ABSTRACT:
An emulator system capable of solving a problem of a conventional emulator system in that it requires a gate array for executing a port function of a peripheral emulation chip because external pins of the peripheral emulation chip cannot achieve the port function required in a peripheral emulation mode. The present emulator system has at least two peripheral emulation chips. Each peripheral emulation chip includes a core block for controlling buses, a peripheral function block for achieving functions of a peripheral device, a mode setting circuit for setting a normal mode enabling the core block or the peripheral emulation mode enabling the peripheral function block, external pins, and a link switching circuit for selecting one of the connections of the external pins with the buses and with the peripheral function block.
