I stand corrected. There indeed is software loaded into the memory of an FPGA. It's just that this software is used to configure the FPGA hardware, not to statically execute (interpret) or dynamically execute (JIT-compile) the programs like an emulator would.

HDL simply means 'hardware description language'. This can be Verilog, AHDL, VHDL, M language
or any other
language suited to describe hardware behaviour.

At least my stance regarding FPGAs has nothing to do with him.

The innards of the FPGA that execute the software are still hardware.

Just like Motorola/Freescale/NXP 680x0, which powered the Amiga and other computers and also has controlled washing machines :-)
