可编程逻辑 Xilinx FPGA集成电路的动态老化试验
3 FPGA设计流程
完整的FPGA 设计流程包括逻辑电路设计输入、功能仿真、综合及时序分析、实现、加载配置、调试。FPGA 配置就是将特定的应用程序设计按FPGA设计流程转化为数据位流加载到FPGA 的内部存储器中，实现特定逻辑功能的过程。由于FPGA 电路的内部存储器都是基于RAM 工艺的，所以当FPGA电路电源掉电后， ...

可编程逻辑 XAPP503-针对Xilinx器件的SVF和XSVF文件格式
This application note provides users with a general understanding of the SVF and XSVF fileformats as they apply to Xilinx devices. Some familiarity with IEEE STD 1149.1 (JTAG) isassumed. For information on using Serial Vector Format (SVF) and Xilinx Serial Vector Format(XSVF) files in embedded pro ...
可编程逻辑 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 ci ...
可编程逻辑 基于CPLD的QDPSK调制解调电路设计
为了在CDMA系统中更好地应用QDPSK数字调制方式，在分析四相相对移相（QDPSK)信号调制解调原理的基础上，设计了一种QDPSK调制解调电路，它包括串并转换、差分编码、四相载波产生和选相、相干解调、差分译码和并串转换电路。在MAX+PLUSⅡ软件平台上，进行了编译和波形仿真。综合后下载到复杂可编程逻辑器件EPM7128SLC84-15中 ...
可编程逻辑 Virtex-5 GTP Transceiver Wizar
The LogiCORE™ GTP Wizard automates the task of creating HDL wrappers to configure the high-speed serial GTP transceivers in Virtex™-5 LXT and SXT devices. The menu-driven interface allows one or more GTP transceivers to be configured using pre-definedtemplates for popular industry standa ...
仿真技术 Multisim2001汉化破解版免费下载
这个软件需要你的本机操作的。其他机器是算不出来的！
就是说 一台电脑只有一个注册码对应！
这里有个办法：
MULTISIM2001安装方法：
一：运行SETUP.EXE安装。在安装时，要重新启动计算机一次。
二：启动后在“开始>程序”中找到STARTUP项，运行后，继续进行安装，安装过程中，第一次要求输入“CODE"码 ...
工控技术 工业系统安全问题和解决办法
Abstract: As industrial control systems (ICSs) have become increasingly connected and use more off-the-shelfcomponents, new vulnerabilities to cyber attacks have emerged. This tutorial looks at three types of ICSs:programmable logic controllers (PLCs), supervisory control and data acquisition (SCA ...
测试测量 XAPP713 -Virtex-4 RocketIO误码率测试器
 
The data plane of the reference design consists of a configurable multi-channel XBERT modulethat generates and checks high-speed serial data transmitted and received by the MGTs. Eachchannel in the XBERT module consists of two MGTs (MGTA and MGTB), which physicallyoccupy one MGT tile in t ...
电子元器件应用 陶瓷电容器的温度和电压的变化
Abstract: The reality of modern, small form-factor ceramic capacitors is a good reminder to always readthe data sheet. This tutorial explains how ceramic capacitor type designations, such as X7R and Y5V,imply nothing about voltage coefficients. Engineers must check the data to know, really know, h ...
