Q01、如何使一条走线至两个不同位置零件的距离相同? 您可先在Design/Rule/High Speed/Matched Net Lengths的规则中来新增规则设定,最 后再用Tools/EqualizeNet Lengths 来等长化即可。 Q02、在SCHLIB中造一零件其PIN的属性,如何决定是Passive, Input, I/O, Hi- Z,Power,…..?在HELP中能找到说明吗?市面有关 SIM?PLD?的书吗?或贵公司有讲义? 你可在零件库自制零件时点选零件Pin脚,并在Electrical Type里,可以自行设定PIN的 属性,您可参考台科大的Protel sch 99se 里 面有介绍关于SIM的内容。 Q03、请问各位业界前辈,如何能顺利读取pcad8.6版的线路图,烦请告知 Protel 99SE只能读取P-CAD 2000的ASCII档案格式,所以你必须先将P-CAD8.6版的格式 转为P-CAD 2000的档案格式,才能让Protel读取。

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

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.

Abstract: Many modern industrial, medical, and commercial applications require temperature measurements in the extended temperature rangewith accuracies of ±0.3°C or better, performed with reasonable cost and often with low Power consumption. This article explains how platinumresistance temperature detectors (PRTDs) can perform measurements over wide temperature ranges of -200°C to +850°C, with absolute accuracyand repeatability better than ±0.3°C, when used with modern processors capable of resolving nonlinear mathematical equation quickly and costeffectively. This article is the second installment of a series on PRTDs. For the first installment, please read application note 4875, "High-Accuracy Temperature Measurements Call for Platinum Resistance Temperature Detectors (PRTDs) and Precision Delta-Sigma ADCs."

Modern electronic systems solve so many difficult problems that they often seem like magic. Nonetheless, these systems all have thesame basic limitation: they need a source of electrical Power! Most of the time this is a straightforward challenge for the electronicdesigner, because there are many Power-delivery solutions. Yet sometimes a device has no direct Power source, and running wiresor replacing batteries is impractical. Even when long-life batteries are usable, they eventually need to be replaced, which requires aservice call.

因为测量系统都用50欧姆, 如非特指, 以下所说的Gain均指功率增益(Power Gain). 但是一般的接收机的输入输出并非50欧姆, 因此有必要考虑电压增益(Voltage Gain).
