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.

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。
