Q1: Ingabe ukuphepha okusebenzayo kuqala ngomklamo?
I-A1: Ukunemba, uma kudingekile ukuthobela imikhiqizo ye-ISO 26262, imisebenzi efanele yokuphepha kufanele ihlelwe ekuqaleni kwephrojekthi, kufanele kwakhiwe uhlelo lokuphepha, futhi ukuqaliswa kwemisebenzi yokuphepha ngaphakathi kohlelo kufanele kuthuthukiswe ngokuqhubekayo. ngokusekelwe ekuphathweni kwekhwalithi kuze kube yilapho yonke imisebenzi yokuklama, ukuthuthukiswa kanye nokuqinisekisa isiqediwe futhi kwakhiwa ifayela lokuphepha.Ngesikhathi sokubuyekezwa kokugunyazwa, ukucwaninga kokuphepha okusebenzayo ukuze kuqinisekiswe ukufaneleka kwemikhiqizo esemqoka yomsebenzi kanye nokuhambisana nenqubo, futhi ekugcineni kudingeka kufakazele izinga lokuthobelana komkhiqizo ne-ISO 26262 ngokuhlolwa kokusebenza kokuphepha.Ngakho-ke, i-ISO 26262 ihlanganisa imisebenzi yokuphepha yomjikelezo wempilo ogcwele wemikhiqizo ehlobene nokuphepha ye-elekthronikhi/kagesi.
Q2: Ithini inqubo yesitifiketi sokuphepha esisebenzayo sama-chips?
A2: Ngokuya nge-ISO 26262-10 9.2.3, singakwazi ukwazi ukuthi i-chip isebenza njengengxenye yezokuphepha ngaphandle komongo (SEooC), futhi inqubo yayo yokuthuthukisa ngokuvamile ihilela izingxenye 2,4(izingxenye)5,8,9, uma ukuthuthukiswa kwesofthiwe kanye nokukhiqizwa akubhekwa.
Uma kukhulunywa ngenqubo yesitifiketi, idinga ukunqunywa ngokuya ngemithetho yokusetshenziswa kwesitifiketi yenhlangano ngayinye enikeza izitifiketi.Ngokuvamile, kuyo yonke inqubo yokuthuthukisa ama-chip, kuzoba khona izindawo zokucwaninga ezi-2 kuya kwezi-3, njengokucwaninga kwesigaba sokuhlela, ukucwaningwa kwamabhuku esiteji sokuklama nokuthuthukiswa, kanye nokuhlolwa kwesigaba sokuhlola nokuqinisekisa.
Q3: Ikhabethe elihlakaniphile likusiphi isigaba?
A3: Ngokuvamile, uhlelo oluhlobene nokuphepha lwe-elekthronikhi/ lukagesi oluzungeze ikhabethe elihlakaniphile luyi-ASIL B noma ngezansi, oludinga ukuhlaziywa ngokuya ngokusetshenziswa kwangempela komkhiqizo wangempela, futhi izinga elinembile le-ASIL lingatholwa nge-HARA, noma Izinga le-ASIL lomkhiqizo linganqunywa ngokunikezwa kwesidingo se-FSR.
Q4: Ku-ISO 26262, iyiphi iyunithi encane edinga ukuhlolwa?Isibonelo, uma siyidivayisi yamandla, ingabe kudingeka futhi senze ukuhlola nokuqinisekisa kwe-ISO 26262 lapho senza amaleveli egeji yemoto?
I-A4: ISO 26262-8:2018 13.4.1.1 (Isahluko sokuhlola izakhi ze-Hardware) izohlukanisa i-Hardware ibe izinhlobo ezintathu zezinto, uhlobo lokuqala lwezingxenye ze-Hardware ngokuyinhloko ziyizingxenye ezihlukene, izingxenye ze-passive, njll. Akudingi ukucabangela i-ISO 26262 , kudingeka kuphela ukuthobela imithetho yemoto (njenge-AEC-Q).Endabeni yohlobo lwesibili lwezinto (izinzwa lokushisa, ama-ADC alula, njll.), kuyadingeka ukuthi kubhekwe ukuba khona kwezindlela zokuphepha zangaphakathi ezihlobene nomqondo wokuphepha ukuze kunqunywe ukuthi ingabe idinga ukucatshangelwa ukuze kuthotshelwe i-ISO 26262 ;Uma kuyisici seSigaba 3 (MCU, SOC, ASIC, njll.), kuyadingeka ukuthi sithobelane ne-ISO 26262.
Ukusebenza kwe-GRGTEST kwamandla wesevisi yokuphepha
Ngokuhlangenwe nakho okucebile kwezobuchwepheshe kanye namacala aphumelelayo ekuhlolweni kwemikhiqizo yezimoto nesistimu yezitimela, singahlinzeka ngezinsiza eziphelele zokuhlola nezitifiketi zawo wonke umshini, izingxenye, i-semiconductor kanye nezinto zokusetshenziswa ze-Oems, abahlinzeki bezingxenye kanye namabhizinisi e-chip design ukuqinisekisa ukwethembeka, ukutholakala. , ukugcinwa nokuphepha kwemikhiqizo.
sinethimba lokuphepha elisebenza ngobuchwepheshe obuthuthukile, eligxile ekuvikelekeni okusebenzayo (okuhlanganisa izimboni, ujantshi, izimoto, isekethe edidiyelwe kanye neminye imikhakha), ukuphepha kolwazi kanye nochwepheshe bokuphepha obusebenzayo abalindelekile, abanolwazi olucebile ekusetshenzisweni kwesekethe ehlanganisiwe, ingxenye kanye nokusebenza kukonke. ukuphepha.Singahlinzeka ngezinsizakalo zokuma okukodwa zokuqeqesha, ukuhlolwa, ukucwaninga kwamabhuku kanye nezitifiketi kumakhasimende ezimboni ezahlukene ngokuya ngamazinga okuphepha embonini ehambisanayo.
