I-Q9: Uma i-chip idlula i-ISO 26262, kodwa isahluleka ngesikhathi sokusetshenziswa, unganikeza umbiko wokuhluleka, ofana nombiko we-8D wemithetho yemoto?
A9: Abukho ubudlelwano obudingekayo phakathi kokuhluleka kwe-chip nokuhluleka kwe-ISO 26262, futhi kunezizathu eziningi zokuhluleka kwe-chip, okungenzeka kube ngaphakathi noma ngaphandle.Uma isigameko sokuphepha sibangelwa ukwehluleka kwe-chip ohlelweni oluhlobene nokuphepha ngesikhathi sokusetshenziswa, kuhlobene no-26262. Njengamanje, kuneqembu lokuhlaziya ukwehluleka, elingasiza amakhasimende ukuthola imbangela yokuhluleka kwe-chip, futhi ungaxhumana nezisebenzi zebhizinisi ezifanele.
I-Q10: ISO 26262, yamasekethe ahlanganisiwe ahlelelekayo kuphela?Azikho izidingo zamasekethe ahlanganisiwe we-analog nesixhumi esibonakalayo?
I-A10: Uma isifunda esihlanganisiwe sesigaba se-analogi nesixhumi esibonakalayo sinomshini wokuphepha wangaphakathi ohlobene nomqondo wokuphepha (okungukuthi, indlela yokuxilonga neyokuphendula ukuze kuvinjelwe ukuphulwa kwezinjongo zokuphepha/izimfuneko zokuphepha), idinga ukuhlangabezana nezimfuneko ze-ISO 26262.
Q11: Indlela yokuvikela, ngaphandle kweSithasiselo D Sengxenye5, ingabe akhona amanye amazinga okuyisethenjwa?
I-A11: ISO 26262-11:2018 ibala ezinye izindlela zokuphepha ezivamile zezinhlobo ezahlukene zamasekethe ahlanganisiwe.I-IEC 61508-7:2010 incoma izindlela zokuphepha eziningi zokulawula ukwehluleka okungahleliwe kwehadiwe kanye nokugwema ukwehluleka kwesistimu.
Q12: Uma uhlelo lusebenza ngokuphephile, ungasiza ekubuyekezeni i-PCB nezikimu?
I-A12: Ngokujwayelekile, ibuyekeza kuphela izinga lokuklama (njengokuklama kwesikimu), ubuhlakani bezinye izimiso zokuklama ezithintekayo ezingeni lokuklama (njengokwehliswa kwedizayini), nokuthi ingabe ukwakheka kwe-PCB kwenziwa ngokwezimiso zokuklama (isakhiwo). izinga ngeke linake kakhulu).Kuzogxilwa futhi ezingeni lokuklama ukuvimbela izici ezingasebenzi (isb., EMC, ESD, njll.) ezingase ziholele ekwephulweni kokuphepha kokusebenza, kanye nezidingo zokukhiqiza, ukusebenza, isevisi, kanye ukuphelelwa yisikhathi okwethulwe ngesikhathi sesigaba sokuklama.
I-Q13: Ngemuva kokuthi ukuphepha okusebenzayo kudlulisiwe, ingabe isofthiwe ne-hardware ngeke kusalungiswa, noma ukumelana nokubekezelelana kungashintshwa?
I-A13: Empeleni, uma umkhiqizo ophumelele isitifiketi somkhiqizo udinga ukushintshwa, umthelela wenguquko ekuphepheni kokusebenza kufanele uhlolwe, futhi imisebenzi edingekayo yoshintsho lwedizayini nemisebenzi yokuhlola nokuqinisekisa kufanele ihlolwe, okudingeka ihlolwe. ihlolwe kabusha yindikimba enikeza izitifiketi zomkhiqizo.
