Momwe mungapangire mabwalo a hardware okhala ndi zopotoka zochepa?

Pali zokumana nazo zambiri komanso chidziwitso chokhudza mabwalo amagetsi pa intaneti omwe ndi ochulukirapo.Monga kukhulupirika kwa chizindikiro, EMI, mapangidwe a PS adzakusokonezani.Osathamanga, tenga nthawi ndi chilichonse.
Nkhaniyi imaperekedwa kwa iwo omwe angoyamba kumene kapena akuyamba kupanga mabwalo a hardware, kuti muthe kutenga msewu wocheperako "opotoka" mu "hardware circuit design".

1. Malingaliro anthawi zonse

Kupanga mabwalo a hardware, chimango chachikulu ndi zomangamanga kuti muzindikire, koma kuchita izi sikophweka.Zina mwazinthu zazikuluzikulu zikhoza kukhala mabwana awo, aphunzitsi aganiza kale, ndizomwe zimakhazikitsidwa ndi lingaliro;komanso ena kuti adzipangire okha chimango, ndikofunikira kudziwa kuti ndi ntchito ziti zomwe mungakwaniritse, kenako ndikupeza ngati zitha kukwaniritsa ntchito zomwezo kapena zofananira za board board (kudziwa momwe mungagwiritsire ntchito zotsatira za ena momwe mungathere. , akatswiri odziwa zambiri adzadziwa momwe angaphunzire kuchokera ku zotsatira za ena).

2. Kumvetsetsa dera

Ngati mutapeza zojambulazo, ndiye zikomo, mutha kusunga nthawi yochuluka (kuphatikizapo kukonzanso ndi kukonzanso pambuyo pake).Koperani nthawi yomweyo?AYI, kapena kuwerenga ndikumvetsetsa koyamba, kumbali imodzi, kutha kuwongolera kumvetsetsa kwathu kwa dera, ndipo kumatha kupewa zolakwika pamapangidwe.

3. Simunapeze kalembedwe kake?

Choyamba, dziwani chip chachikulu cha IC, pezani deta, muwone ngati magawo ake ofunikira amakwaniritsa zofunikira zawo, zomwe ndizofunikira kwambiri zomwe amafunikira, komanso ngati atha kuwerenga magawo ofunikirawa, ndiye chifaniziro cha luso la injiniya wa Hardware, omwenso iyenera kuwunjikana pang'onopang'ono pakapita nthawi.Panthawi imeneyi, khalani bwino kufunsa mafunso, chifukwa zomwe simukuzimvetsa, ena nthawi zambiri amatha kukhala mawu oti akudzutseni, makamaka pakupanga ma hardware.

4. Zigawo zitatu zazikulu zopangira gawo la hardware

Schematic, PCB, bill of materials (BOM) tebulo.

Kupanga kwadongosolo ndikumasulira malingaliro am'mbuyomu kukhala schematic yozungulira.Zimafanana kwambiri ndi chithunzi cha dera lathu la mabuku.PCB imakhudza gulu lenileni la dera, lomwe limachokera pa chithunzi cha schematic mu netlist (netlist ndi mlatho pakati pa chithunzi cha schematic ndi PCB), ndi zigawo zina za phukusi zomwe zimayikidwa (mapangidwe) pa bolodi, ndiyeno malinga ndi mawaya owuluka (omwe amatchedwanso mawaya okoka kale) kuti alumikizane ndi ma siginecha ake amagetsi (wiring).Pambuyo pomaliza mawaya a PCB, zigawo zomwe ziyenera kugwiritsidwa ntchito ziyenera kufotokozedwa mwachidule, kotero tidzagwiritsa ntchito tebulo la BOM.

5. Ndi chida chotani chomwe mungagwiritse ntchito?

Prote, yomwe imadziwikanso kuti altimuml yosavuta kuyamba, yomwe imadziwikanso kwambiri ku China, kuthana ndi ntchito yonse yakhala yokwanira kuti wopanga agwiritse ntchito.

M'malo mwake, zilibe kanthu ndi protel yosavuta kapena zida zovuta za cadence, kapangidwe ka Hardware ndi kofanana (ntchito ya protel yofanana ndi windwos, ndi mtundu wa post-command; ndipo lingaliro la zinthu za cadence & allegro ndi mtundu wa pre-command, womwe umagwiritsidwa ntchito popanga, kusinthana mwadzidzidzi ku zida za cadence, kugwiritsa ntchito protel, kugwiritsa ntchito zida za cadence, kugwiritsa ntchito protel, kugwiritsa ntchito zida za cadence, kugwiritsa ntchito zida za cadence, kugwiritsa ntchito zida za cadence, kugwiritsa ntchito zida za cadence; Kugwiritsa ntchito zida za cadence Mwadzidzidzi sinthani ku zida za cadence, sizigwiritsidwa ntchito pazifukwa izi).
