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.

SpartAn-3AN 器件帶有可以用于儲存配置數據的片上Flash 存儲器。如果在您的設計中Flash 存儲器沒有與外部相連，那么Flash 存儲器無法從I/O 引腳讀取數據。由于Flash 存儲器在FPGA 內部，因此配置過程中SpartAn-3AN 器件比特流處于隱藏狀態。這一配置成了設計安全的起點，因為無法直接從Flash 存儲器拷貝設計。

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.

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.
