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.

The introduction of Spartan-3™ devices has createdmultiple changes in the evolution of embedded controldesigns and pushed processing capabilities to the “almostfreestage.” With these new FPGAs falling under $20, involume, with over 1 million system gates, and under $5for 100K gate-level units, any design with programmablelogic has a readily available 8- or 16-bit processor costingless than 75 cents and 32-bit processor for less than $1.50.

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.

一些應用利用 Xilinx FPGA 在每次啟動時可改變配置的能力，根據所需來改變 FPGA 的功能。Xilinx Platform Flash XCFxxP PROM 的設計修訂 (Design Revisioning) 功能，允許用戶在單個PROM 中將多種配置存儲為不同的修訂版本，從而簡化了 FPGA 配置更改。在 FPGA 內部加入少量的邏輯，用戶就能在 PROM 中存儲的多達四個不同的修訂版本之間進行動態切換。多重啟動或從多個設計修訂進行動態重新配置的能力，與 Spartan™-3E FPGA 和第三方并行 flashPROM 一起使用時所提供的 MultiBoot 選項相似。本應用指南將進一步說明 Platform Flash PROM 如何提供附加選項來增強配置失敗時的安全性，以及如何減少引腳數量和板面積。此外，Platform Flash PROM 還為用戶提供其他優勢：iMPACT 編程支持、單一供應商解決方案、低成本板設計和更快速的配置加載。本應用指南還詳細地介紹了一個包含 VHDL 源代碼的參考設計。
