Human-in-the-loop simulation of outer space Visualization of a direct numerical simulation model. Historically, simulations used in different fields developed largely independently, but 20th-century studies of systems theory and cybernetics combined with spreading use of computers across all those fields have led to some unification and a more systematic view of the concept.
While emulation could, if taken to the extreme, go down to the atomic level, basing its output on a simulation of the actual circuitry from a virtual power source, this would be a highly unusual solution. Emulators typically stop at a simulation of the documented hardware specifications and digital logic.
Ikos NSIM-64 Hardware simulation accelerator. In integrated circuit design, hardware emulation is the process of imitating the behavior of one or more pieces of hardware (typically a system under design) with another piece of hardware, typically a special purpose emulation system.
Simulation technology belongs to the tool set of engineers of all application domains and has been included in the body of knowledge of engineering management. M&S helps to reduce costs, increase the quality of products and systems, and document and archive lessons learned. Because the results of a simulation are only as good as the underlying ...
This step brings a lot of uncertainties because the real hardware is normally not as ideal as the simulation model. The differences between real world and simulation are a major reason why emulation is used in hardware design. Generally the simulation and emulation environment are two independent systems. Semulation is a symbiosis of both methods.
Behavioral simulation – high-level simulation of a design's architectural operation, accurate at cycle-level or interface-level. Hardware emulation – Use of special purpose hardware to emulate the logic of a proposed design. Can sometimes be plugged into a system in place of a yet-to-be-built chip; this is called in-circuit emulation.
Gaussian process emulator, a special case of the Gaussian process in statistics; Surrogate model, a model which imitates or emulates a more complicated (usually in terms of computer simulation time) model. ASC Emulation, a football club in Martinique; Emulation (observational learning), a theory of comparative psychology
A 48-hour computer simulation of Typhoon Mawar using the Weather Research and Forecasting model Process of building a computer model, and the interplay between experiment, simulation, and theory Computer simulation is the running of a mathematical model on a computer , the model being designed to represent the behaviour of, or the outcome of, a ...
