Well, then it becomes a philosophical question. If it walks like a duck and quacks like a duck..

From an electrical perspective, a 68k implemented in an FPGA might be indistinguishable from a genuine 68k except that the voltage slopes might be different on the FPGA due to it being made a more modern IC process containing faster transistors.

A 68020 is also different from a 68000, and it is probably much less compatible with a regular 68k than the Apollo core since the Apollo core supports self-modifying code while the 020 does not if the coder did not take steps to make it work.

There are plenty of real 68000 CPUs still left out there if that is what you want, but now there is also the Vampire for those who want to their Amigas to do more than what they could 20-30 years ago.
