Simulink model of a wind turbine
|Stable release||8.1 (part of R2013a) / March 7, 2013|
Simulink, developed by MathWorks, is a data flow graphical programming language tool for modeling, simulating and analyzing multidomain dynamic systems. Its primary interface is a graphical block diagramming tool and a customizable set of block libraries. It offers tight integration with the rest of the MATLAB environment and can either drive MATLAB or be scripted from it. Simulink is widely used in control theory and digital signal processing for multidomain simulation and Model-Based Design.
Add-on products 
A number of MathWorks and third-party hardware and software products are available for use with Simulink. For example, Stateflow extends Simulink with a design environment for developing state machines and flow charts.
Coupled with Simulink Coder, another product from MathWorks, Simulink can automatically generate C source code for real-time implementation of systems. As the efficiency and flexibility of the code improves, this is becoming more widely adopted for production systems, in addition to being a popular tool for embedded system design work because of its flexibility and capacity for quick iteration. Embedded Coder creates code efficient enough for use in embedded systems.
xPC Target together with x86-based real-time systems provides an environment to simulate and test Simulink and Stateflow models in real-time on the physical system. Embedded Coder also supports specific embedded targets, including Infineon C166, Motorola 68HC12, Motorola MPC 555, TI C2000, TI C6000, Renesas V850 and Renesas SuperH.
Simulink Verification and Validation enables systematic verification and validation of models through modeling style checking, requirements traceability and model coverage analysis. Simulink Design Verifier uses formal methods to identify design errors like integer overflow, division by zero and dead logic, and generates test case scenarios for model checking within the Simulink environment.
The systematic testing tool TPT offers one way to perform formal test- verification and validation process to stimulate Simulink models but also during the development phase where the developer generates inputs to test the system. By the substitution of the Constant and Signal generator blocks of Simulink the stimulation becomes reproducible.
SimEvents adds a library of graphical building blocks for modeling queuing systems to the Simulink environment. It also adds an event-based simulation engine to the time-based simulation engine in Simulink.
