Tej Yam Ntawm Cov Kev Sau Ntaus Zauv

Jan 15, 2018

1. qhov muaj txiaj ntsim faib ntawm qhov chaw los ntawm tag nrho cov teeb meem

AX5318 yog CMOS lub laij lej, nrog rau plaub kev khiav haujlwm, siv sijhawm cia lub lag luam, puv puv npo, tsis siv zog-tawm, siv 1.5V roj teeb, thiab tsav ncaj qha tsav LCD. Tus neeg muas zaub xav tau muab luam tawm raws li cov khoom AX5315, vim AX5315 siv 3V fais fab mov, yog li nws yog qhov tsim nyog yuav tau nce Circuit voltage doubling hauv tus thawj AX5315. Raws li qhov tseem ntsiab ntawm AX5315 qhov kev tshawb fawb, pom tau ntawm daim duab kos ntawm cov thawj ntawm daim duab hauv qab ntawm sab xis, tab sis cov kev tawm tswv yim thiab cov zis feem ntau nyob rau sab qaum sab ntawm daim pheem thib, thiab qhov loj rau no random logic block A, zoo thiab kom nce qhov Circuit Court Circuit Court yeej zoo ib yam li; nyob rau tib lub sij hawm, daim tseem daim ntawv qhia nyob rau hauv cov kev taw qhia ntawm kev twb kev txuas yog ntau dua, meej dua txog kev taw qhia ntawm kev twb kev txuas, yog li nws yuav tsum tau ua raws li qhov teeb tsa ntawm daim duab 1, thawj random block logic A tsiv nrog zoo sib xws doubling Circuit; thiab lub nruas logic block A shaping ua rau kev nyias nyias, mus rau hauv thaj tsam ntawm thaj av kom void cov compressed. Qhov no ua rau kev txuas ntawm daim duab tseem ceeb dua qub, thiab nws ua rau siv qhov chaw zoo. Raws li lub tswv yim no, thaj tsam ntawm qhov tsim tawm yog txo 12.1%, thiab lub hom phiaj yog 8% ntawm qhov yuav tsum tau ua kom tiav.

2. Ua ntej nrhiav lub hwj huam kab thiab hauv av hlau thiab ces maj mam

Feem ntau hais lus, kev ua haujlwm ntawm kev tsim qhov kev teeb tsa yog ua los ntawm ntau tus neeg. Tom qab txiav txim siab txog qhov kev npaj layout, tag nrho qhov teeb meem faib rau ntau qhov chaw, thiab qhov kawg zaum kawg yog aggregated. Yog hais tias tsis muaj cov fais fab thiab cov xaim hauv av, tsis tag nrho cov kev sib txuas raug kho zoo ib yam, thiab qhov kev ua haujlwm ntawm tus nti yuav raug cuam tshuam. Ua ntej, vim hais tias tam sim no ntws los ntawm lub fais fab kab thiab lub hauv paus xaim yog loj, nws yuav tsum tau coarsely kos tshaj li lub dav hluav taws xob kab. Qhov thib ob, txoj kab hluav taws xob sib txuas tuaj yeem txuas nrog POLY, thaum lub fais fab kab thiab cov xaim hauv av tsuas txuas tau los ntawm cov hlau, thiab kev sib txuas lus tsis zoo hauv POLY. Yog tias cov kev hloov pauv nyob rau hauv qhov xaus, nws yog qhov nyuaj heev los siv tsawg dua qhov chaw. Yog li, ua ntej compression, peb yuav tsum xub paub meej tias lub hwj huam kab thiab hauv av kab, thiab yuav tsis coj ntau yam kev lag luam, thiab muaj peev xwm ua tiav ob zaug nrog ib nrab ntawm kev siv zog.


3. DRC cov kev cai yuav tsum sau kom zoo

Txoj cai DRC yog ib txoj cai uas siv los xyuas seb qhov layout ntawm cov ntaub ntawv teeb tsa puas ua tau raws li qhov yuav tsum tau ua ntawm txoj haujlwm. Sau cov cai DRC tsis yog los ua kom tau raws li cov kev xav tau, tab sis kuj yuav tsum tau lees paub cov kev ua yuam kev uas tau ua nyob hauv kev kos duab. Txoj cai DRC zoo tuaj yeem tshawb xyuas txhua yam ntawm cov lus yuam kev hauv cov qauv tsim daim ntawv qhia, thiab tsim qhov tsim teeb tsa kev txhim kho thiab txhim khu kev qha. DRC cov cai yuav tsum tau muab sau tseg.


1) hais kom meej meej txhua lub ntsiab lus ntawm DRC cov ntaub ntawv, tshwj xeeb tshaj yog rau cov cuab yeej sib txawv, tib qhov kev txiav txim ntawm cov lus txib yuav txawv, thiab tus naj npawb kuj yuav txawv. Piv txwv, hauv DRACULAR, peb yuav tsum tau xyuas qhov kis ntawm POLY cov khaubncaws sab nraud povtseg hauv lub EXT. Peb tsuas yog xav tau ib qho EXT hais kom ua, xws li Formula 1, thaum nyob hauv DIVA, peb xav tau SEP thiab TSIS TXHOB ob nqe lus kom ua tiav tib lub hom phiaj, xws li formula (2).

Nyob rau hauv daim ntawv (2), SEP siv los xyuas qhov ntxaiv raws li qhia hauv daim duab 2, thiab TSIS TXHOB siv los xyuas qhov ntxaiv raws li qhia hauv daim duab 3. Rau daim duab 4, nws yog qhov kos tau ntawm qhov sib txawv ntawm cov khaubncaws sab nraud povtseg ntawm cov duab ( POLY thiab hlau) nrog tsuas yog ib tus SEP hais kom ua. Yog hais tias koj tsis ua tib zoo to taub qhov kev siv ntawm txhua qhov hais kom ua, nws yooj yim ua yuam kev thiab ua rau lub txim loj ntawm qhov yuam kev ntawm qhov tsim. Muab piv nrog ob yam cuab yeej ntawm DRACULAR thiab DIVA, DRACULA cov lus txib muaj ntau yam kev cai, thiab cov lus txib sau tau yooj yim thiab universality. Nws raug nquahu kom siv nws ua qhov cuab yeej nyiam los sau cov cai DRC.

2) cov cai tswj kom ua tau raws li cov txheej txheem ntawm txoj haujlwm yuav tsum ua tib zoo sau, thiab qee qhov yuam kev uas yuav yooj yim rau hauv qhov tsim ntawm qhov tsim, xws li (tag nrho hauv daim ntawv DIVA), yuav tsum raug xam tias yog.

Hauv ib lo lus, nws tsis yog ib qho yooj yim uas yuav sau tau cov ntaub ntawv zoo DRC. Nws xav tau kev paub txog cov txheej txheem thiab kev txuam ntawm kev paub.


4. Kev Ntsuam Xyuas LVL

Vim hais tias lub compression ntawm qhov layout nce lub Circuit Court Circuit Court Circuit, yog li nws tuaj yeem tsis yooj yim xyuas qhov layout ntawm AX5315 nrog LVL. Nyob rau tib lub sijhawm, vim hais tias lub nti muaj ROM cheeb tsam, nws kos tsis tau schemas thiab ua LVS kev soj ntsuam, yog li AX5318 qhov tseeb qhov teeb meem yog qhov nyuaj. Tom qab kev sib tham ntawm ntau txoj kev, thaum kawg siv cov qauv nram qab no, ua ntej, ntxiv ib qho hluav taws xob qhov sib npaug ntawm qhov kev soj ntsuam LVS, los xyuas qhov tseeb; ces tsis muaj cov ntaub ntawv nyob rau hauv lub AX5315 sau, thiab ces txhais tau ib co tshiab kev twb kev txuas txheej thiab qhov txuas qhov, qhov input thiab output voltage doubling Circuit Court txuas mus rau qhov chaw nyob rau hauv AX5315. Qhov no ua rau kev siv qhov kev tsim tawm rau LVL check. Vim hais tias tus thawj AX5315 layout yeej muaj tseeb, thiab qhov teeb meem ntawm qhov sib tw ntawm qhov hluav taws xob tau yog LVS kos, yog tias qhov yuam kev tsuas yog muaj peev xwm nyob rau hauv ntau qhov hluav taws xob, qhov chaw nres nkoj qhov kev tso zis ntawm txoj kab, qhov yuam kev tau raug txo kom tsawg; nyob rau tib lub sij hawm siv cov ntaub ntawv sib txawv los ntawm ntau tus neeg mus rau qhov yuav tshwm tau ntawm xws li tus neeg tsim kev sib txawv ua qhov yuam kev ib yam tsawg dua. Lub tswv yim ntawm kev ua ntawm lub tswv yim ntawm hom ua pov thawj no yog raws li nram no:


Txhais cov txheej tshiab:

LVL -CUT

Lub ntsuas txheej siv rau kev ntsuam xyuas LVL, siv los txiav tawm cov ntaub ntawv uas tsis tsim nyog

LVL -ROUT

Kev sib txuas txheej siv rau kev ntsuam xyuas LVL, siv rau kev sib txuas sib txuas

LVL -CON

LVL kuaj cov txheej txheem pore rau kev sib txuas ntawm LVL-ROUT txheej thiab AX5315 cov ntaub ntawv, thiab qhia txog peb cov txheej ntawm qhov kev txuas (DRACULAR hom) hauv cov ntaub ntawv LVL:

Los ntawm LVL-CON kev sib txuas ntawm LVL-ROUT thiab METAL, POLY, NDIFF, PDIFF txheej yog pom nyob hauv qhov tsim, raws li qhia hauv daim duab 5
