What Is Simulink?

In this video, you will get an overview of Simulink^®, a multi-domain modeling and simulation environment for engineers and scientists who design controls, wireless, and other dynamic systems. With Simulink, you can design and simulate systems before moving to hardware, and you can explore and implement new designs without having to write C, C++, or HDL code.

Simulink is the platform for Model-Based Design that supports system-level design, simulation, automatic code generation, and continuous test and verification of embedded systems.

Key capabilities include:

A graphical editor for modeling all components of a system
A library of prebuilt blocks for modeling algorithms and physical systems
Large-scale modeling blocks for creating reusable system components and libraries
A simulation engine with ODE solvers for verifying that all parts of the system work together
Visualization tools for analyzing and comparing results from multiple simulations

Intelligent systems drive the technology of daily life. But how do you implement these systems efficiently and with high quality? For example, a wind turbine adapts to wind conditions to optimize power generation. To make this happen, you need to control blade pitch and yaw, determine gear train sizing, and match electrical demand.

These interconnected components need to be designed together. With Simulink, you can understand and analyze complex systems by simulating block diagrams. To simulate your model, simply press the Run button. The state-of-the-art solvers in Simulink support the simulation of a broad range of analog, digital, mixed signal, and multi-rate systems.

You can easily scale up at thousands or even millions of simulations for parameter sweeping or complex design space exploration. You can configure your model to have just the right amount of detail for your task. For example, you can use an ideal actuator model to determine sizing requirements, and then switch to a model with hydraulic components to design your embedded software.

You can analyze the performance of your algorithm as it evolves to meet your specifications. Simulink add-on products provide additional capabilities from Model-Based Design that allow you to define the system architecture, model physical systems, account for latency and other network effects, and include complex logic in your design. You can improve your design efficiency using tools specific to controls, signal processing, and communications applications.

From the model, you can generate code to prototype and test in real time, and deploy onto an embedded system. Throughout this development process, you continuously verify and validate the design. Model-Based Design with Simulink is transforming the way engineers work.
