  • xilinx Zynq-7000 EPP产品简介

    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.

  • FPGA设计重利用方法(Design Reuse Methodology)

      FPGAs have changed dramatically since Xilinx first introduced them just 15 years ago. In thepast, FPGA were primarily used for prototyping and lower volume applications; custom ASICswere used for high volume, cost sensitive designs. FPGAs had also been too expensive and tooslow for many applications, let alone for System Level Integration (SLI). Plus, the development

    解压密码:www.elecfans.com 随着微电子技术的迅速发展以及集成电路规模不断提高,对电路性能的设计 要求越来越严格,这势必对用于大规模集成电路设计的EDA 工具提出越来越高的 要求。自1972 年美国加利福尼亚大学柏克莱分校电机工程和计算机科学系开发 的用于集成电路性能分析的电路模拟程序SPICE(Simulation Program with IC Emphasis)诞生以来,为适应现代微电子工业的发展,各种用于集成电路设计的 电路模拟分析工具不断涌现。HSPICE 是Meta-Software 公司为集成电路设计中 的稳态分析,瞬态分析和频域分析等电路性能的模拟分析而开发的一个商业化通 用电路模拟程序,它在柏克莱的SPICE(1972 年推出),MicroSim公司的PSPICE (1984 年推出)以及其它电路分析软件的基础上,又加入了一些新的功能,经 过不断的改进,目前已被许多公司、大学和研究开发机构广泛应用。HSPICE 可 与许多主要的EDA 设计工具,诸如Candence,Workview 等兼容,能提供许多重要 的针对集成电路性能的电路仿真和设计结果。采用HSPICE 软件可以在直流到高 于100MHz 的微波频率范围内对电路作精确的仿真、分析和优化。在实际应用中, HSPICE能提供关键性的电路模拟和设计方案,并且应用HSPICE进行电路模拟时, 其电路规模仅取决于用户计算机的实际存储器容量。 The HSPICE Integrator Program enables qualified EDA vendors to integrate their products with the de facto standard HSPICE simulator, HSPICE RF simulator, and WaveView Analyzer™. In addition, qualified HSPICE Integrator Program members have access to HSPICE integrator application programming interfaces (APIs). Collaboration between HSPICE Integrator Program members will enable customers to achieve more thorough design verification in a shorter period of time from the improvements offered by inter-company EDA design solutions.

  • 赛灵思电机控制开发套件简介(英文版)

      The power of programmability gives industrial automation designers a highly efficient, cost-effective alternative to traditional motor control units (MCUs)。 The parallel-processing power, fast computational speeds, and connectivity versatility of Xilinx® FPGAs can accelerate the implementation of advanced motor control algorithms such as Field Oriented Control (FOC)。   Additionally, Xilinx devices lower costs with greater on-chip integration of system components and shorten latencies with high-performance digital signal processing (DSP) that can tackle compute-intensive functions such as PID Controller, Clark/Park transforms, and Space Vector PWM.   The Xilinx Spartan®-6 FPGA Motor Control Development Kit gives designers an ideal starting point for evaluating time-saving, proven, motor-control reference designs. The kit also shortens the process of developing custom control capabilities, with integrated peripheral functions (Ethernet, PowerLink, and PCI® Express), a motor-control FPGA mezzanine card (FMC) with built-in Texas Instruments motor drivers and high-precision Delta-Sigma modulators, and prototyping support for evaluating alternative front-end circuitry.

  • 智能照明控制器测量环境光线

    Abstract: This application note explains how to design an intelligent lighting controller that senses and measures the ambient lightlevel with an ambient light sensor (ALS). Equipped with a real-time clock (RTC), the controller also knows when to turn lighting on oroff at specified times. The system presented in this document can be used to control all luminaires that are mains-supply operated.Controller software is also provided in hex format.

      Have you had the exasperating experience of a laptop orPDA defi antly not responding to your commands? Youfrantically press key after key, but to no avail. As hopeturns to anger (but just before you throw the company’slaptop through the window) you slam your fi nger againstthe on/off power button. Ten seconds later, your laptopfi nally surrenders and the screen goes black in a highpitched whimper.

  • 基于Multisim 10的矩形波信号发生器仿真与实现

    在Multisim 10软件环境下,设计一种由运算放大器构成的精确可控矩形波信号发生器,结合系统电路原理图重点阐述了各参数指标的实现与测试方法。通过改变RC电路的电容充、放电路径和时间常数实现了占空比和频率的调节,通过多路开关投入不同数值的电容实现了频段的调节,通过电压取样和同相放大电路实现了输出电压幅值的调节并提高了电路的带负载能力,可作为频率和幅值可调的方波信号发生器。Multisim 10仿真分析及应用电路测试结果表明,电路性能指标达到了设计要求。 Abstract:  Based on Multisim 10, this paper designed a kind of rectangular-wave signal generator which could be controlled exactly composed of operational amplifier, the key point was how to implement and test the parameter indicators based on the circuit diagram. The duty and the frequency were adjusted by changing the time constant and the way of charging and discharging of the capacitor, the width of frequency was adjusted by using different capacitors provided with multiple switch, the amplitude of output voltage was adjusted by sampling voltage and using in-phase amplifier circuit,the ability of driving loads was raised, the circuit can be used as squarewave signal generator whose frequency and amplitude can be adjusted. The final simulation results of Multisim 10 and the tests of applicable circuit show that the performance indicators of the circuit meets the design requirements.
