Generated S-Function

Represent model or subsystem as generated S-function code

Libraries:
Simulink Coder / S-Function Target

Description

An instance of the Generated S-Function block represents code that the code generator produces from its S-function system target file for a model or subsystem.

Requirements

The S-Function block must perform identically to the model or subsystem from which it was generated.
Before creating the block, explicitly specify Inport block signal attributes, such as signal widths or sample times. The sole exception to this rule concerns sample times, as described in Sample Time Propagation in Generated S-Functions.
Set the solver parameters of the Generated S-Function block to be the same as the parameters of the original model or subsystem. The generated S-function code operates identically to the original subsystem. For an exception to this rule, see Solver Type for Top Models with Generated S-Functions.

Examples

Function Reuse in Generated Code

Configure an atomic subsystem for generating reusable code. To specify that the code generated for a subsystem execute as an atomic unit, on the Block Parameters dialog box, select the Treat as atomic unit parameter. That parameter enables the Function Packaging parameter on the Code Generation tab. The Function Packaging parameter has these four settings:
