In modern engineering, Model-Based Design has become a strategic imperative, enabling teams to simulate, test, and verify complex systems before committing to physical prototypes. This approach accelerates innovation, reduces costs, and improves final product quality. At the heart of this paradigm is Simulink, a premier environment for the simulation and analysis of dynamic and embedded systems.

Simulink is a data flow graphical programming language and a comprehensive model-based design environment that is fully integrated into the MATLAB ecosystem. Developed by MathWorks, it provides a graphical block diagramming interface with an extensive and customizable set of block libraries, allowing engineers and scientists to model, simulate, and analyze multi-domain dynamic systems visually.

The primary applications of Simulink are central to the engineering lifecycle and include:

• System-level design
• Simulation
• Automatic code generation
• Testing and verification of embedded systems

One of Simulink’s core value propositions is its seamless integration with MATLAB. This allows for the direct incorporation of sophisticated MATLAB algorithms into Simulink models and the ability to export simulation results back into the MATLAB environment. This bidirectional data flow creates a powerful workflow for comprehensive post-processing, visualization, and in-depth analysis. This guide will provide a step-by-step walkthrough of the fundamental processes required to leverage this powerful tool, beginning with the initial software setup.
