Emulation addresses the original hardware and software environment of the digital object, and recreates it on a current machine. [9] The emulator allows the user to have access to any kind of application or operating system on a current platform, while the software runs as it did in its original environment. [10]
Because the results of a simulation are only as good as the underlying model(s), engineers, operators, and analysts must pay particular attention to its construction. To ensure that the results of the simulation are applicable to the real world, the user must understand the assumptions, conceptualizations, and constraints of its implementation.
Hybrid simulation (or combined simulation) corresponds to a mix between continuous and discrete event simulation and results in integrating numerically the differential equations between two sequential events to reduce the number of discontinuities. [10] A stand-alone simulation is a simulation running on a single workstation by itself.
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.
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.
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 ...
Surrogate models are constructed using a data-driven, bottom-up approach. The exact, inner working of the simulation code is not assumed to be known (or even understood), relying solely on the input-output behavior. A model is constructed based on modeling the response of the simulator to a limited number of intelligently chosen data points.
