Xilinx公司的7系列FPGA产品包括Artix™-7系列, Kintex™-7系列和Virtex&-7系列,具有低成本,小尺寸,高性价比和大容量以及超高端连接带宽,逻辑功能和信号处理能力等特性,适合要求最严格的高性能应用.本文介绍了Xilinx 7系列FPGA主要特性,7系列三种FPGA性能比较表,以及Virtex-7 FPGA主要特性, Virtex-7 FPGA评估板VC707主要特性, 方框图,电路图和材料清单.Xilinx& 7 series FPGAs comprise three new FPGA families that address the complete range of system requirements, ranging from low cost, small form factor, cost-sensitive, high-volume applications to ultra high-end connectivity bandwidth, logic capacity, and signal processing capability for the most demanding high-performance applications. The 7 series devices are the programmable silicon foundation for Targeted Design Platforms that enable designers to focus on innovation from the outset of their development cycle. The 7 series FPGAs include:• Artix™-7 Family: Optimized for lowest cost and power with small form-factor packaging for the highest volume applications.• Kintex™-7 Family: Optimized for best price-performance with a 2X improvement compared to previous generation, enabling a new class of FPGAs.• Virtex&-7 Family: Optimized for highest system performance and capacity with a 2X improvement in system performance. Highest capability devices enabled by stacked silicon interconnect (SSI) technology.Built on a state-of-the-art, high-performance, low-power (HPL), 28 nm, high-k metal gate (HKMG) process technology, 7 series FPGAs enable an unparalleled increase in system performance with 2.9 Tb/s of I/O bandwidth, 2 million logic cell capacity, and 5.3 TMAC/s DSP, while consuming 50% less power than previous generation devices to offer a fully programmable alternative to ASSPs and ASICs. All 7 series devices share a scalable, optimized fourth-generation Advanced Silicon Modular Block (ASMBL™) column-based architecture that reduces system development and deployment time with simplified design portability.Xilinx 7系列FPGA主要特性:• Advanced high-performance FPGA logic based on real 6-input lookup table (LUT) technology configurable as distributed memory.• 36 Kb dual-port block RAM with built-in FIFO logic for on-chip data buffering.• High-performance SelectIO™ technology with support for DDR3 interfaces up to 1,866 Mb/s.• High-speed serial connectivity with built-in multi-gigabit transceivers from 600 Mb/s to maximum rates of 6.6 Gb/s up to 28.05 Gb/s, offering a special low-power mode, optimized for chip-to-chip interfaces.• A user configurable analog interface (XADC), incorporating dual 12-bit 1MSPS analog-to-digital converters with on-chip thermal and supply sensors.• DSP slices with 25 x 18 multiplier, 48-bit accumulator, and pre-adder for high performance filtering, including optimized symmetric coefficient filtering.• Powerful clock management tiles (CMT), combining phase-locked loop (PLL) and mixed-mode clock manager (MMCM) blocks for high precision and low jitter.• Integrated block for PCI Express& (PCIe), for up to x8 Gen3 Endpoint and Root Port designs.• Wide variety of configuration options, including support for commodity memories, 256-bit AES encryption with HMAC/SHA-256 authentication, and built-in SEU detection and correction.• Low-cost, wire-bond, lidless flip-chip, and high signal integrity flipchip packaging offering easy migration between family members in the same package. All packages available in Pb-free and selected packages in Pb option.• Designed for high performance and lowest power with 28 nm, HKMG, HPL process, 1.0V core voltage process technology and 0.9V core voltage option for even lower power.7系列比较表:Virtex&-7 FPGAs are available in -3, -2, -1, and -2L speed grades, with -3 having the highest performance. The -2L devices can operate at either of two VCCINT voltages, 0.9V and 1.0V and are screened for lower maximum static power.When operated at VCCINT = 1.0V, the speed specification of a -2L device is the same as the -2 speed grade. When operated at VCCINT = 0.9V, the -2L performance and static and dynamic power is reduced. The -2G speed grade is available in devices utilizing Stacked Silicon Interconnect Technology. The -2G speed grade supports 12.5 Gb/s GTX,13.1 Gb/s GTH, and 28.05 Gb/s GTZ transceivers as well as the standard -2 speed grade specifications.Virtex-7 FPGA DC and AC characteristics are specified for commercial, extended, and industrial temperature ranges.Except the operating temperature range or unless otherwise noted, all the DC and AC electrical parameters are the same for a particular speed grade (that is, the timing characteristics of a -1 speed grade industrial device are the same as for a -1 speed grade commercial device). However, only selected speed grades and/or devices are available ineach temperature range.All supply voltage and junction temperature specifications are representative of worst-case conditions. The parameters included are common to popular designs and typical applications.Virtex-7 FPGA主要特性:Virtex-7 FPGA评估板VC707The VC707 evaluation board for the Virtex&-7 FPGA provides a hardware environment for developing and evaluating designs targeting the Virtex-7 XC7VX485T-2FFG1761C FPGA. The VC707 board provides features common to many embedded processing systems, including a DDR3 SODIMM memory, an 8-lane PCI Express& interface, a tri-mode Ethernet PHY, general purpose I/O, and two UART interfaces. Other features can be added by using mezzanine cards attached to either of two VITA-57 FPGA mezzanine connectors (FMC) provided on the board. Two high pin count (HPC) FMCs are provided.评估板VC707主要特性:•Virtex-7 XC7VX485T-2FFG1761C FPGA•1 GB DDR3 memory SODIMM&# MB Linear BPI Flash memory•USB 2.0 ULPI Transceiver•Secure Digital (SD) connector•USB JTAG via Digilent module•Clock Generation•Fixed 200 MHz LVDS oscillator (differential)•I2C programmable LVDS oscillator (differential)•SMA connectors (differential)•SMA connectors for GTX transceiver clocking•GTX transceivers•FMC1 HPC connector (eight GTX transceivers)•FMC2 HPC connector (eight GTX transceiver)•SMA connectors (one pair each for TX, RX and REFCLK)•PCI Express (eight lanes)•Small form-factor pluggable plus (SFP+) connector•Ethernet PHY SGMII interface (RJ-45 connector)•PCI Express endpoint connectivity•Gen1 8-lane (x8)•Gen2 8-lane (x8)•SFP+ Connector&#/1000 tri-speed Ethernet PHY•USB-to-UART bridge•HDMI codec•I2C bus•I2C MUX•I2C EEPROM (1 KB)•USER I2C programmable LVDS oscillator•DDR3 SODIMM socket•HDMI codec•FMC1 HPC connector•FMC2 HPC connector•SFP+ connector•I2C programmable jitter-attenuating precision clock multiplier•Status LEDs•Ethernet status•Power good•FPGA INIT•FPGA DONE•User I/O•USER LEDs (eight GPIO)•User pushbuttons (five directional)•CPU reset pushbutton•User DIP switch (8-pole GPIO)•User SMA GPIO connectors (one pair)•LCD character display (16 characters x 2 lines)•• Switches•Power on/off slide switch•Configuration mode DIP switch•VITA 57.1 FMC1 HPC Connector•VITA 57.1 FMC2 HPC Connector•Power management•PMBus voltage and current monitoring via TI power controller•XADC header•Configuration options•Linear BPI Flash memory•USB JTAG configuration port•Platform cable header JTAG configuration port图1.评估板VC707方框图图2.评估板VC707外形图和元件分布图评估板VC707元件分布表:VC707评估板电路图见:VC707评估板材料清单见:详情请见:和

一 系统概述
本评估板采用XILINX常用spartan3芯片进行进行设计，
板上留有JTAG下载电路。
板上集成了XILINX 新一代串行配置芯片XF02S。为了方便用户单独使用这块下载板（也就是作为背板插在自己的目标系统上使用），板上提供了一个50M有源晶振(带晶振插座）
（可按照用户要求选配不同频率有源晶振）。这板由于布线合理，所以能够稳定运行在100M频率以上。我们已经通过扩展连接插座和插头将芯片所有效I/O都已引出，也就是板上（J12,J13,J6,J7)。这样您就可以方便的和您的目标系统配合使用，也就是做为背板使用。这样就算是您的目标系统设计失败或损坏也可以将该板取下插到新的目标系统上面正常使用，这样就缩短了开发时间并降低了研发成本。
板上有一个JTAG插座，这是为了用户对JTAG口进行评估试验所设置。同时我们在板上设置了一个配置芯片选择跳线。如果只是做程序验证，可以将串行PROM屏蔽掉。如果您觉得自己搭电路麻烦或周期比较紧，可以购买我们的EDA底板，我们的已经包含了一般实验所的所有基本外设和相关功能。本评估板是研发人员和大学生进行电子竞赛和相关研究的强有力工具。
