well.. this is a stupid question, but i wanna ask anyway..

So you could actually create something using SOPC without implementing a NIOS 2 processor? I thought the whole purpose of using SOPC is to implement a design with a NIOS 2?

Its not a stupid question. All the documentation relating to SOPC/Qsys generally talk about NIOS II systems. However, all you really need is an Avalon-MM bus master. The NIOS II just happens to be one type of master.

I rarely use the NIOS II processor. I use the JTAG-to-Avalon-MM bridge for debugging, and then have other processor-to-Avalon-MM master designs for accessing components inside the FPGA.

Cheers,
