STMicroelectronics TN1317 Nhazi nnwale onwe maka ngwaọrụ SPC58xNx

Okwu mmalite

Akwụkwọ a na-enye ntuziaka gbasara otu esi ahazi ngalaba njikwa nyocha onwe (STCU2) wee malite ogbugbu onwe onye. STCU2 dị na ngwaọrụ SPC58xNx na-ejikwa ma ebe nchekwa na nyocha nke onwe (MBIST na LBIST) nke ngwaọrụ ahụ. MBISTs na LBIST nwere ike ịchọpụta ọdịda latent nke na-emetụta ihe ncheta na-agbanwe agbanwe yana modul ezi uche. Onye na-agụ kwesịrị inwe nghọta doro anya maka ojiji nke nyocha onwe onye. Lee Nkebi Ihe Mgbakwunye A maka Mkpebi, mkpirisi na akwụkwọ ntụaka maka nkọwa ndị ọzọ.

  • SPC58xNx na-akwado ma MBIST na LBIST.
  • SPC58xNx gụnyere:
    •  Mbelata ebe nchekwa 92 (site na 0 ruo 91)
    •  LBIST0 (LBIST nchekwa)
    •  6 LBIST maka nchọpụta ọrịa (1) (site na 1 ruo 6)

LBIST maka nchọpụta ọrịa kwesịrị ịgba ọsọ mgbe ụgbọ ala dị n'ime ebe a na-adọba ụgbọala ọ bụghị mgbe ngwa nchekwa na-agba ọsọ. Onye na-agụ nwere ike ịlele ndepụta zuru oke na isi nke 7 (Nhazi ngwaọrụ) nke akwụkwọ ntuziaka RM0421 SPC58xNx.

Nhazi nyocha nke onwe

Nnwale onwe onye nwere ike ịgba ọsọ na ntanetị ma ọ bụ na-anọghị n'ịntanetị.

Nhazi MBIST

  • Iji nweta azụmaahịa kachasị mma n'ihe gbasara oriri na oge igbu oge, anyị na-akwado ikewa MBIST n'ime nkewa iri na otu. Akụkụ MBIST nke nwere otu nkewa na-aga n'otu n'otu.
  • Nkewa iri na otu na-agba n'usoro usoro. Maka exampLe:
  •  Akụkụ MBIST niile bụ nke split_0 na-amalite n'otu n'otu;
  •  Mgbe e gbuchara ha, akụkụ MBIST niile bụ nke split_1 na-amalite n'otu n'otu;
  •  na ihe ndị ọzọ.
  • A na-egosi ndepụta zuru oke nke nkewa na MBIST na nkewa na DCF Microsoft Excel® akwụkwọ ọrụ files.

Nhazi LBIST

  • Na ọnọdụ na-anọghị n'ịntanetị, n'ozuzu naanị LBIST0 na-agba, nke ahụ bụ bist nchekwa (iji kwado ASIL D). Ọ bụ BIST mbụ na nhazi ule onwe onye (ntụ aka 0 na ndebanye aha LBIST_CTRL).
  • Na ọnọdụ ịntanetị onye ọrụ nwere ike họrọ ịgba ọsọ LBIST ndị ọzọ (site na 1 ruo 6) maka iji nyocha. Ha gụnyere:
    •  LBIST1: gtm
    •  LBIST2: hsm, zitere, 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
    •  LBIST4: psi5_1, ethernet0, adcsar_dig_x, adcsar_dig_x, iic, dspi_x, adcsar_seq_x, adcsar_seq_x, linlfex_x, pit, ima, cmu_x, adgsar_ana_wrap_x
    •  LBIST5: ikpo okwu
    •  LBIST6: can0, dma

Ndepụta DCF maka nhazi na-anọghị n'ịntanetị

MBIST na LBIST0 nwere ike ịgba ọsọ na ntanetị ruo 100 MHz dị ka ugboro kachasị. Akwunyere akwụkwọ ọrụ DCF Microsoft Excel® file na-akọ ndepụta nke DCF ga-ahazi ka ịmalite MBIST na LBIST n'oge usoro buut (ụdị offline). Ha na-ewe ihe dịka 42 ms.

  • Usoro abụọ dị iche iche na-emetụta nnwale nke onwe (Lee akwụkwọ ntuziaka RM0421 SPC58xNx).
  •  Mmalite (nkwado nhazi). SSCM (ọnọdụ na-anọghị n'ịntanetị) ma ọ bụ ngwanro (ụdị ntanetị) na-ahazi BIST site na ịhazi STCU2.
  •  Nnwale nke onwe. STCU2 na-eme nnwale onwe onye.
  • Ndị nche abụọ dị iche iche na-enyocha usoro ndị a.
  •  Ndị nche nwere koodu siri ike na-enyocha usoro “mmalite”. Ọ bụ ihe nchekwa ngwaike ahaziri na 0x3FF.
  • Onye ọrụ enweghị ike ịgbanwe ya. Elekere nke ihe nchekwa koodu siri ike dabere na ọnọdụ ọrụ:
    •  IRC oscillator na ọnọdụ offline
    •  Elekere STCU2 na ọnọdụ ịntanetị
  • Watchdog ngụ oge (WDG) na-enyocha "nnwale onwe onye". Ọ bụ ihe nleba anya ngwaike nke onye ọrụ nwere ike ịhazi ya (akwụkwọ STCU_WDG). Onye ọrụ nwere ike ịlele ọkwa nke "STCU WDG" ka emechara BIST na ndekọ STCU_ERR_STAT (ọkọlọtọ WDTO).

Elekere nke "STCU WDG" dabere na ọnọdụ ọrụ:

  •  Enwere ike ịhazi ya site na STCU_PLL (IRC ma ọ bụ PLL0) na ọnọdụ offline;
  •  Enwere ike ịhazi ya site na ngwanrọ na ọnọdụ ịntanetị.

Nledo nchekwa nwere koodu ume ọhụrụ n'oge mbido

Oge nleba anya nwere koodu siri ike bụ okirikiri elekere 0x3FF. SSCM ma ọ bụ sọftụwia ahụ ga-emerịrị ka ndị na-ahụ maka nchekwa nwere koodu ume kwa oge site na imezi STCU2 igodo2. Iji rụọ ọrụ a, onye ọrụ ga-ahapụrịrị ndepụta ndekọ ndekọ DCF (ọnọdụ na-anọghị n'ịntanetị) ma ọ bụ idebanye aha na ndekọ STCU2 (ụdị ịntanetị) site na iji dee na ndekọ STCU2 key2. N'ihe banyere BIST na-anọghị n'ịntanetị, otu ederede ndekọ DCF na-ewe ihe dị ka okirikiri elekere iri na asaa. Ebe nchekwa nchekwa nwere koodu na-ekubi ume ka elekere 17 gachara, onye ọrụ ga-eme ka ọ dị ọhụrụ na ndekọ 1024 DCF ọ bụla. Mara: Onye nche na-ekubi ume ka elekere 60 gachara. Otu ederede DCF na-ewe okirikiri elekere iri na asaa. STCU1024 na-anabata ihe ndekọ ruo 17 DCF tupu onye nche ike agwụ (2/60 = 1024). N'ihe gbasara BIST n'ịntanetị, oge ume ọhụrụ (STCU17 key60 ide) dabere na ngwa.

Nhazi ọnọdụ ịntanetị

Na ọnọdụ ịntanetị, ndepụta nkewa MBIST ka dị otu na oke ụfọdụ n'ihi okirikiri ndụ. MBIST niile nwere ike ịgba ọsọ na ọnọdụ ịntanetị naanị na mmepụta ST na nyocha ọdịda (FA). N'ime usoro ndụ ndị ọzọ, HSM/MBIST na Flash MBIST adịghị enweta. N'okwu a, ugboro kachasị maka MBIST bụ 200 MHz ma sys_clock na-enye ya. LBIST maka nchọpụta ọrịa nwere ike ịgba ọsọ ruo 50 MHz, ebe LBIST 0 nwere ike ịgba ọsọ ruo 100 MHz. N'okwu ahụ, enwere ike ịhazi ndekọ STCU2 na kọlụm "ọnụahịa ndebanye aha" nke ndepụta DCF. file.

Nchịkọta
Na SPC58xNx ma MBIST na LBIST nwere ike ịgba ọsọ. N'oge na-anọghị n'ịntanetị, LBIST0 na MBIST niile nwere ike ịgba ọsọ dabere na nhazi nkewa. N'oge usoro ịntanetị, LBIST maka nchọpụta ọrịa nwekwara ike ịgba ọsọ.
