Examples of Advanced Demonstrations<br />
This chapter provides a number of examples of advanced circuits implemented on the <strong>DE2</strong>-<strong>115</strong><br />
board. These circuits provide demonstrations of the major features on the board, such as its audio<br />
and video capabilities, USB, and Ethernet connectivity. For each demonstration the Cyclone IV E<br />
FPGA (or EPCS64 serial EEPROM) configuration file is provided, as well as the full source code in<br />
Verilog HDL. All of the associated files can be found in the <strong>DE2</strong>_<strong>115</strong>_demonstrations folder on the<br />
<strong>DE2</strong>-<strong>115</strong> System CD. For each demonstrations described in the following sections, the name of the<br />
project directory for its files is given, which are subdirectories of the <strong>DE2</strong>_<strong>115</strong>_demonstrations<br />
folder.<br />
• Installing the Demonstrations<br />
To install the demonstrations on your computer:<br />
Copy the directory <strong>DE2</strong>_<strong>115</strong>_demonstrations into a local directory of your choice. It is important to<br />
ensure that the path to your local directory contains no spaces – otherwise, the Nios II software will<br />
not work. Note Quartus II v9.1 SP2 is required for all <strong>DE2</strong>-<strong>115</strong> demonstrations to support Cyclone<br />
IV E device. Quartus II v10.0 can be installed from the Altera Complete Design Suite DVD<br />
provided.<br />
6.1 <strong>DE2</strong>-<strong>115</strong> Factory Configuration<br />
The <strong>DE2</strong>-<strong>115</strong> board is shipped from the factory with a default configuration bit-stream that<br />
demonstrates some of the basic features of the board. The setup required for this demonstration, and<br />
the locations of its files are shown below.<br />
