This application note shows how a Xilinx CoolRunnerTM-II CPLD can be used as a simplelogical switch that can quickly and reliably select between different MPEG video sources. Thesource code for the design is available on the Xilinx website, and is linked from the “VHDLCode” section. The code can be expanded by the user to perform additional operations usingthe remaining CPLD resources

Xilinx FPGAs require at least two power supplies: VCCINTfor core circuitry and VCCO for I/O interface. For the latestXilinx FPGAs, including Virtex-II Pro, Virtex-II and Spartan-3, a third auxiliary supply, VCCAUX may be needed. Inmost cases, VCCAUX can share a power supply with VCCO.The core voltages, VCCINT, for most Xilinx FPGAs, rangefrom 1.2V to 2.5V. Some mature products have 3V, 3.3Vor 5V core voltages. Table 1 shows the core voltagerequirement for most of the FPGA device families. TypicalI/O voltages (VCCO) vary from 1.2V to 3.3V. The auxiliaryvoltage VCCAUX is 2.5V for Virtex-II Pro and Spartan-3, andis 3.3V for Virtex-II.

Xilinx Next Generation 28 nm FPGA Technology Overview Xilinx has chosen 28 nm high-κ metal gate (HKMG) highperformance,low-power process technology and combined it with a new unified ASMBL™ architecture to create a new generation of FPGAs that offer lower power and higher performance. These devices enable unprecedented levels of integration and bandwidth and provide system architects and designers a fully programmable alternative to ASSPs and ASICs.

The Xilinx Zynq-7000 Extensible Processing Platform (EPP) redefines the possibilities for embedded systems, giving system and software architects and developers a flexible platform to launch their new solutions and traditional ASIC and ASSP users an alternative that aligns with today’s programmable imperative. The new class of product elegantly combines an industrystandard ARMprocessor-based system with Xilinx 28nm programmable logic—in a single device. The processor boots first, prior to configuration of the programmable logic. This, along with a streamlined workflow, saves time and effort and lets software developers and hardware designers start development simultaneously.

目前,大型设计一般推荐使用同步时序电路。同步时序电路基于时钟触发沿设计,对时钟的周期、占空比、延时和抖动提出了更高的要求。为了满足同步时序设计的要求,一般在FPGA设计中采用全局时钟资源驱动设计的主时钟,以达到最低的时钟抖动和延迟。 FPGA全局时钟资源一般使用全铜层工艺实现,并设计了专用时钟缓冲与驱动结构,从而使全局时钟到达芯片内部的所有可配置单元(CLB)、I/O单元 (IOB)和选择性块RAM(Block Select RAM)的时延和抖动都为最小。为了适应复杂设计的需要,Xilinx的FPGA中集成的专用时钟资源与数字延迟锁相环(DLL)的数目不断增加,最新的 Virtex II器件最多可以提供16个全局时钟输入端口和8个数字时钟管理模块(DCM)。与全局时钟资源相关的原语常用的与全局时钟资源相关的Xilinx器件原语包括:IBUFG、IBUFGDS、BUFG、BUFGP、BUFGCE、 BUFGMUX、BUFGDLL和DCM等,如图1所示。
