  • XAPP694-从配置PROM读取用户数据

    This application note describes how to retrieve user-defined data from Xilinx configurationPROMs (XC18V00 and Platform Flash devices) after the same PROM has configured theFPGA. The method to add user-defined data to the configuration PROM file is also discussed.The reference design described in this application note can be used in any of the followingXilinx FPGA architectures: Spartan™-II, Spartan-IIE, Spartan-3, Virtex™, Virtex-E, Virtex-II,and Virtex-II Pro.

  • XAPP098 - Spartan FPGA低成本、高效率串行配置

    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.

  • WP401-FPGA设计的DO-254

    The standard that governs the design of avioniccomponents and systems, DO-254, is one of the mostpoorly understood but widely applicable standardsin the avionic industry. While information on thegeneral aspects of the standard is easy to obtain, thedetails of exactly how to implement the standard aresketchy. And once an entity develops a process thatachieves compliance, the details of how compliancewas achieved become part of the intellectualproperty of that entity. This white paper focuses onthe details of developing a DO-254 compliantprocess for the design of FPGAs.

  • XAPP806 -决定DDR反馈时钟的最佳DCM相移

    This application note describes how to build a system that can be used for determining theoptimal phase shift for a Double Data Rate (DDR) memory feedback clock. In this system, theDDR memory is controlled by a controller that attaches to either the OPB or PLB and is used inan embedded microprocessor application. This reference system also uses a DCM that isconfigured so that the phase of its output clock can be changed while the system is running anda GPIO core that controls that phase shift. The GPIO output is controlled by a softwareapplication that can be run on a PowerPC® 405 or Microblaze™ microprocessor.
