Simulink is a MATLAB-based graphical programming environment for modeling, simulating and analyzing multidomain dynamical 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 automatic control and digital signal processing for multidomain simulation and model-based design.{{cite web | url = http://www.vega-group.com/assets/documents/10000421matlabsimulink.pdf | title = The Successful development process with MATLAB Simulink in the framework of ESA's ATV project | publisher = Vega Group PLC | access-date = 2011-11-01 | url-status = dead | archive-url = https://web.archive.org/web/20110717191512/http://www.vega-group.com/assets/documents/10000421matlabsimulink.pdf | archive-date = 2011-07-17 }}{{cite journal|url=http://papers.sae.org/2010-01-1999/|title=Model Based Design Accelerates the Development of Mechanical Locomotive Controls|website=sae.org|series=SAE Technical Paper Series |date=2010 |doi=10.4271/2010-01-1999 |access-date=28 June 2015 |last1=Reedy |first1=John |last2=Lunzman |first2=Stephen |volume=1 }}

Add-on products

MathWorks and other third-party hardware and software products can be used with Simulink. For example, Stateflow extends Simulink with a design environment for developing state machines and flow charts.

Coupled with another of their products,{{cite web|url=http://www.mathworks.com/products/simulink-coder?s_cid=wiki_simulink_3|title=Automatic Code Generation - Simulink Coder|work=mathworks.com|access-date=28 June 2015}} 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,[http://ti.arc.nasa.gov/m/pub-archive/1296h/1296%20(Denney).pdf A Software Safety Certification Plug-in for Automated Code Generators: Feasibility Study and Preliminary Design]{{cite web|url=http://www.greencarcongress.com/2009/10/general-motors-developed-twomode-hybrid-powertrain-with-mathworks-modelbased-design-cut-24-months-of.html|title=Green Car Congress: General Motors Developed Two-Mode Hybrid Powertrain With MathWorks Model-Based Design; Cut 24 Months Off Expected Dev Time|author=BioAge Media|work=greencarcongress.com|access-date=28 June 2015}} in addition to being a tool for embedded system design work because of its flexibility and capacity for quick iteration{{citation needed|date=April 2015}}. Embedded Coder creates code efficient enough for use in embedded systems.[http://www.techsource.com.sg/eresources/eres_storyDetails.asp?stid=10 Lotus Engineering Develops Control Systems Software to Reduce Diesel Emissions] {{Archive url|url=https://web.archive.org/web/20060223102856/http://www.techsource.com.sg/eresources/eres_storyDetails.asp?stid=10|date=2006-02-23}}[http://www.cedes.se/Registrerade%20dokument/17%20RH%20JN%20A%20comparison%20of%20code%20generators.pdf A Comparison of Three Code Generators for Models Created in Simulink] {{webarchive|url=https://web.archive.org/web/20100811055925/http://www.cedes.se/Registrerade%20dokument/17%20RH%20JN%20A%20comparison%20of%20code%20generators.pdf |date=2010-08-11 }}{{cite web|url=http://www.automotivedesignline.com/howto/193300307|archive-url=https://web.archive.org/web/20071018215921/http://automotivedesignline.com/howto/193300307|url-status=dead|archive-date=18 October 2007|title=Multitarget modeling reduces ECU software costs|work=EETimes|access-date=28 June 2015}}

Simulink Real-Time (formerly known as xPC Target), together with x86-based real-time systems, is an environment for simulating and testing Simulink and Stateflow models in real-time on the physical system. Another MathWorks product{{cite web|url=http://www.mathworks.com/products/embedded-coder?s_cid=wiki_simulink_5|title=Code Generation - Embedded Coder - Simulink|work=mathworks.com|access-date=28 June 2015}} also supports specific embedded targets. When used with other generic products,[http://www.mathworks.com/products/slhdlcoder?s_cid=wiki_simulink_6 HDL Coder] Simulink and Stateflow can automatically generate synthesizable VHDL and Verilog{{citation needed|date=April 2015}}.

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.

SimEvents is used to add a library of graphical building blocks for modeling queuing systems to the Simulink environment, and to add an event-based simulation engine to the time-based simulation engine in Simulink.{{cite web|title=Introduction to Discrete-Event Simulation | last=Cassandras| first=Christos | publisher= Springer US | date=2007-11-27 | url=http://www.springerlink.com/content/g82w56/?v=editorial| archive-url=https://archive.today/20130202230246/http://www.springerlink.com/content/g82w56/?v=editorial| url-status=dead| archive-date=2013-02-02| access-date=2009-11-03}}
