Real time simulation

[ACRTM]

Hi,

Can anyone tell me, what is real time simulation and why it must be used?

Thank you

It's simulation that is at the same rate as reality would be. This, as compared to high speed simulation.

An example of non-realtime would be an astrophysicist who uses a computer simulation to model two stars colliding. They would run the simulation as fast as they can and watch it all occur in a minute or two whereas reality is going to take millions of years.

A realtime example is the Alaskan pipe line. A realtime simulation of the flow is continually running so if 'reality' changes it will be detected and the line can be shut down. A reality change would be a pin hole leak developing somewhere that would cause the actual conditions to change from the predicted simulation.

A real-time simulation might be something done on this

which allows one to run Matlab/Simulink code fast enough to operate hardware in real-time, i.e., hardware-in-the-loop (HIL) simulation.

Often, real-time systems have peripheral events that can affect system performance that cannot be modeled accurately in a simulation, such as resource contention and interrupt service.
