Run on Target Hardware

This flow shows how Simulink Coder takes a Simulink model, generates C code, and deploys it to hardware.

Execution Sample

Simulink

1. Open Simulink model
2. Set code generation parameters
3. Click 'Build' to generate code
4. Review generated C files
5. Deploy code to hardware

This sequence shows the main steps to generate and deploy C code from a Simulink model using Simulink Coder.

Execution Table

Step	Action	Input/Settings	Output/Result
1	Open Simulink model	Model file (.slx)	Model loaded in Simulink environment
2	Configure code generation	Select target, optimization, and options	Code generation settings saved
3	Build model	Click build button	C code files generated in folder
4	Review code	Open generated .c and .h files	Code matches model behavior
5	Deploy code	Use build tools or IDE	Code runs on target hardware

💡 All steps complete, code generated and deployed successfully

Variable Tracker

Variable	Start	After Step 2	After Step 3	After Step 5
Simulink Model	Not loaded	Loaded	Loaded	Loaded
Code Generation Settings	Default	Configured	Configured	Configured
Generated Code	None	None	Available	Deployed
Hardware Status	Idle	Idle	Idle	Running

Key Moments - 3 Insights

Why do we need to configure code generation settings before building?

Because the settings tell Simulink Coder how to generate code, like target hardware and optimization. See execution_table step 2.

What happens if the model is not loaded before building?

The build will fail because there is no model to convert. Step 1 must be done first as shown in execution_table.

How do we know the generated code matches the model?

By reviewing the generated .c and .h files in step 4, you can check the code structure and comments.

Visual Quiz - 3 Questions

Look at the execution table, what is the output after step 3?

A Code generation settings saved

B C code files generated in folder

C Model loaded in Simulink environment

D Code runs on target hardware

💡 Hint

Check the 'Output/Result' column for step 3 in the execution_table.

At which step does the hardware start running the code?

A Step 2

B Step 3

C Step 5

D Step 4

💡 Hint

Look at the 'Output/Result' column for step 5 in the execution_table.

If the model is not loaded, what will be the status of 'Simulink Model' variable after step 1?

A Loaded

B Configured

C Not loaded

D Deployed

💡 Hint

Refer to variable_tracker row for 'Simulink Model' at 'After Step 2'.

Full Transcript

Simulink Coder is a tool that converts Simulink models into C code. First, you open your model in Simulink. Then, you set up code generation options like target hardware and optimization. Next, you build the model which generates C code files. After that, you review the generated code to ensure it matches your model. Finally, you deploy the code to your hardware and run it. This flow helps turn your designs into working embedded software.
