(i)It provides engineers and students, before actual implementation, with the ability to create virtual prototypes of an entire system and to validate the whole system behavior as early as possible in the development cycle and at different abstraction levels.

Why simulation is needed?

Simulation modeling solves real-world problems safely and efficiently. It provides an important method of analysis which is easily verified, communicated, and understood. ... Unlike physical modeling, such as making a scale copy of a building, simulation modeling is computer based and uses algorithms and equations.

What is simulation and why it is used?

A simulation is the re-creation of a real world process in a controlled environment. It involves creating laws and models to represent the world, and then running those models to see what happens. Simulations are used for scientific exploration, for safety tests, and to create graphics for video games and movies.
