This application note provides users with a general understanding of the SVF and XSVF fileformats as they apply to Xilinx devices. Some familiarity with IEEE STD 1149.1 (JTAG) isassumed. For information on using Serial Vector Format (SVF) and Xilinx Serial Vector Format(XSVF) files in embedded programming applications

This application note provides a detailed description of the Spartan™-3 configurationarchitecture. It explains the composition of the bitstream file and how this bitstream isinterpreted by the configuration logic to program the part. Additionally, a methodology ispresented that will guide the user through the readback process. This information can be usedfor partial reconfiguration or partial readback.

This application note shows how to achieve low-cost, efficient serial configuration for Spartan FPGA designs. The approachrecommended here takes advantage of unused resources in a design, thereby reducing the cost, part count, memory size,and board space associated with the serial configuration circuitry. As a result, neither processor nor PROM needs to be fullydedicated to performing Spartan configuration.In particular, information is provided on how the idle processing time of an on-board controller can be used to loadconfiguration data from an off-board source. As a result, it is possible to upgrade a Spartan design in the field by sending thebitstream over a network.

Consumer display applications commonly use high-speed LVDS interfaces to transfer videodata. Spread-spectrum clocking can be used to address electromagnetic compatibility (EMC)issues within these consumer devices. This application note uses Spartan®-6 FPGAs togenerate spread-spectrum clocks using the DCM_CLKGEN primitive.

Xilinx Next Generation 28 nm FPGA Technology Overview Xilinx has chosen 28 nm high-κ metal gate (HKMG) highperformance,low-power process technology and combined it with a new unified ASMBL™ architecture to create a new generation of FPGAs that offer lower power and higher performance. These devices enable unprecedented levels of integration and bandwidth and provide system architects and designers a fully programmable alternative to ASSPs and ASICs.

The Xilinx Zynq-7000 Extensible Processing Platform (EPP) redefines the possibilities for embedded systems, giving system and software architects and developers a flexible platform to launch their new solutions and traditional ASIC and ASSP users an alternative that aligns with today’s programmable imperative. The new class of product elegantly combines an industrystandard ARMprocessor-based system with Xilinx 28nm programmable logic—in a single device. The processor boots first, prior to configuration of the programmable logic. This, along with a streamlined workflow, saves time and effort and lets software developers and hardware designers start development simultaneously.

一些应用利用 Xilinx FPGA 在每次启动时可改变配置的能力，根据所需来改变 FPGA 的功能。Xilinx Platform Flash XCFxxP PROM 的设计修订 (Design Revisioning) 功能，允许用户在单个PROM 中将多种配置存储为不同的修订版本，从而简化了 FPGA 配置更改。在 FPGA 内部加入少量的逻辑，用户就能在 PROM 中存储的多达四个不同的修订版本之间进行动态切换。多重启动或从多个设计修订进行动态重新配置的能力，与 Spartan™-3E FPGA 和第三方并行 flashPROM 一起使用时所提供的 MultiBoot 选项相似。本应用指南将进一步说明 Platform Flash PROM 如何提供附加选项来增强配置失败时的安全性，以及如何减少引脚数量和板面积。此外，Platform Flash PROM 还为用户提供其他优势：iMPACT 编程支持、单一供应商解决方案、低成本板设计和更快速的配置加载。本应用指南还详细地介绍了一个包含 VHDL 源代码的参考设计。
