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 器件带有可以用于储存配置数据的片上Flash 存储器。如果在您的设计中Flash 存储器没有与外部相连,那么Flash 存储器无法从I/O 引脚读取数据。由于Flash 存储器在FPGA 内部,因此配置过程中spartan-3AN 器件比特流处于隐藏状态。这一配置成了设计安全的起点,因为无法直接从Flash 存储器拷贝设计。

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.
