The procedure for downloading a circuit from a host computer to the DE2-115 board is described in
the tutorial Quartus II Introduction. This tutorial is found in the DE2_115_tutorials folder on the
DE2-115 System CD. The user is encouraged to read the tutorial first, and treat the information
below as a short reference.
The DE2-115 board contains a serial configuration device that stores configuration data for the
Cyclone IV E FPGA. This configuration data is automatically loaded from the configuration device
into the FPGA every time while power is applied to the board. Using the Quartus II software, it is
possible to reconfigure the FPGA at any time, and it is also possible to change the non-volatile data
that is stored in the serial configuration device. Both types of programming methods are described
below.

 JTAG Chain on DE2-115 Board
To use JTAG interface for configuring FPGA device, the JTAG chain on DE2-115 must form a
close loop that allows Quartus II programmer to detect FPGA device.

JTAG programming: In this method of programming, named after the IEEE standards Joint
Test Action Group, the configuration bit stream is downloaded directly into the Cyclone IV E
FPGA. The FPGA will retain this configuration as long as power is applied to the board; the
configuration information will be lost when the power is turned off.
AS programming: In this method, called Active Serial programming, the configuration bit
stream is downloaded into the Altera EPCS64 serial configuration device. It provides
non-volatile storage of the bit stream, so that the information is retained even when the power
supply to the DE2-115 board is turned off. When the board‟s power is turned on, the
configuration data in the EPCS64 device is automatically loaded into the Cyclone IV E FPGA.
