I-Q&A ye-ISO 26262 (Icandelo Ⅲ)

I-Q9: Ukuba i-chip idlula i-ISO 26262, kodwa isahluleka ngexesha lokusetyenziswa, ngaba unokunika ingxelo yokungaphumeleli, efana nengxelo ye-8D yemigaqo yesithuthi?
A9: Akukho budlelwane obuyimfuneko phakathi kokungaphumeleli kwe-chip kunye nokungaphumeleli kwe-ISO 26262, kwaye kukho izizathu ezininzi zokungaphumeleli kwe-chip, enokuthi ibe ngaphakathi okanye ngaphandle.Ukuba isiganeko sokhuseleko sibangelwa ukungaphumeleli kwe-chip kwinkqubo ehambelana nokhuseleko ngexesha lokusetyenziswa, ihambelana no-26262. Okwangoku, kukho iqela lokuhlalutya lokungaphumeleli, elinokunceda abathengi bafumane isizathu sokungaphumeleli kwe-chip. kwaye ungaqhagamshelana nabasebenzi bezoshishino abafanelekileyo.

I-Q10: ISO 26262, kuphela kwiisekethe ezidibeneyo ezicwangcisiweyo?Akukho mfuneko yeesekethe ezidibeneyo ze-analog kunye ne-interface?
I-A10: Ukuba i-analog kunye neklasi ye-interface yesekethe edibeneyo inomsebenzi wokhuseleko wangaphakathi onxulumene nombono wokhuseleko (oko kukuthi, indlela yokuxilonga kunye nokuphendula ukuthintela ukuphulwa kweenjongo zokhuseleko / iimfuno zokhuseleko), kufuneka ihlangabezane neemfuno ze-ISO 26262.

Q11: Indlela yokhuseleko, ngaphandle kweSihlomelo D seSahlulo sesi-5, ingaba ikhona eminye imigangatho yereferensi?
I-A11: ISO 26262-11: 2018 idwelisa ezinye iindlela zokhuseleko eziqhelekileyo kwiindidi ezahlukeneyo zeesekethe ezidibeneyo.I-IEC 61508-7: 2010 incoma inani leendlela zokhuseleko zokulawula ukungaphumeleli kwe-hardware engahleliwe kunye nokuphepha ukusilela kwenkqubo.

I-Q12: Ukuba isistim iyasebenza ngokukhuselekileyo, ngaba uya kuncedisa ekuphononongeni i-PCB kunye neschematics?
A12: Ngokubanzi, iphonononga kuphela inqanaba loyilo (njengoyilo lweskimu), ingqiqo yemithetho-siseko yoyilo echaphazelekayo kwinqanaba loyilo (njengokulahla uyilo), nokuba iPCB uyilo lwenziwa ngokwemigaqo yoyilo (uyilo. inqanaba aliyi kuhlawula ingqwalasela eninzi).Ingqalelo iya kuhlawulwa kumgangatho woyilo ukukhusela imiba engasebenziyo (umzekelo, i-EMC, i-ESD, njl. njl.) enokuthi ikhokelele ekwaphulweni kokhuseleko olusebenzayo, kunye neemfuno zemveliso, ukusebenza, inkonzo kunye ukuphelelwa lixesha okwaziswe ngexesha lesigaba soyilo.

I-Q13: Emva kokuba ukhuseleko olusebenzayo lugqithiselwe, ngaba isofthiwe kunye ne-hardware ayinakuguqulwa kwakhona, kwaye ukuchasana nokunyamezela kungatshintshwa?
I-A13: Ngokomgaqo, ukuba imveliso egqithise isatifikethi semveliso kufuneka itshintshwe, impembelelo yotshintsho kukhuseleko olusebenzayo kufuneka ihlolwe, kunye nemisebenzi yokuguqulwa koyilo olufunekayo kunye nemisebenzi yokuvavanya kunye nokuqinisekisa kufuneka ihlolwe, ekufuneka ihlolwe. iphinde yavavanywa liqumrhu loqinisekiso lwemveliso.
