and manufacturing information.
Configuration, Status, and Setup Elements
This section describes the board's configuration, status, and setup elements.
Configuration
This section describes the FPGA, flash memory, and MAX II CPLD EPM2210 System
Controller device configuration methods supported by the Cyclone IV GX FPGA
development board. The Cyclone IV GX FPGA development board supports the
following 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.
■ Flash memory download is used for storing FPGA images which the MAX II
CPLD EPM2210 System Controller uses to configure the Cyclone IV GX device
either on board power-up or after the program load push-button switch (S8) is
pressed.
■ External USB-Blaster for configuring the FPGA using an external USB-Blaster.
■ Serial configuration (EPCS) device (U18) is used to store configuration data for
FPGA device that supports active serial (AS) configuration and reloads the data to
the FPGA upon reconfiguration. Use the program select push-button switch (S7) to
select the configuration files to be loaded from either page 0 (factory location),
page 1 (user location), or from the EPCS device.
FPGA Configuration over Embedded USB-Blaster
The USB-Blaster is implemented using a USB Type-B connector (J4), a FTDI USB 2.0
PHY device (U4), and an Altera MAX II CPLD (U7). This allows the configuration of
the FPGA using a USB cable directly connected between the USB port on the board
(J4) and a USB port of a PC running the Quartus II software. The JTAG chain is
normally mastered by the embedded USB-Blaster found in the MAX
II CPLD
EPM2210 System Controller.
