An '''emulator''' is a piece of hardware which exactly duplicates the functionality of another piece of hardware.

One common form of emulator is an '''In-Circuit Emulator''' (often called by the acronym, '''ICE'''), which is a perfect emulation of a given [[integrated circuit|chip]], down to the physical form, but which has a control unit attached to it which can record the operation of the emulated chip, for diagnostic and debugging purposes.

Generally, an emulator is a unit which exactly duplicates the ''external'', visible functionality of another unit; the term is usually used of hardware, but not always.

	Since emulators usually have an emphasis on duplicating exactly the device's external interface and behaviour, they may often be used in place of the emulated device.
