Tsarin gwajin kai-da-kai

Gwajin kai na iya gudana ko dai a cikin layi ko yanayin layi.

Tsarin MBIST

• Don isa mafi kyawun ciniki dangane da amfani da lokacin aiwatarwa, muna ba da shawarar raba MBIST zuwa rarrabuwa 11. Bangarorin MBIST na cikin tsaga guda ɗaya suna gudana a layi daya.
• Rarraba guda 11 suna gudana cikin yanayin jeri. Don misaliampda:
•  duk sassan MBIST na cikin split_0 suna farawa a layi daya;
•  bayan an aiwatar da su, duk sassan MBIST na tsaga_1 suna farawa a layi daya;
•  da sauransu.
• An nuna cikakken jerin rarrabuwar kawuna da MBISTs a cikin tsaga kuma an haɗe littafin aikin DCF Microsoft Excel® files.

Tsarin LBIST

• A cikin yanayin layi, gabaɗaya LBIST0 kawai ke gudana, wato amintaccen bist (don tabbatar da ASIL D). Ita ce BIST ta farko a cikin tsarin gwajin kai (mai nuni 0 a cikin rijistar LBIST_CTRL).
• A cikin yanayin kan layi mai amfani zai iya zaɓar gudanar da sauran LBISTs (daga 1 zuwa 6) don amfanin bincike. Sun hada da:
  •  LBIST1: gtm
  •  LBIST2: hsm, aika, emios0, psi5, dspi
  •  LBIST3: can1, flexray_0, memu, emios1, psi5_0, fccu, ethernet1, adcsd_ana_x, crc_0, crc_1, fosu, cmu_x, bam, adcsd_ana_x

Jerin DCF don daidaitawar layi

MBISTs da LBIST0 na iya aiki cikin layi har zuwa 100 MHz a matsayin max mitar. Littafin aikin DCF Microsoft Excel® haɗe file yana ba da rahoton jerin abubuwan DCF da za a daidaita su don farawa MBIST da LBIST yayin lokacin taya (yanayin layi). Suna ɗaukar kusan 42 ms.

Saka idanu yayin gwajin kai

• Hanyoyi guda biyu daban-daban suna tasiri aikin gwajin kai (Duba littafin tunani na RM0421 SPC58xNx).
•  Ƙaddamarwa (nau'in daidaitawa). SSCM (yanayin layi) ko software (yanayin kan layi) yana daidaita BISTs ta hanyar tsara STCU2.
•  Kisa na gwada kai. STCU2 yana aiwatar da gwajin kai.
• Masu sa ido biyu daban-daban suna lura da waɗannan matakan.
•  Mai sa ido mai ƙarfi yana lura da lokacin “farawa”. Katin kayan aiki ne wanda aka saita a 0x3FF.
• Mai amfani ba zai iya gyara shi ba. Agogon ma'ajiya mai lamba ya dogara da yanayin aiki:
  •  IRC oscillator a yanayin layi
  •  Agogon STCU2 a yanayin kan layi
• Watchdog timer (WDG) yana lura da "kisa-gwajin-kai". Mai sa ido na kayan masarufi ne wanda mai amfani zai iya daidaita shi (rejistar STCU_WDG). Mai amfani zai iya duba matsayin "STCU WDG" bayan aiwatar da BIST a cikin rajistar STCU_ERR_STAT (tutar WDTO).

Agogon "STCU WDG" ya dogara da yanayin aiki:

•  Ana iya daidaita shi ta hanyar STCU_PLL (IRC ko PLL0) a yanayin layi;
•  Ana iya daidaita shi ta software a yanayin kan layi.

Wartsakar da masu sa ido mai ƙarfi yayin farawa

Matsakaicin lokacin karewa mai ƙarfi shine kewayawar agogo 0x3FF. SSCM ko software dole ne lokaci-lokaci su wartsake mai sa ido mai ƙarfi ta hanyar tsara maɓallin STCU2. Don yin wannan aikin, mai amfani dole ne ya shiga cikin jerin bayanan DCF (yanayin layi) ko rubuta damar shiga rajistar STCU2 (yanayin kan layi) tare da rubuta zuwa rajistar maɓalli na STCU2. A cikin yanayin BIST na layi, rubuta guda ɗaya na rikodin DCF yana ɗaukar kewayen agogo 2. Tunda mai sa ido mai ƙarfi ya ƙare bayan zagayowar agogo 2, mai amfani dole ne ya sabunta shi kowane rikodin 17 DCF. Lura: Mai sa ido zai ƙare bayan zagayowar agogo 1024. Rubutun DCF guda ɗaya yana ɗaukar hawan agogo 60. STCU1024 yana karɓar rikodin har zuwa 17 DCF kafin mai sa ido ya ƙare (2/60 = 1024). A cikin yanayin BIST na kan layi, lokacin wartsakewa (STCU17 key60 rubutun) ya dogara da aikace-aikace.

Tsarin yanayin kan layi

A cikin yanayin kan layi jerin raba MBIST ya kasance iri ɗaya tare da wasu iyakoki saboda yanayin rayuwa. Duk MBISTs na iya gudana a cikin yanayin kan layi kawai a cikin samarwa da bincike na gazawar ST (FA). A cikin sauran zagayowar rayuwa, HSM/MBIST da Flash MBIST ba su samuwa. A wannan yanayin, matsakaicin mitar MBIST shine 200 MHz kuma ana bayar da shi ta sys_clock. LBIST don bincike na iya aiki har zuwa 50 MHz, yayin da LBIST 0 zai iya gudana har zuwa 100 MHz. A wannan yanayin, ana iya daidaita rajistar STCU2 tare da ginshiƙin "ƙimar rajista" na jerin DCF. file.

Takaitawa
A cikin SPC58xNx duka MBIST da LBIST na iya gudana. A lokacin layi, LBIST0 da duk MBISTs na iya gudana bisa ga tsagawar tsarin. Yayin yanayin kan layi, LBIST don ganowa na iya gudana shima.
