Examples of Advanced Demonstrations
This chapter provides a number of examples of advanced circuits implemented on the DE2-115
board. These circuits provide demonstrations of the major features on the board, such as its audio
and video capabilities, USB, and Ethernet connectivity. For each demonstration the Cyclone IV E
FPGA (or EPCS64 serial EEPROM) configuration file is provided, as well as the full source code in
Verilog HDL. All of the associated files can be found in the DE2_115_demonstrations folder on the
DE2-115 System CD. For each demonstrations described in the following sections, the name of the
project directory for its files is given, which are subdirectories of the DE2_115_demonstrations
folder.
„ Installing the Demonstrations
To install the demonstrations on your computer:
Copy the directory DE2_115_demonstrations into a local directory of your choice. It is important to
ensure that the path to your local directory contains no spaces – otherwise, the Nios II software will
not work. Note Quartus II v9.1 SP2 is required for all DE2-115 demonstrations to support Cyclone
IV E device. Quartus II v10.0 can be installed from the Altera Complete Design Suite DVD
provided.
6.1 DE2-115 Factory Configuration
The DE2-115 board is shipped from the factory with a default configuration bit-stream that
demonstrates some of the basic features of the board. The setup required for this demonstration, and
the locations of its files are shown below.
„ Demonstration Setup, File Locations, and Instructions
• Project directory: DE2_115_Default
• Bit stream used: DE2_115_Default.sof or DE2_115_Default.pof
• Power on the DE2-115 board, with the USB cable connected to the USB Blaster port. If
necessary (that is, if the default factory configuration of the DE2-115 board is not currently
