1 Tsim ntawm daim duab ntawm daim phiaj xwm txheej

Tus tsim ntawm daim qauv ntawm daim phiaj xwm txheej yog siv los kos ib daim duab ntawm daim phiaj xwm txheej ntawm daim duab ntawm Prote DXP los tsim qhov system. Lub feature yog tias qhov kos duab qhov tseeb yog siab, vim hais tias nws tsawg tshaj plaws ntawm kev kos yog ib tug mill inch. Nyob hauv txoj kev kos, ua kom tiav ntawm Protel DXP muaj ntau txoj kev los siv cov cuab yeej kos duab thiab ntau yam kev hloov kho, nrog rau cov cuab yeej kos duab nrog cov cuab yeej hlau thiab cov cuab yeej kos duab, yuav tsum them nqi rau qhov sib txawv ntawm lawv, tus tswv no tau kos ib txoj cai thiab qhov zoo ntawm daim phiaj xwm txheej zoo. Muaj ntau txoj hauv kev nkag mus rau lub caij, hauv cov tswv yim ntawm tus lej hauv lub Designator bar, tawm tswv yim ntawm cov khoom hauv feem ntawm "Tshooj Hom", thiab lub caij pob hom hauv Kab Nqa Nplua yuav tuaj yeem nkag mus ib ntus, vim nws tsis cuam tshuam rau qhov tsim ntawm daim duab ntawm daim phiaj xwm txheej. Tsis tas li ntawd, koj tuaj yeem nias qhov "qhov chaw" hauv tus thawj coj ntaus ntawv los tso lossis siv qhov chaw "qhov chaw" los tso ntau qhov khoom siv hluav taws xob.


Ua ntej, tso lub caij rau ntawm qhov schematic, nws yuav tsum tau xub muab tso rau hauv lub tsev qiv ntawv kev tivthaiv. Lub system muaj ntau yam ua ntej hauv lub tsev qiv ntawv, nws yog lub npe ntawm txoj kev ntawm programfile \ altium \ library \ Lwm yam Devices.intlib, vim hais tias Protel yog ib txoj kev txhim kho software rau kev tsim hluav taws xob ntawm cov neeg ua hauj lwm thiab feem ntau ntawm cov khoom siv hauv koos pis tawj, qhov chaw qiv ntawv muaj feem xyuam rau cov duab cim qhia ntau heev, muaj ntau qhov chaw ntawm qhov chaw qiv ntawv. Kuv tsis paub tus naj npawb ntau, yog li cov pib tshiab uas qhov chaw qiv ntawv yuav nrhiav tau qhov yuav tsum tau ua. Beginners feem ntau tsuas yog xav kom thauj tus "Lwm Yam Devices.lib", "Protel Dos.lib" ob feem ntawm cov tsev qiv ntawv, yeej txaus.


Qhov thib ob, kawm kom paub "lub cim cim npe" sib thooj rau qhov kev tivthaiv hauv phau ntawv no. Cov feem sib txawv ntawm cov cuab yeej feem ntau muaj nyob ntawm cov cim graphical cim qhia "Lwm Yam Devices.lib" uas yog muab los ntawm cov software, uas yog ntau dua intuitive thiab dlaim phaj. Qee lub ntsiab lus tseem ceeb tuaj yeem muab tso rau hauv lub hnab ntawv ntawm lawv tus kheej, yog li nws yooj yim dua los nrhiav cov khoom.


Thib peb, thaum peb sau cov schematic, peb yuav tsum xyuam xim rau txoj kev kos duab ntawm cov hlau. Qhov no yog qhov nws ua ob qho yuam kev. Ib qho yog siv kab (Kab) txhob siv traverse (Hlau). Qhov txawv ntawm lawv yog cov xim xim sib txawv, ib qho yog lub teeb xiav, ib qho yog xim dub. Lub ntsiab tseem ceeb yog tias txoj kab tsis muaj peev xwm ua tau hluav taws xob, thiab tus neeg xyuas pib tuaj yeem ua hluav taws xob, uas yog hluav taws xob qhov tseem ceeb. Lub taw tes pib thiab qhov kawg taw tes yuav tsum yog qhov chaw xaus thiab kev sib xyaw pins coincide, txawm los ntawm daim phiaj xwm txheej hauv lub voj voog uas tsis muaj qhov yuam kev, thiab qhov tseeb tom qab cov cai tswj xyuas hluav taws xob yuav tshwm sim rau hauv daim duab tso tawm ntawm qhov kev qhia tsis raug, tsis yog lawm.



2 Ua cov khoom

DCHP kuj yog qhov tseem ceeb hauv kev tsim cov khoom, peb nyob hauv cov txheej txheem, feem ntau ntsib tej teeb meem no, tsis yog kev tivthaiv txoj haujlwm POB feem ntau tsis tsimnyog lossis muab los ntawm lub tsev qiv ntawv tsim, ib daim duab hluav taws xob xws li daim duab daim duab ib puag ncig, tab sis qhov pib ntawm cov khoom siv feem ntau qhib thiab nquag kaw uas tsis muaj kev npaj txhij. Qhov no yuav tsum tau hais tias peb xub xub kos cov khoom hluav taws xob, thiab tom qab ntawd ces hauv daim duab.


Lub kaw lus muab ib qho kev tivthaiv loj los tivthaiv. Rau peb tuaj yeem ua qee yam khoom, tab sis nyob hauv tus txheej txheem ntawm cov khoom kos yog qhov yuav tsum tau mloog zoo rau qee qhov teeb meem, thawj yog cov txheej txheem thiab qauv daim duab ntawm cov pob khoom qiv ntawv tsis zoo ib yam, ntxiv rau txhua yam ntawm daim tawv nqaij, muaj ntau yam, tsis txhob tawm thaum kos duab. Qhov thib ob yog los kos cov khoom hluav taws xob, muaj peb hom, nrog 74LS00 ua piv txwv, tus qauv hom qub, hom Di Morgan hom De-Morgan thiab IEEE hom. Rau cov qauv peb, peb feem ntau siv cov qauv: Li qub, tab sis lwm tus ob yuav tsum tau kos thaum thaij duab teeb kos duab. 74LS00 yog lub rooj vag 4-2 NAND, nws muaj plaub yam khoom siv los txhuam tus naj npawb tus pin thiab kev hloov ntawm lub hwj chim thiab cov av hauv qab zais.


3 Generating network tables

Lub npav ntawm lub tsev kawm ntawv yog tus choj ntawm SCH thiab PCB. Yog hais tias tus thawj pib tsis muaj kev paub hauv daim duab vajtse hauv plab, nws yog ib qhov tsim nyog kom tau ib lub rooj sib tham ntawm lub schematic diagram ntawm Circuit Court. Nws yog tus plig ntawm lub rooj tsav tsheb tsis zoo no. Hauv tshooj lus no, koj yuav tsum kawm nyeem cov lus saum toj no. Lub rooj sib koom tes muaj ob ntu: qhov kev tivthaiv tshaj tawm thiab qhov kev txhais hauv nqe lus. Yuav ua li cas hloov lub encapsulation ntawm lub Cheebtsam hauv lub network rooj, qhov tivthaiv encapsulation nyob rau hauv txoj hauj lwm txawv nyob rau hauv lub rooj network, etc. Nws yog ib tug mob taub hau rau ntau tus neeg los xyuas qhov tseeb ntawm lub rooj network. Ib qho tseem ceeb yog vim tias lub npe ntawm cov npe hauv lub network tsis tuaj yeem nyeem ncaj qha rau ntawm daim phiaj duab schematic. Txoj kev los daws qhov teebmeem no yog los muab cov ntawv teev lus hauv lub network yooj yim rau txhua lub network ntawm daim duab qauv. Nws muaj ob lub homphiaj rau lub vas sab: ua ntej, ua rau lub npav lossis lwm lub network yoojyim pom; ua ntej, nthuav tawm qhov hluav taws xob kev txuas. Rau tib daim duab qauv, ib lub network nrog tib lub xov tooj ntawm tes hauj lwm qhia tau hais tias lawv txhua tus nrog ua ke.


4 Tsim ntawm pawg thawj coj saib xyuas

Tus tsim ntawm cov ntawv cog lus Circuit Court yog qhov tseem ceeb ntawm Protel DXP. Txuas ntxiv, yog hais tias ERC yog siv los ua PCB, kev soj ntsuam cov cai tswj hluav taws xob yuav tsum tau ua ua ntej ua PCB. Txwv tsis pub nws yuav ntxiv cov hauj lwm kho vaj tse hauv tsev kho mob, yuav tsum tau siv tes kos xim hlau, phaj tsim peb siv lub hwj chim Proth DXP ua kom muaj kev pom zoo ntawm lub rooj tsav xwm hauv circuit.


Protel software yog ib qho kev hlub los ntawm cov neeg nyiam ua electronic. Nws feem ntau pom tias yooj yim, tab sis qhov kev siv yooj yim thiab yooj yim yog kev lag luam ntawm nws tus kheej software, thiab kev paub txog PCB muab rau hauv nws yog qhov nyuaj rau cov neeg tshiab. Ntawm no, qhov ua kom pom tseeb ntawm kev qhia yog yuav ua li cas muab cov khoom tiv thaiv encapsulation, hloov mus rau lub rooj hauv lub network, thiab cia li tsim cov qauv PCB. Cov kauj ruam yog raws li nram qab no: tsim daim phiaj xwm txheej, npaj tswv yim ntawm lub rooj sib txig, qhov chaw tsis sib txuas, pib lub rooj sib tham, tsis siv neeg lub qhov rooj thiab kev hloov ntawm cov khoom, kev tswj cov cai thaiv, kev thaiv kev thiab kev hloov kho, daim ntawv tso tawm, txuag thiab luam tawm.
