最新Cadence Allegro 16.6破解版，Windows 7下32位和64位，經實際測試，順利運行，請仔細閱讀安裝說明。 后面附有高速百度網盤下載鏈接，壓縮包中包括破解文件及安裝說明，下面 Cadence16.6的版本個人感覺值得更新，有很多更新真心很實用很強大，但最重要的Display net names的功能的加入實在是感激涕零啊，因為當初從AD轉到Cadence16.3時最不習慣的就是PCB上木有NET顯示啊... 小弟win7安裝時破解方法如下： 具體的步驟： 1、安裝licensemanager，問license時，單擊cancel，然后finish. 2、接下來安裝cadence的product,即第二項,直到結束. 3、在任務管理器中確認一下是否有這兩個進程,有就結束掉,即cdsNameServer.exe和cdsMsgServer.exe,沒有就算了.(電腦開機沒運行過Cadence軟件就不用執行這一步). 5、把破解文件夾crack中LicenseManager文件夾下的pubkey、pubkey.exe和lLicenseManagerPubkey.bat放到Cadence\\LicenseManager目錄下并運行lLicenseManagerPubkey.bat （如果是WIN764位操作系統請把cdslmd.exe文件復制到Cadence\\LicenseManager目錄下覆蓋原文件。其他操作系統不用，直接下一步） 6、把破解文件夾crack里crack\\SPB_16.6\\tools的pubkey、pubkey.exe和Tools.bat放到Cadence\\SPB_16.6\\tools目錄下并運行Tools.bat （注意看一下DOS窗口會不會一閃而過，如果運行差不多一分鐘就說明破解成功） 7、打開破解文件夾crack里LicGen文件夾,然后雙擊licgen.bat生成新的license.lic,習慣上把這license文件拷到桌面上放著. 8.在電腦開始菜單中的程序里找到cadence文件夾,點開再點開License Manager,運行License servers configuration Unilily,彈出的對話框中點browes...指向第7步拷貝到桌面上的license.lic,打開 它(open)再點下一步(next),將Host Name項中主機名改成你的電腦系統里的主機名（完整的計算機名稱），然后點下一步按界面提示直到完成第7步. 9.在電腦開始菜單中的程序里找到cadence文件夾(windows7下),點開再點開,運行License client configuration Unility,填入5280@(你的主機名),點下一步(next),最后點finish,完成這第8步. 10.在電腦開始菜單中的程序里找到cadence文件夾(windows7下),點開再點開,運行Lm Tools,點Config Services項,Path to the license file項中,點Browes指向c:\\cadence\\License Manager\\license.dat(如果看不見icense.dat，請在類型中下拉選擇DAT類型）,打開它 (open)再點Save Service.然后啟動一下服務。到此,破解完成. 11、如果以上步驟都完成了，打開軟件提示找不到證書，請打開環境變量，用戶變量中看看 CDS_LIC_FILE 變量值是否為 5280@(你的主機名),如果沒 CDS_LIC_FILE變量名，請添加一個變量。變量名為CDS_LIC_FILE 變量值為 5280@(你的主機名) 12. 64位操作系統，軟件破解完請把cdslmd.exe文件復制到Cadence\\LicenseManager目錄下覆蓋原文件。 附我用的破解文件，希望給win7安裝不成功的有點幫助

2013.6.25重新上傳。文件rar壓縮，容量2.19GB。 Cadence Allegro 16.5 crack 修正 破解 方法 支持 windows 7 具體的步驟： . 1、下載SPB16.5下來后，點setup.exe,先安裝第一項licensemanager，問license時，單擊cancel，然后finish. . 2、接下來安裝cadence的product,即第二項,直到安裝結束這個時間有點長裝過以前版本的人都知道. . 3、在任務管理器中確認一下是否有這兩個進程,有就結束掉,即cdsNameServer.exe和cdsMsgServer.exe,沒有就算了. . 4.把安裝目錄下的SPB_16.5/tools/pspice目錄下的orsimsetup.dll剪切出來找個地方先放著不理（待第8步完成后再拷回原來的地方,如果不用仿真部分刪掉也無所謂）。 . 5、把pubkey、pubkey1.3.exe和lLicenseManagerPubkey.bat放到Cadence/LicenseManager目錄下并運行 . lLicenseManagerPubkey.bat . 6、把破解文件夾crack里的pubkey、pubkey1.3.exe和ToolsPubkey.bat放到Cadence/SPB_16.5/tools目錄下并運行 . ToolsPubkey.bat . 7、刪除破解文件夾licens_gen下的license.lic,然后雙擊licgen.bat生成新的license.lic . 8.在電腦開始菜單中的程序里找到cadence文件夾(windows7下),點開 再點開License Manager,運行License servers . configuration Unilily,彈出的對話框中點browes...指向剛才生成的license.lic打開 它(open)再點下一步 . (next),將主機名改成你的電腦名稱(系統里的主機名)后點下一步按界面提示直 . 到完成第7步. . 到此,破解完成. . 不必重啟電腦就可運行程序(本人只在window7下裝過) . 9、以上順序不要搞反，直到第8便結束破解,無需重電腦就可以用了. . 以上根據rx-78gp02a寫的改編.破解文件到他那去下載. . 以下兩點僅供參考(完成上處8點后接著以下兩條) . 1.在電腦開始菜單中的程序里找到cadence文件夾(windows7下),點開再點開,運行License client configuration Unility,不用填什么,點下一步(next),最后點finish,完成這第8步. . 2.在電腦開始菜單中的程序里找到cadence文件夾(windows7下),點開再點開,運行Lm Tools,點Config Services項,Path to the license file項中,點Browes指向c:/License Manager/license.lic,打開它 (open)再點Save Service. 到此,破解完成.不必重啟電腦就可運行程序. 下面是分享的高速下載地址，經測試，帶寬可以跑滿！

genesis9.0算號器提供genesis算號器使用視頻。安裝文件一定要放在小寫英文路徑下，中文不行，有大寫字母的英文也不行。1.算號器的只是算gnd的號，要算get的號，需要參考算號器的步驟。注意選擇破解有效時間。2.7天過期，30天過期，永不過期等。注意要用自己機器識別號去算，在get運行彈出來的序號對話框里，有機器識別號。3.安裝完成，啟動時，填寫進入用戶名和密碼時，一定不能用鼠標。直接用回車鍵，否則失效。密碼框內的密碼不可見，輸完直接回車，即可進入genesis界面。

Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synthesis tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptable. For example, if the circuit powers up in an invalid state, or the circuit is in an extreme working environment and a glitch sends it into an undesired state, the circuit may never get back to its normal operating condition.

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.

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.

As logic systems get larger and more complex, theirsupply current requirements continue to rise. Systemsrequiring 100A are fairly common. A high current powersupply to meet such requirements usually requires parallelingseveral power regulators to alleviate the thermalstress on the individual power components. A powersupply designer is left with the choice of how to drive theseparalleled regulators: brute-force single-phase or smartPolyPhaseTM.

The above title is not happenstance and was arrived at afterconsiderable deliberation. As a linear IC manufacturer, it isour goal to encourage users to design and build switchingregulators. A problem is that while everyone agrees thatworking switching regulators are a good thing, everyonealso agrees that they are difficult to get working. Switchingregulators, with their high efficiency and small size, areincreasingly desirable as overall package sizes shrink.Unfortunately, switching regulators are also one of themost difficult linear circuits to design. Mysterious modes,sudden, seemingly inexplicable failures, peculiar regulationcharacteristics and just plain explosions are commonoccurrences. Diodes conduct the wrong way. Things gethot that shouldn’t. Capacitors act like resistors, fusesdon’t blow and transistors do. The output is at ground, andthe ground terminal shows volts of noise.
