I'm far from being a hardware specialist, but as far as I know, you don't actually load any software into an FPGA.
Of course you load software to 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.
VHDL is not one and only language used on FPGA, one may also use special version of C/C++ to compile software used on FPGA.
Logic gates are not magicaly "wired". Metal paths on FPGA not change in magical way.
Just addictional logic work in that or other way depended on SOFTWARE loaded to FPGA memory.

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.
gunnar von boehn has no result, so he fool some people that emulation is not emulation.
The truth about FPGA it is not classical emulator like uae where there is main loop with instruction decoding, but it is still some form of software emulation.
The same FPGA may be today vampire crap, tomorrow may control washing machine.
It only depends on SOFTWARE loaded to FPGA.
