Simulation and Model-Based Design

Simulink is an interactive tool for modeling, simulating, and analyzing dynamic, multidomain systems. It lets you accurately describe, simulate, evaluate, and refine a system's behavior through standard and custom block libraries. Simulink models have ready access to MATLAB, providing you with flexible operation and an extensive range of analysis and design tools.

You can use your models for many tasks beyond modeling and simulation via other products. The Simulink Report Generator extracts design information in models into technical documents, and the Real-Time Workshop and Real-Time Workshop Embedded Coder generate highly portable ANSI C and ISO C code from models for use in embedded systems, rapid prototyping, model deployment, and hardware-in-the-loop applications.

Simulink and Stateflow provide an ideal environment for modeling and simulating the behavior of vehicles, drivers, and components such as engines, transmissions, and body electronics modules. You can create your own customized model libraries to coordinate the design process, both within your organization and across OEM-supplier boundaries. These models introduce what is possible using Simulink.
