Simulink Is for Model-Based Design
From concept to operation
To transform development of complex systems, market-leading companies adopt Model-Based Design by systematically using models throughout the entire process.
- Use a virtual model to simulate and test your system early and often
- Validate your design with physical models, Hardware-in-the-Loop testing, and rapid prototyping
- Generate production-quality C, C++, CUDA, PLC, Verilog, and VHDL code and deploy directly to your embedded system
- Maintain a digital thread with traceability through requirements, system architecture, component design, code and tests
- Extend models to systems in operation to perform predictive maintenance and fault analysis
Simulink Is for Simulation
Design and simulate your system before moving to hardware
Explore a wide design space and test your systems early with multidomain modeling and simulation.
- Quickly evaluate multiple design ideas in one multidomain simulation environment
- Simulate large-scale system models with reusable components and libraries including specialized, third-party modeling tools
- Deploy simulation models for desktop, real-time, and Hardware-in-the-Loop testing
- Run large simulations on multicore desktops, clusters, and the cloud
Simulink Is for Model-Based Systems Engineering
Design, analyze, and test system and software architectures
Model-based systems engineering (MBSE) is the application of models to support the full system lifecycle. Simulink bridges development from requirements and system architecture to detailed component design, implementation, and testing.
- Capture and decompose requirements
- Define and elaborate specifications for components, compositions, and architectures
- Establish a single-source for architecture and component-level interfaces
- Perform analysis and trade studies using MATLAB
- Validate requirements and verify system architectures using simulation-based tests
Simulink Is for Agile Software Development
Agile software development helps teams deliver value to their customers faster using short iteration cycles with an emphasis on continuous integration and team collaboration. Simulation, automated testing, and code generation shorten the development cycle, enabling you to become a successful Agile team.
- Develop and run simulation tests in an automation server to continuously verify new design iterations
- Perform more analysis and testing on the desktop before going to hardware
- Deliver working software through simulations that customers can evaluate
- Respond to changing requirements quicky through model updates and simulation
- Make progress visible to key stakeholders with automated reports and dashboards
Simulink Is for MATLAB Users
Use MATLAB and Simulink together to combine the power of textual and graphical programming in one environment.
Apply your MATLAB knowledge to:
- Optimize parameters
- Create new blocks
- Write tests and automation scripts
- Run thousands of simulations in parallel
- Analyze simulation results
“Simulink is particularly helpful in two stages of our development process. Early on, it helps us try new ideas and visualize how they will work. After generating code and conducting in-vehicle tests, we can run multiple simulations, refine the design, and regenerate code for the next iteration.”
Simulink FAQs
Simulink is a block diagram environment used to design systems with multidomain models, simulate before moving to hardware, and deploy without writing code.
Simulink is used for Model-Based Design, enabling you to design, simulate, and test complex systems across multiple domains, validate designs with Hardware-in-the-Loop testing, and generate production-quality code for embedded systems.
Model-Based Design is a systematic approach that uses models throughout the development process, from concept to operation, enabling you to simulate and test systems early, validate designs, and generate code while maintaining traceability between design artifacts.
Simulink works together with MATLAB, allowing you to combine textual and graphical programming in one environment to optimize parameters, simulate behavior over time, write tests and automation scripts, and analyze simulation results.
There are two main ways to use generative AI with Simulink. Simulink Copilot can explain models, troubleshoot errors, and offer design guidance. Simulink Agentic Toolkit with MATLAB MCP Core Server facilitates iterative design workflows with external AI agents. Model‑Based Design helps ensure designs created with generative AI tools are reliable and ready for real‑world use.
Simulink is used to model and simulate dynamic systems, including control systems, electrification, autonomous systems, robotics, signal processing, wireless communications, and artificial intelligence applications.
Simulink supports testing and verification through desktop simulation, automated tests, SIL, PIL, and HIL workflows, to help engineers detect issues early and verify software before deployment.
Simulink enables automation of simulation, testing, and code generation, allowing teams to run verification workflows in CI/CD pipelines. Tests, model checks, and validation can run on every change to detect issues early, prevent regressions, and accelerate delivery while maintaining traceability and compliance.
Yes, Simulink generates production-quality C, C++, CUDA, PLC, Verilog, and VHDL code that can be deployed directly to embedded systems without writing code manually.
