Simulink Compiler Workflow Overview

Simulink® Compiler™ lets you share simulations as standalone applications. Simulink Compiler extends the capabilities of MATLAB® Compiler to allow Simulink sim command and associated Simulink functions in the deployed script or application. For more information about MATLAB Compiler, see MATLAB Compiler documentation.

The application users who use these deployed applications are not expected to interact with the Simulink model directly. The Simulink user provides the application user with a tool that allows them to explore task-specific scenarios without looking at the underlying model that represents the dynamic system. The application users can change model parameters and simulation inputs, and record and analyze simulation outputs.

To develop an application, the Simulink user:

  1. Prepares the Simulink model to be compatible with Simulink Compiler, such as checking that the model simulates correctly in rapid accelerator mode. For limitations of rapid accelerator mode and Simulink Compiler, see Simulink Compiler Limitations.


    For information on toolboxes supported by Simulink Compiler, see Toolboxes Supported by Simulink Compiler.

  2. Creates an application that simulates the model using the sim command, in a script or an App designer app.

  3. Configures the script or the app for deployment by using simulink.compiler.configureForDeployment function. The simulink.compiler.configureForDeployment function adapts the model to run in Rapid Accelerator mode.

  4. Creates a standalone application using the mcc command or the deploytool app.

  5. Shares the standalone application.

To use the application, the application user:

  1. Installs MATLAB Runtime environment for the deployed application.

  2. Uses the deployed application.

The following Simulink functions and classes are deployable:



Simulation Pacing in Rapid Accelerator Mode

Using simulation pacing in rapid accelerator mode allows you to use simulation pacing with the deployed standalone executables. You can slow down the simulation of your deployed executable to better visualize simulations and understand system behavior.

To use simulation pacing in rapid accelerator mode, or in the deployed executable, you can use the parameter EnablePacing. To use pacing for a model with the name modelName, use this:

% Enable pacing

%Set pacing rate

Simulation pacing is turned off by default. The EnablePacing and the PacingRate parameters are saved with the model. Use of neither parameters dirties the model. PacingRate must be a non-zero positive integer.

If the model contains a Simulation Pacer block (Aerospace Blockset™), Simulink gives a warning during simulation in the Diagnostic Viewer or the MATLAB prompt. Simulation pacing takes place according to the EnablePacing and PacingRate parameters configuration. The simulation pace set on Simulation Pacer block is ignored.


Simulation pacing is supported in command-line simulations and deployed mode only. In rapid accelerator mode, simulation pacing is not supported in the menu options in the Simulink Editor.
