Previously known as the Nexys 4 DDR
The Nexys A7 is the new name for our popular Nexys 4 DDR board, now available in two FPGA densities! Featuring the same Artix™-7 field programmable gate array (FPGA) from Xilinx®, the Nexys A7 is a ready-to-use digital circuit development platform designed to bring additional industry applications into the classroom environment. The Artix-7 FPGA is optimized for high-performance logic, and offers more capacity, higher performance, and more resources than earlier designs. With its large, high-capacity FPGA and collection of USB, Ethernet, and other ports, the Nexys A7 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 Nexys A7 to be used for a wide range of designs without needing any other components.
The Nexys A7-100T is compatible with Xilinx's Vivado® Design Suite as well as the ISE® toolset, which includes ChipScope™ and EDK. Xilinx ISE has been discontinued in favor of Vivado® Design Suite.
The Nexys A7-50T variant is compatible only with Vivado® Design Suite.
Xilinx offers free WebPACK™ versions of these toolsets, so designs can be implemented at no additional cost.
The Nexys A7 is not supported by the Digilent Adept Utility.
