  • Patent number: 8352239
    Abstract: An interface device for an emulator is disclosed. The interface device includes a connection unit, a transmission unit, and an interface unit. The connection unit receives data, to be used to emulate a logic, from a host computer, and transmits result data, output from the logic, to the host computer. The transmission unit receives the data from the connection unit and stores (writes) the data in the first area of a register array. If the result data is stored in the second area of the register array, the transmission unit reads the result data and transmits the result data to the connection unit. The interface unit includes at least one register array, outputs a clock, set using the data stored in the first area, to the logic, and stores the result data, output from the logic, in the second area.
