Creating and Working with Models

With Simulink, you can quickly create, model, and maintain a detailed block diagram of your system using a comprehensive set of predefined blocks. Simulink provides tools for hierarchical modeling, data management, and subsystem customization, making it easy to create concise, accurate representations, regardless of your system’s complexity.

Selecting and Customizing Blocks
Simulink includes more than 200 blocks that implement functions commonly used in modeling a system. These include:
1. Continuous and discrete dynamics blocks, such as integration and unit delay
2. Algorithmic blocks, such as sum, product, and lookup tables
3. Structural blocks, such as mux, switch, and signal and bus selectors
You can customize these built-in blocks or create your own. Additional blocksets (available separately) extend Simulink with specific functionality for aerospace, communications, signal processing, and other applications.

You can model physical systems in Simulink. SimMechanics and SimPowerSystems (available separately) provide expanded capabilities for modeling mechanical and electrical systems, respectively.

The Library Browser makes it easy to navigate through standard, add-on, or custom block libraries and drag and drop selected blocks into your model. Click on image to see enlarged view.
