NIOS II SOC Simulation with altera_avalon_mm_master_bfm

I have designed an SOC with NIOS II using QSYS. The design works in HW with SW running. Now, I want to simulate the SOC using the altera_avalon_mm_master_bfm. What I am not clear about is, do I ...

This tutorial describes how to simulate with the BFM

But does not discuss the NIOS processor. But if you have already simulated a system with a NIOS processor, the procedure should be no different. As far as the processor is concerned, so long as it has a clock, reset, and a boot memory, it should just boot as normal.

If you have a NIOS processor, why do you need a Avalon-MM BFM? The NIOS processor is already an Avalon-MM master.

I did run a simulation with the NIOS and some software but it is way too slow to be useful. In the mean time I added the BFM and QSYS did not complain. I just wonder how the BFM and NIOS will co-exist and if NIOS which now has no SW to run on will not interfere with the BFM. Will the BFM be removed in systhesis? The USB-Blaster example is close to what I'm looking for however its the NIOS/BFM combination that I'm after. If it works is should run much faster.

Thanks for your help Dave :-P
