最新Cadence Allegro 16.6破解版，Windows 7下32位和64位，经实际测试，顺利运行，请仔细阅读安装说明。 后面附有高速百度网盘下载链接，压缩包中包括破解文件及安装说明，下面 Cadence16.6的版本个人感觉值得更新，有很多更新真心很实用很强大，但最重要的Display net names的功能的加入实在是感激涕零啊，因为当初从AD转到Cadence16.3时最不习惯的就是PCB上木有NET显示啊... 小弟win7安装时破解方法如下： 具体的步骤： 1、安装licensemanager，问license时，单击cancel，然后finish. 2、接下来安装cadence的product,即第二项,直到结束. 3、在任务管理器中确认一下是否有这两个进程,有就结束掉,即cdsNameServer.exe和cdsMsgServer.exe,没有就算了.(电脑开机没运行过Cadence软件就不用执行这一步). 5、把破解文件夹crack中LicenseManager文件夹下的pubkey、pubkey.exe和lLicenseManagerPubkey.bat放到Cadence\\LicenseManager目录下并运行lLicenseManagerPubkey.bat （如果是WIN764位操作系统请把cdslmd.exe文件复制到Cadence\\LicenseManager目录下覆盖原文件。其他操作系统不用，直接下一步） 6、把破解文件夹crack里crack\\SPB_16.6\\tools的pubkey、pubkey.exe和Tools.bat放到Cadence\\SPB_16.6\\tools目录下并运行Tools.bat （注意看一下DOS窗口会不会一闪而过，如果运行差不多一分钟就说明破解成功） 7、打开破解文件夹crack里LicGen文件夹,然后双击licgen.bat生成新的license.lic,习惯上把这license文件拷到桌面上放着. 8.在电脑开始菜单中的程序里找到cadence文件夹,点开再点开License Manager,运行License servers configuration Unilily,弹出的对话框中点browes...指向第7步拷贝到桌面上的license.lic,打开 它(open)再点下一步(next),将Host Name项中主机名改成你的电脑系统里的主机名（完整的计算机名称），然后点下一步按界面提示直到完成第7步. 9.在电脑开始菜单中的程序里找到cadence文件夹(windows7下),点开再点开,运行License client configuration Unility,填入5280@(你的主机名),点下一步(next),最后点finish,完成这第8步. 10.在电脑开始菜单中的程序里找到cadence文件夹(windows7下),点开再点开,运行Lm Tools,点Config Services项,Path to the license file项中,点Browes指向c:\\cadence\\License Manager\\license.dat(如果看不见icense.dat，请在类型中下拉选择DAT类型）,打开它 (open)再点Save Service.然后启动一下服务。到此,破解完成. 11、如果以上步骤都完成了，打开软件提示找不到证书，请打开环境变量，用户变量中看看 CDS_LIC_FILE 变量值是否为 5280@(你的主机名),如果没 CDS_LIC_FILE变量名，请添加一个变量。变量名为CDS_LIC_FILE 变量值为 5280@(你的主机名) 12. 64位操作系统，软件破解完请把cdslmd.exe文件复制到Cadence\\LicenseManager目录下覆盖原文件。 附我用的破解文件，希望给win7安装不成功的有点帮助

2013.6.25重新上传。文件rar压缩，容量2.19GB。 Cadence Allegro 16.5 crack 修正 破解 方法 支持 windows 7 具体的步骤： . 1、下载SPB16.5下来后，点setup.exe,先安装第一项licensemanager，问license时，单击cancel，然后finish. . 2、接下来安装cadence的product,即第二项,直到安装结束这个时间有点长装过以前版本的人都知道. . 3、在任务管理器中确认一下是否有这两个进程,有就结束掉,即cdsNameServer.exe和cdsMsgServer.exe,没有就算了. . 4.把安装目录下的SPB_16.5/tools/pspice目录下的orsimsetup.dll剪切出来找个地方先放着不理（待第8步完成后再拷回原来的地方,如果不用仿真部分删掉也无所谓）。 . 5、把pubkey、pubkey1.3.exe和lLicenseManagerPubkey.bat放到Cadence/LicenseManager目录下并运行 . lLicenseManagerPubkey.bat . 6、把破解文件夹crack里的pubkey、pubkey1.3.exe和ToolsPubkey.bat放到Cadence/SPB_16.5/tools目录下并运行 . ToolsPubkey.bat . 7、删除破解文件夹licens_gen下的license.lic,然后双击licgen.bat生成新的license.lic . 8.在电脑开始菜单中的程序里找到cadence文件夹(windows7下),点开 再点开License Manager,运行License servers . configuration Unilily,弹出的对话框中点browes...指向刚才生成的license.lic打开 它(open)再点下一步 . (next),将主机名改成你的电脑名称(系统里的主机名)后点下一步按界面提示直 . 到完成第7步. . 到此,破解完成. . 不必重启电脑就可运行程序(本人只在window7下装过) . 9、以上顺序不要搞反，直到第8便结束破解,无需重电脑就可以用了. . 以上根据rx-78gp02a写的改编.破解文件到他那去下载. . 以下两点仅供参考(完成上处8点后接着以下两条) . 1.在电脑开始菜单中的程序里找到cadence文件夹(windows7下),点开再点开,运行License client configuration Unility,不用填什么,点下一步(next),最后点finish,完成这第8步. . 2.在电脑开始菜单中的程序里找到cadence文件夹(windows7下),点开再点开,运行Lm Tools,点Config Services项,Path to the license file项中,点Browes指向c:/License Manager/license.lic,打开它 (open)再点Save Service. 到此,破解完成.不必重启电脑就可运行程序. 下面是分享的高速下载地址，经测试，带宽可以跑满！

Abstract: This application note describes a new generation of digital-input Class D audio amplifiers that achieve high PSRRperformance, comparable to traditional analog Class D amplifiers. More importantly, these digital-input Class D amplifiersprovide additional benefits of reduced power, complexity, noise, and system cost.

Abstract: Stuxnet, a sophisticated virus that damaged Iran's nuclear capability, should be an eye openerfor the world. We can choose to learn something very narrow (how to combat the Stuxnet virus) or wecan choose to focus on the larger goal of thwarting the next type of creative cyber attack. Unfortunately,critical industrial infrastructure is not currently designed with security as a key goal, leaving open multipleavenues for an educated and funded attacker to create massive problems. This tutorial outlines somebasic concepts that engineers and product definers should consider to make sure their new projects stayahead of future threats.

The LTC®4099 high effi ciency USB power manager andLi-Ion/Polymer battery charger seamlessly managespower distribution from multiple sources in portableapplications. It is differentiated from other USB powermanagers by its bidirectional I2C port that allows the hostmicroprocessor to control and monitor all aspects of theUSB power management and battery charging processes.In addition, a programmable interrupt generation functionalerts the host microprocessor to changes in device statusand provides unprecedented control of power managementfunctions. This high degree of confi gurability allowspost-layout changes in operation, even changes in thefi eld, and it allows a single qualifi ed device to be usedin a variety of products, thus reducing design time andeasing inventory management.

Occasionally, we are tasked with designing circuitry for aspecific purpose. The request may have customer originsor it may be an in-house requirement. Alternately, a circuitmay be developed because its possibility is simply tooattractive to ignore1. Over time, these circuits accumulate,encompassing a wide and useful body of proven capabilities.They also represent substantial effort. These considerationsmake publication an almost obligatory propositionand, as such, a group of circuits is presented here. This isnot the first time we have displayed such wares and, giventhe encouraging reader response, it will not be the last2.Eighteen circuits are included in this latest effort, roughlyarranged in the categories given in this publication’s title.They appear at the next paragraph.

The LTM8020, LTM8021, LTM8022 and LTM8023 μModule®regulators are complete easy-to-use encapsulated stepdownDC/DC regulators intended to take the pain and aggravationout of implementing a switching power supplyonto a system board. With a μModule regulator, you onlyneed an input cap, output cap and one or two resistorsto complete the design. As one might imagine, this highlevel of integration greatly simplifi es the task of printedcircuit board design, reducing the effort to four categories:component footprint generation, component placement,routing the nets, and thermal vias.
