Hi wh,

I think those files come from or are (at least) related to AN-333, which you can find here (http://www.altera.com/literature/lit-an.jsp). Reads/Writes (in C) translate into transactions between masters (like the Nios II) and slaves (like the PWM component) on the Avalon-MM "bus". The HDL (VHDL in your case) then translates these transactions into "actions" in your hardware.

Reading the AN-333 document will help you to understand this better.

Cheers, and Enjoy!
