Xilinx Virtex-II FPGA.

The Virtex-II family is a platform FPGA developed for high frequency clocking. The

leading-edge 0.15µm / 0.12µm CMOS 8-layer metal process and the Virtex-II

architecture are optimized for high speed with low power consumption (1.5 Volts core

voltage).

Virtex-II devices are user-programmable gate arrays with various configurable

elements. The Virtex-II is comprised of

- input/output blocks (IOBs), which can be configured as LVTTL, LVDS

(2.5 and 3.3 Volts), DDR and many other formats.

- internal configurable logic blocks (CLBs). provide functional elements

for combinatorial and synchronous logic, including basic storage

elements. BUFTs (3-state buffers) associated with each CLB element

drive.

- Block SelectRAM memory modules provide large 18-Kbit storage

elements of True Dual-Port RAM.

- Multiplier blocks are 18-bit x 18-bit dedicated multipliers.

- DCM (Digital Clock Manager) blocks provide self-calibrating, fully

digital solutions for clock distribution delay compensation, clock

multiplication and division, coarse and fine-grained clock phase

shifting, and electromagnetic interference (EMI) reduction.

ZBT-RAM Memory.

The SMT377 is populated with 2 independent banks of pipelined ZBT-RAM (Zero

Bus Turnaround), which means that it is optimised for a 100 percent bus utilisation,

eliminating any cycle when transitioning from READ to WRITE or vice versa.

Each bank of memory is 16-bit wide and can store 512Kwords. Both banks are

independently driven by the FPGA, which makes the board capable to store 1 Mega

words of 16 bits.

The default FPGA firmware implement only one ZBTRAM interface.

LEDs.

There 9 green LEDs on the board (see Figure 2 - SMT377 Connectors. for location

on the board):
