To Joerg: If "real RISC5 HW means" an ASIC, then yes.

To Paul: I would also say the FPGA emulates the RISC5 behaviour. But the
behaviour is implemented in HW (= FPGA). The RISC5 Model is
described in verilog, it is compiled/synthesized to a FPGA configuration.

One RISC5 Model is described in C, compiled to some target processor 
(x86, ARM).
That is Peter´s Emulator.

But both are "emulations" of the RISC5  .... rubbish? i hope not.
