Overview

The Nexys4-DDR is a drop-in replacement for our cellular RAM-based Nexys boards. Featuring the same Artix-7™ field programmable gate array (FPGA) from Xilinx, the Nexys4-DDR is a ready-to-use digital circuit development platform designed to bring additional industry applications into the classroom environment. With its large, high-capacity FPGA (Xilinx part number XC7A100T-1CSG324C) 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, a temperature sensor, MEMs digital microphone, speaker amplifier and plenty of I/O devices allow the Nexys4-DDR to be used for a wide range of designs without needing any other components. The most notable improvement is the replacement of the 16 MiB CellularRAM with a 128 MiB DDR2 SDRAM memory. Digilent will provide a VHDL reference module that wraps the complexity of a DDR2 controller and is backwards compatible with the asynchronous SRAM interface of the CellularRAM, with certain limitations.

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 450MHz
  • On-chip analog-to-digital converter (XADC)

The Nexys4 DDR also offers an improved collection of ports and peripherals, including:

  • 16 user switches
  • USB-UART Bridge
  • 12-bit VGA output
  • 3-axis accelerometer
  • 128MiB DDR2
  • Pmod for XADC signals
  • 16 user LEDs
  • Two tri-color LEDs
  • PWM audio output
  • Temperature sensor
  • Serial Flash
  • Digilent USB-JTAG port for FPGA programming and communication
  • Two 4-digit 7-segment displays
  • Micro SD card connector
  • PDM microphone
  • 10/100 Ethernet PHY
  • Four Pmod ports
  • 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.

Note: The Nexys4-DDR is not supported by the Digilent Adept Utility.
