1. Kev npaj tsim tawm qauv IC

Ua kom tiav cov kev cai ntawm Circuit Court, tsim teeb tsa hauv kev teeb tsa kev tsim kho, tsim teeb tsa tsim ntawm EDA cov cuab yeej tsim tawm los ntawm lub platform, yuav tsum vam khom cov tshuab, uas qhia cov kev cai tsim qauv tsim hauv cov chaw tsim khoom, ua cov haujlwm nram qab no:

①Mastering kev siv qhov kev teeb tsa editing module thiab qhov tseeb qhov tseeb qhov tseeb cuab tam hauv lub CDA hnub 9 hnub. Daim duab 1 qhia txog tus txheej txheem ntawm kev tsim cov qauv tsim nyob rau hauv ZeniLE ib puag ncig. Qhov txheej txheem qhov kev paub meej txog ZineVERI yog muaj nyob rau hauv Xam 2.

②Ntawm thiab to taub cov cai tsim qauv tsim. Cov cai tswj tsim rau cov khoom siv hluav taws xob hauv geometry hauv kev tsim ntawm cov kev cai tsim nyog thiab tuaj yeem hu tau, cov cai no yog ib qho kev sib cog lus nruab nrab ntawm cov neeg tsim qauv thiab cov txheej txheem engineers los tiv thaiv lwm tus neeg txhais tau tias, kev cai tsim cov qauv tsim los ua tus qauv tsim, thiab siv cov cai no hauv qhov zoo tshaj plaws tawm los thiab xyuas kom muaj kev cia siab ntawm qhov Circuit Court nyob rau hauv qhov chaw uas tsim qhov qis tshaj qhov tsim nyog kom ntau li ntau tau.

③Cov ntaub ntawv ua pov thawj cov ntaub ntawv hais kom ua (cov ntaub ntawv hais kom ua) tsim. Kev tsim daim ntawv tso cai yuav tsum tau plaub cov ntaub ntawv (DRC, ERC, NE, thiab LVS) los txhawb, thiab cuaj hnub EDA qhov system txhawb Dracula daim ntawv ntawm cov ntaub ntawv hais kom ua.

④Yog ib qho kev pabcuam thij ib nrab siv los tsim teebmeem, ib lub tsev qiv ntawv tsim muaj qhov siab ntawm qhov kev ua haujlwm hauv tsev ib ntus uas tsim nyog los txhawb nws. Cov koog no muaj peev xwm sib txawv ntawm cov rooj vag circuits, los yog ntxeev flops, puv zom zaws, sau npe thiab lwm yam kev ua haujlwm zoo. Peb tuaj yeem txhim kho lub tsev qiv ntawv ntawm daim duab raws li thawj peb txoj kev npaj. Qhov kev sib tw semi customization yuav piv tau cov qauv siv thiab txo cov qauv tsim.

2. Layout design of IC layout

Tam sim no, cuaj hnub, EDA qhov system tsis tuaj yeem tsim teeb tsa cia, thiab phau ntawv tsim qauv tsim nyog rau hauv qhov tsim kho tshiab ntawm ZENLE. Qhov teeb tsa ntawm qhov kev teeb tsa ntawm qhov kev teeb tsa muaj xws li kev teeb tsa, chav tsev configuration thiab thaiv. Feem ntau, qhov tsim layout yuav tsum tsim nyog, chav teeb raug kho kom haum thiab qhov thaiv yog tsim nyog.

2.1 Qhov tsim yuav tsum tsim nyog

Lub tswv yim ntawm qhov kev teeb tsa ntawm qhov kev teeb tsa ntawm lub nruab nrab ntawm kev sib koom tes yog hais txog lub tswv yim ntawm kev sib tw thiab ICout layout log IC yog tsim los ntawm txawv network register, adder thiab tswj logic Circuit Court, tus chip tau muab faib ua ntau lub cheeb tsam me me, cov tswv yim tshiab ntawm cov khoom nyob hauv txhua cheeb tsam. Muaj qee cov ntsiab lus los soj ntsuam cov rationality ntawm qhov layout yog:

①Yog qhov kev faib tawm ntawm qhov kawg tau siv los yog muaj feem sib luag nrog cov sib luag; txawm tias nws yog nyob rau hauv txoj kab nrog cov kev cai ntawm cov txheej txheem ntawm lub plhaub thiab lub plhaub.

②Cov chav tsev uas muaj kev tshwj xeeb (piv txwv, sim zoo ib yam, sib thooj los yog nyob deb) yog tsim nyog. Piv txwv, hauv qhov teeb meem ntawm CMOS Circuit Court, peb yuav tsum sim ua kom thaj chaw N ntawm N zoo thiab N tub kom deb ntawm kev sib txuas kom txo tau tus nqi ntawm beta NPN, uas yog qhov tseem ceeb tshaj rau cov theem tawm.

③ Yog tias qhov layout yog compact, thiaj li maximize qhov ceev ntawm lub pob, peb xav kom tag nrho nti los ua square ntau li ntau tau.

④ Qhov kub cev yuav tsum tsim nyog. Lub tshuab cua sov feem ntau yuav tsum tau muab tso rau hauv qhov chaw ntawm lub nti.
