Simulink

Simulink is a MATLAB-based graphical programming environment for modeling, simulating and analyzing multidomain dynamical systems. Its main interface is a graphical block diagramming tool together with a customizable set of block libraries, and it is tightly integrated with the rest of the MATLAB environment: it can drive MATLAB or be scripted from it. It is widely used in automatic control and digital signal processing for multidomain simulation and model-based design. MathWorks and third parties sell add-on products for it. Stateflow adds state machines and flow charts, Simscape adds physical modeling of electrical, mechanical, thermal and fluid systems, SimEvents adds queuing models with an event-based engine, and verification products check models for design errors. Coupled with other tools Simulink can generate C source code, and with Embedded Coder code efficient enough for embedded systems, and it can generate synthesizable VHDL and Verilog.
