Introduction

The Basys2 board is a circuit design and

implementation platform that anyone can use

to gain experience building real digital circuits.

Built around a Xilinx Spartan-3E Field

Programmable Gate Array and a Atmel

AT90USB2 USB controller, the Basys2 board

provides complete, ready-to-use hardware

suitable for hosting circuits ranging from basic

logic devices to complex controllers. A large

collection of on-board I/O devices and all

required FPGA support circuits are included,

so countless designs can be created without

the need for any other components.

Four standard expansion connectors allow

designs to grow beyond the Basys2 board

using breadboards, user-designed circuit

boards, or Pmods (Pmods are inexpensive

analog and digital I/O modules that offer A/D

& D/A conversion, motor drivers, sensor

inputs, and many other features). Signals on

the 6-pin connectors are protected against

ESD damage and short-circuits, ensuring a

long operating life in any environment. The

Basys2 board works seamlessly with all

versions of the Xilinx ISE tools, including the free WebPack. It ships with a USB cable that provides

power and a programming interface, so no other power supplies or programming cables are required.

The Basys2 board can draw power and be programmed via its on-board USB2 port. Digilent’s freely

available PC-based Adept software automatically detects the Basys2 board, provides a programming

interface for the FPGA and Platform Flash ROM, and allows user data transfers (see

www.digilentinc.com

for more information).

The Basys2 board is designed to work with the free ISE WebPack CAD software from Xilinx.

WebPack can be used to define circuits using schematics or HDLs, to simulate and synthesize

circuits, and to create programming files. Webpack can be downloaded free of charge from

www.xilinx.com/ise/

The Basys2 board ships with a built-in self-test/demo stored in its ROM that can be used to test all

board features. To run the test, set the Mode Jumper (see below) to ROM and apply board power. If

the test is erased from the ROM, it can be downloaded and reinstalled at any time. See

www.digilentinc.com/Basys2

for the test project as well as further documentation, reference designs,

and tutorials.
