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。
