Stratix IV GT Edition Reference Manual
Configuration, Status, and Setup Elements
This section describes the board’s configuration, status, and setup elements.
Configuration
The Stratix IV GT transceiver signal integrity development board supports three
configuration methods:
■ Embedded USB-Blaster is the default method for configuring the FPGA at any
time using the Quartus II Programmer in JTAG mode with the supplied USB cable.
■ MAX II+Flash FPP download for configuring the FPGA using stored images from
flash on either power-up or pressing the reset (SW8) push button.
■ JTAG programming header (J28) for configuring the FPGA using an external
USB-Blaster (not supplied) and the Quartus II Programmer.
The following sections describe each of these methods.
Embedded USB-Blaster
The embedded USB-Blaster is implemented using a Type-B USB connector (CN1), a
Future Technologies FT245BL USB PHY device (U16), and an Altera EPM7064 MAX II
CPLD (U17). This allows the configuration of the FPGA using a USB cable directly
connected between the USB port on the board (CN1) and a USB port of a PC running
the Quartus II software.
