Emulate
Verb
1. Strive to equal or match, especially by imitating; “He is emulating the skating skills of his older sister”.
2. Imitate the function of (another system), as by modifying the hardware or the software; in computer science.
3. Compete with successfully; approach or reach equality with; “This artists’s drawings cannot emulate his water colors”.

在计算机领域的特殊含义如下：
To imitate one system with another, primarily by hardware, so that the imitating system accepts the same data, executes the same computer programs, and achieves the same results as the imitated system

Simulator
Noun
1. A machine that simulates an environment for the purpose of training or research.
在计算机领域的特殊含义如下：
A device, data processing system, or computer program for representing features of the behavior of a physical or abstract system.

维基百科（英）
emulator
An emulator in computer sciences duplicates (provides an emulation of) the functions of one system using a different system, so that the second system behaves like (and appears to be) the first system. This focus on exact reproduction of external behavior is in contrast to some other forms of computer simulation, which can concern an abstract model of the system being simulated.

Computer simulator
In computer science, a simulator is a software program to model a real-life situation on a computer so that it can be studied to see how the system behaves. By changing variables, performance predictions may be made about the behaviour of the system. A computer simulator can be either an Instruction Set Simulator or a full system simulator
