Uyila njani iisekethe zehardware ezinojiko olumbalwa?

Kukho amava amaninzi kunye nolwazi malunga neesekethe ze-hardware kwi-Intanethi ezothusayo.Njengomqondiso wengqibelelo, i-EMI, uyilo lwe-PS luya kukubhidanisa.Musa ukungxama, thatha ixesha lakho ngayo yonke into.
Eli nqaku linikezelwe kwabo baqalayo okanye malunga nokuqalisa ukuyila iisekethe ze-hardware, ukuze ukwazi ukuthatha indlela encinci "i-detours" kwi "designer circuit circuit".

1. Iingcamango ngokubanzi

Ukuyila iisekethe zehardware, isakhelo esikhulu kunye noyilo loyilo, kodwa ukwenza oku akulula ngenene.Ezinye zesakhelo esikhulu sinokuba ngabaphathi babo, ootitshala sele becingile, bakuphela kokuphunyezwa kombono othile;kodwa kwakhona abanye ukuyila esabo isakhelo, kuyimfuneko ukufumanisa ukuba yeyiphi imisebenzi ekufuneka iphunyezwe, kwaye emva koko ufumanise ukuba kukho ukuphumeza imisebenzi efanayo okanye efanayo yebhodi yereferensi (ukwazi ukusebenzisa iziphumo zabanye kangangoko kunokwenzeka. , iinjineli ezinamava ziya kuyazi indlela yokufunda kwiziphumo zabanye).

2. Qonda isekethe

Ukuba ufumana i-design yereferensi, ngoko ke uvuyisana naye, ungagcina ixesha elininzi (kubandakanya ukuyila kwangaphambili kunye ne-post-debugging).Khuphela ngoko nangoko?HAYI, okanye ufunde kwaye uqonde kuqala, kwelinye icala, unokuphucula ukuqonda kwethu isiphaluka, kwaye unokuphepha iimpazamo kuyilo.

3. Awufumananga uyilo lwereferensi?

Okokuqala misela i-chip enkulu ye-IC, fumana idatha yedatha, ubone ukuba iiparameters zayo eziphambili ziyahlangabezana neemfuno zazo, eziziiparamitha eziphambili ezizidingayo, kwaye ingaba ziyakwazi ukufunda ezi parameters eziphambili, ziyimbonakaliso yesakhono senjineli ye-hardware, nayo. kufuneka ziqokelelwe kancinci ngokuhamba kwexesha.Ngeli xesha, yiba kakuhle ukubuza imibuzo, kuba into ongayiqondiyo, abanye banokuba lilizwi lokukuvusa, ngakumbi kuyilo lwehardware.

4. Iinxalenye ezintathu eziphambili zoyilo zesekethe ye-hardware

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

Uyilo lweSchematic kukuguqulela iingcamango zangaphambili kwi-circuit schematic.Ifana kakhulu nomzobo wesiphaluka seencwadi zethu.I-PCB ibandakanya ibhodi yesekethe yokwenyani, esekwe kwidayagram ecwangcisiweyo ibe kuluhlu lomnatha (uluhlu lomnatha yibhulorho phakathi komzobo wesicwangciso kunye nePCB), kunye namacandelo athile ephakheji ebekwe (uyilo) ebhodini, kwaye ngoko iingcingo eziphaphazelayo (ezikwabizwa ngokuba ziingcingo ezitsalwe ngaphambili) ukudibanisa imiqondiso yayo yombane (iingcingo).Emva kokugqitywa kocingo lwe-PCB lobeko, ngawaphi amacandelo aza kusetyenziswa kufuneka ashwankathelwe, ngoko siya kusebenzisa itafile ye-BOM.

5. Sesiphi isixhobo osisebenzisayo?

Prote, eyaziwa ngokuba altimuml lula ukuqalisa, kwakhona ethandwa kakhulu e-China, ukuhlangabezana nomsebenzi jikelele iye yanele ukuba ekuqaleni umyili ukusebenzisa.

Ngapha koko, akukhathaliseki nokuba uneprotel okanye izixhobo ezintsonkothileyo ze-cadence, uyilo lwe-hardware luyafana (umsebenzi weprotel ufana ne-windwos, luhlobo lwe-post-command; kunye ne-cadence product concept & allegro luhlobo lomyalelo wangaphambili, osetyenziswa kwi-protel, tshintshela ngokukhawuleza izixhobo ze-cadence, ukusetyenziswa kwe-protel, kunye nokusetyenziswa kwezixhobo ze-cadence, ukusetyenziswa kwe-protel, ukusetyenziswa kwezixhobo ze-cadence, ukusetyenziswa kwe-cadence, ukusetyenziswa kwezixhobo ze-cadence, ukusetyenziswa kwezixhobo ze-cadence, ukusetyenziswa kwezixhobo ze-cadence; Ukusetyenziswa kwezixhobo ze-cadence.Ngequbuliso tshintshela kwizixhobo ze-cadence, aziyi kusetyenziselwa esi sizathu).
