General
Description The Nios development board comes pre-programmed with a Nios II
processor reference design. Hardware designers can use the reference
design as an example of how to build systems using the Nios II processor
and to gain familiarity with the features included. Software designers can
use the pre-programmed Nios II processor design on the board to begin
prototyping software immediately.
This document describes the hardware features of the Nios development
board, including detailed pin-out information, to enable designers to
create custom FPGA designs that interface with all components on the
board. A complete set of schematics, a physical layout database, and
GERBER files for the development board are installed with the Nios II
development tools in the <Nios II EDS install path>/documents directory.
