logic emulator
     
        A system of {FPGA}s, programmable interconnect and software
        which automatically configures itself into an operating
        prototype of a large-scale logic design, such as a
        {microprocessor}.  An emulated design can be connected into
        the target system and really operated and tested before the
        design is made into an {integrated circuit}.
     
        {Quickturn} is the leading logic emulation system.
