Q9: Kana iyo chip ikapfuura ISO 26262, asi ichiri kutadza panguva yekushandiswa, iwe unogona here kupa mushumo wekukundikana, wakafanana ne8D mushumo wemirairo yemotokari?
A9: Hapana hukama hunodiwa pakati pekukundikana kwechip uye kukundikana kwe ISO 26262, uye kune zvikonzero zvakawanda zvekukundikana kwechip, izvo zvingave mukati kana kunze.Kana chiitiko chekuchengetedza chinokonzerwa nekukundikana kwechiputi muhutano hwakabatana nekuchengetedzwa panguva yekushandiswa, inoenderana ne26262. Parizvino, pane kukundikana kwekuongorora boka, iyo inogona kubatsira vatengi kuwana chikonzero chekukundikana kwechiputi, uye iwe unogona kubata akakodzera bhizinesi vashandi.
Q10: ISO 26262, chete yemapurogiramu akabatanidzwa akabatanidzwa?Hapana zvinodiwa zveanalog uye interface yakabatanidzwa maseketi?
A10: Kana iyo analog uye interface kirasi yakabatanidzwa yedunhu ine yemukati yekuchengetedza meshini ine chekuita neiyo pfungwa yekuchengetedza (kureva, yekuongorora uye yekupindura nzira yekudzivirira kutyorwa kwekuchengetedza zvinangwa / kuchengetedza zvinodiwa), inoda kuzadzisa ISO 26262 zvinodiwa.
Q11: Chengetedzo michina, kunze kweAppendix D yeChikamu5, pane mamwe mareferensi mazinga here?
A11: ISO 26262-11: 2018 inonyora mamwe maitiro akajairika ekuchengetedza emhando dzakasiyana dzemaseketi akabatanidzwa.IEC 61508-7: 2010 inokurudzira akati wandei nzira dzekuchengetedza dzekudzora kusarongeka kwehardware kutadza uye kudzivirira kutadza kwehurongwa.
Q12: Kana iyo sisitimu ichishanda yakachengeteka, iwe uchabatsira mukuongorora iyo PCB uye schematics?
A12: Kazhinji, inongoongorora chete dhizaini dhizaini (senge dhizaini yedhizaini), kurongeka kwemamwe magadzirirwo emisimboti ane chekuita nedanho rekugadzira (senge derating dhizaini), uye kuti PCB marongerwo anoitwa zvinoenderana nemisimboti yekugadzira (kurongeka. nhanho haizobhadhara zvakanyanya).Attention ichabhadharwawo kune iyo dhizaini nhanho yekudzivirira isiri-inoshanda yekutadza zvinhu (semuenzaniso, EMC, ESD, nezvimwewo) izvo zvinogona kutungamira mukutyorwa kwekuchengetedza kwekuchengetedza, pamwe nezvinodiwa zvekugadzira, kushanda, sevhisi, uye. obsolescence yakaunzwa panguva yekugadzira chikamu.
Q13: Mushure mekuchengetedzwa kwekushanda kwapfuura, software nehardware hazvigone kugadziridzwa zvakare, uye kuramba uye kushivirira hazvigone kuchinjwa here?
A13: Muchidimbu, kana chigadzirwa chapfuura chitupa chechigadzirwa chichida kuchinjwa, mabatiro eshanduko pakuchengetedza mashandiro anofanirwa kuongororwa, uye inodiwa dhizaini yekuchinja zviitiko uye yekuyedza uye yekuona zviitiko zvinofanirwa kuongororwa, izvo zvinofanirwa kuongororwa. yakaongororwazve neboka rezvitupa zvechigadzirwa.
