This Application Note covers the basics of how to use Verilog as applied to ComplexProgrammable Logic Devices. Various combinational logic circuit examples, such asmultiplexers, decoders, encoders, comparators and adders are provided. Synchronous logiccircuit examples, such as counters and state machines are also provided.

One of the most misunderstood constructs in the Verilog language is the nonblockingassignment. Even very experienced Verilog designers do not fully understand how nonblockingassignments are scheduled in an IEEE compliant Verilog simulator and do not understand whenand why nonblocking assignments should be used. This paper details how Verilog blocking andnonblocking assignments are scheduled, gives important coding guidelines to infer correctsynthesizable logic and details coding styles to avoid Verilog simulation race conditions

In this paper, we discuss efficient coding and design styles using verilog. This can beimmensely helpful for any digital designer initiating designs. Here, we address different problems rangingfrom RTL-Gate Level simulation mismatch to race conditions in writing behavioral models. All theseproblems are accompanied by an example to have a better idea, and these can be taken care off if thesecoding guidelines are followed. Discussion of all the techniques is beyond the scope of this paper, however,here we try to cover a few of them.

這個(gè)軟件需要你的本機(jī)操作的。其他機(jī)器是算不出來(lái)的! 就是說(shuō) 一臺(tái)電腦只有一個(gè)注冊(cè)碼對(duì)應(yīng)! 這里有個(gè)辦法: MULTISIM2001安裝方法: 一:運(yùn)行SETUP.EXE安裝。在安裝時(shí),要重新啟動(dòng)計(jì)算機(jī)一次。 二:?jiǎn)?dòng)后在“開(kāi)始>程序”中找到STARTUP項(xiàng),運(yùn)行后,繼續(xù)進(jìn)行安裝,安裝過(guò)程中,第一次要求輸入“CODE"碼時(shí), 輸入“PP-0411-48015-7464-32084"輸入后,會(huì)提示"VALID SERIAL NUMBER FOR MULTISIM 2001 POWER-PRO." 按確定,又會(huì)出現(xiàn)一個(gè)“feature code”框,輸入“FC-6424-04180-0044-13881”后, 在彈出的對(duì)話框中選擇“取消”,一路確定即可完成安裝。 三:1.運(yùn)行VERILOG目錄內(nèi)的SETUP安裝 2.運(yùn)行FPGA目錄內(nèi)的SETUP安裝 3.將CRACK目錄內(nèi)的LICMGR.DLL拷貝到WINDOWS系統(tǒng)的SYSTEM 目錄內(nèi) 4.并將VERILOG安裝目錄內(nèi)的同名文件刪除 5.將SILOS.LIC文件拷到VERILOG安裝目錄內(nèi)覆蓋原文件,并作如下編輯: 6.將“COMPUTER_NAME”替換為你的機(jī)器名 7.將“D:\MULTISIM\VERILOG\PATH_TO_SIMUCAD.EXE”替換為你的 實(shí)際安裝路徑。如此你便可以使用VERILOG了。 四:安裝之后,運(yùn)行MULTISIM2001,會(huì)要求輸入“RELEASE CODE",不用著急, 記下“SERIAL NUMBER"和“SIGNATURE NUMBER", 使用CRACK目錄內(nèi)的注冊(cè)器“MULTISIM KEYGEN.EXE" 將剛才記下的兩個(gè)號(hào)碼分別填入后, 即可得到"RELEASE CODE", 以后就可以正常使用了。 五:接下來(lái)運(yùn)行 database update目錄中的幾個(gè)文件, 進(jìn)行數(shù)據(jù)庫(kù)合并即可。祝你成功??! 六:?jiǎn)?dòng)MULTISIM2001時(shí)候的注冊(cè)碼 1: PP-0411-48015-7464-32084 2: 37506-86380 3:的三個(gè)空格 1975 2711 4842 里面包含了:Multisim2001漢化破解版、Multisim.V10.0.1.漢化破解版圖解 解壓密碼:www.pp51.com
