    I'm far from being a hardware specialist, but as far as I know, you don't actually load any software into an FPGA. What's essentially happening instead is that during configuration, the FPGA's logic gates are wired according to the behaviour specified in the HDL file. The main difference between ASIC and FPGA is simply the re-configurability of the FPGA's logic gates and their wiring. That's why I wouldn't call it emulation.

    To my mind, even if the Apollo 68080 will be made into an ASIC one day, the older FPGA-based solution won't suddenly turn into an emulation.
