Honored ContributorWell, really, how about the Altera tutorials?
Trying to understand the HDL files is something of a wasted effort. The actual structure of the code is very different to what you see in SoPC Builder. The idea is that SoPC Builder allows you to think of the interconnection as busses in the conventional sense, but the actual structure of the HDL code is very much more involved than that. So don't bother trying until you are a NIOS/SoPC guru. A good place to start would be the NIOS-II Hardware Development Tutorial, that's where I started. http://www.altera.com/literature/tt/tt_nios2_hardware_tutorial.pdf John
