This application note contains a reference design consisting of HDL IP and Xilinx AdvancedConfiguration Environment (ACE) software utilities that give designers great flexibility increating in-system programming (ISP) solutions. In-system programming support allowsdesigners to revise existing designs, package the new bitstream programming files with theprovided software utilities, and update the remote system through the JTAG interface using theEmbedded JTAG ACE Player.

The Virtex™-4 user access register (USR_ACCESS_VIRTEX4) is a 32-bit register thatprovides direct access to bitstream data by the FPGA fabric. It is useful for loadingPowerPC™ 405 (PPC405) processor caches and/or other data into the FPGA after the FPGAhas been configured, thus achieving partial reconfiguration. The USR_ACCESS_VIRTEX4register is programmed through the bitstream with a command that writes a series of 32-bitwords.

Integrated EMI/Thermal Design forSwitching Power SuppliesWei ZhangThesis submitted to the Faculty of theVirginia Polytechnic Institute and State Universityin partial fulfillment of the requirements for the degree of Integrated EMI/Thermal Design forSwitching Power SuppliesWei Zhang(ABSTRACT)This work presents the modeling and analysis of EMI and thermal performancefor switch power supply by using the CAD tools. The methodology and design guidelinesare developed.By using a boost PFC circuit as an example, an equivalent circuit model is builtfor EMI noise prediction and analysis. The parasitic elements of circuit layout andcomponents are extracted analytically or by using CAD tools. Based on the model, circuitlayout and magnetic component design are modified to minimize circuit EMI. EMI filtercan be designed at an early stage without prototype implementation.In the second part, thermal analyses are conducted for the circuit by using thesoftware Flotherm, which includes the mechanism of conduction, convection andradiation. Thermal models are built for the components. Thermal performance of thecircuit and the temperature profile of components are predicted. Improved thermalmanagement and winding arrangement are investigated to reduce temperature.In the third part, several circuit layouts and inductor design examples are checkedfrom both the EMI and thermal point of view. Insightful information is obtained.

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"码时， 输入“PP-0411-48015-7464-32084"输入后，会提示"VALID SERIAL NUMBER FOR MULTISIM 2001 POWER-PRO." 按确定，又会出现一个“feature code”框，输入“FC-6424-04180-0044-13881”后， 在弹出的对话框中选择“取消”，一路确定即可完成安装。 三：1.运行VERILOG目录内的SETUP安装 2.运行FPGA目录内的SETUP安装 3.将CRACK目录内的LICMGR.DLL拷贝到WINDOWS系统的SYSTEM 目录内 4.并将VERILOG安装目录内的同名文件删除 5.将SILOS.LIC文件拷到VERILOG安装目录内覆盖原文件，并作如下编辑： 6.将“COMPUTER_NAME”替换为你的机器名 7.将“D:\MULTISIM\VERILOG\PATH_TO_SIMUCAD.EXE”替换为你的 实际安装路径。如此你便可以使用VERILOG了。 四：安装之后，运行MULTISIM2001,会要求输入“RELEASE CODE",不用着急， 记下“SERIAL NUMBER"和“SIGNATURE NUMBER", 使用CRACK目录内的注册器“MULTISIM KEYGEN.EXE" 将刚才记下的两个号码分别填入后， 即可得到"RELEASE CODE", 以后就可以正常使用了。 五：接下来运行 database update目录中的几个文件， 进行数据库合并即可。祝你成功！！ 六：启动MULTISIM2001时候的注册码 1： PP-0411-48015-7464-32084 2： 37506-86380 3:的三个空格 1975 2711 4842 里面包含了：Multisim2001汉化破解版、Multisim.V10.0.1.汉化破解版图解 解压密码：www.pp51.com

Town是一个100% 纯Java API，它位于JDBC API的顶部。这个API的目的是简化和一个JDBC兼容的关系数据库的交互。通过使用Town,可以执行和管理select/insert/update/delete SQL语句，而不用真正写一行SQL。Town也可以使用任何JDBC连接字符串和内部连接池。

sheerdns is a master DNS server whose zone records are stored on a One-Record-Per-File bases. Because of this, it is the simplest of any DNS to configure, the easiest to update, and the most efficient for networks that experience a lot of updates (for example master servers for dynamic IP address ranges). You never have to restart it; any updates are available immediately without having to notify the sheerdns process. 来源: http://freshmeat.net/projects/sheerdns/?topic_id=149 sheerdns是一个主DNS服务器，它的域记录保存在一个One-Record-Per-File（每文件一个记录）的库中。因此，它是最简单的DNS配制，最容易更新，对于有大量更新的网络（如动态IP地址范围的主服务器）来说它是最高效的。你不必重新启动它，任何更新不用通知对应DNS进程就可以立即生效。

使用 Http 在线自动升级程序: 近几日一些程序老要修改点小毛病，为避免每次都通知程序使用者，便有想做一个在线自动升级的程序。在VCKBase看到一个是使用 FTP 的，想到 FTP 需要用户名密码，许多程序如KFW 防火墙都能监看到程序发送的数据包，为防止密码泄露，故自己选用Http来做更新。我的思路是用命令行传递程序名称、版本号和 Update.ini 配置文件的 URL。
