code interface packaging to Nonreusable function , apply storage classes directly to individual data items by using the Model Data Editor or the Property Inspector.
With a directly applied storage class, a data item appears in the code as a global symbol such as a global variable. The storage class also prevents optimizations from eliminating storage for the data item. You can apply storage classes to signals, block states, and block parameters. For block parameters, you apply storage classes indirectly through parameter objects such as Simulink.
However, for a signal, consider connecting the signal to an Outport block at the root level of the model. Then, optionally, you can apply a storage class to the block. In the block diagram, the Outport block shows that the signal represents a system output. For a reentrant algorithm you set Code interface packaging to Reusable function , use different techniques to configure data items to appear in the code as formal parameters arguments of the generated entry-point functions.
Alternatively, configure the signal as a test point see Appearance of Test Points in the Generated Code. If you do not want the signal to appear in production code, use a test point so that you can later select the model configuration parameter Ignore test point signals.
Alternatively, connect the signal to an Outport block at the root level of the model. Connecting the signal to a root-level Outport block prevents optimizations from eliminating the signal from the code.
To help with signal routing in a large model, use Goto and From blocks. For a block parameter, create a parameter object such as Simulink. Parameter and directly apply a storage class other than Auto to the object.
