1 Overview
The Nexys4 DDR board is a complete, ready-to-use digital circuit
development platform based on the latest Artix-7™ Field
Programmable Gate Array (FPGA) from Xilinx®. With its large,
high-capacity FPGA (Xilinx part number XC7A100T-1CSG324C),
generous external memories, and collection of USB, Ethernet, and
other ports, the Nexys4 DDR can host designs ranging from
introductory combinational circuits to powerful embedded
processors. Several built-in peripherals, including an
accelerometer, temperature sensor, MEMs digital microphone, a
speaker amplifier, and several I/O devices allow the Nexys4 DDR
to be used for a wide range of designs without needing any other
components.
The Artix-7 FPGA is optimized for high performance logic, and offers more capacity, higher performance, and more
resources than earlier designs. Artix-7 100T features include:
15,850 logic slices, each with four 6-input LUTs and 8 flip-flops
4,860 Kbits of fast block RAM
Six clock management tiles, each with phase-locked loop (PLL)
240 DSP slices
Internal clock speeds exceeding 450 MHz
On-chip analog-to-digital converter (XADC)
The Nexys4 DDR also offers an improved collection of ports and peripherals, including:
16 user switches
16 user LEDs
Two 4-digit 7-segment displays
USB-UART Bridge
Two tri-color LEDs
Micro SD card connector
12-bit VGA output
PWM audio output
PDM microphone
3-axis accelerometer
Temperature sensor
10/100 Ethernet PHY
128MiB DDR2
Serial Flash
Four Pmod ports
Pmod for XADC signals
Digilent USB-JTAG port for FPGA
programming and
communication
USB HID Host for mice, keyboards
and memory sticks
The Nexys4 DDR is compatible with Xilinx’s new high-performance Vivado®
Design Suite as well as the ISE® toolset,
which includes ChipScope™ and EDK. Xilinx offers free WebPACK™ versions of these toolsets, so designs can be
implemented at no additional cost. The Nexys4 DDR is not supported by the Digilent Adept Utility.
