STMicroelectronics TN1317 Kev Ntsuas Tus Kheej rau SPC58xNx Ntaus
Taw qhia
Cov ntaub ntawv no muab cov lus qhia txog yuav ua li cas los txhim kho qhov ntsuas tus kheej (STCU2) thiab pib qhov kev xeem tus kheej. Lub STCU2 ntawm SPC58xNx ntaus ntawv tswj hwm ob lub cim xeeb thiab Logic Ua-hauv Kev Ntsuas Tus Kheej (MBIST thiab LBIST) ntawm lub cuab yeej. Cov MBISTs thiab LBISTs tuaj yeem txheeb xyuas qhov ua tsis tiav uas cuam tshuam rau cov kev nco tsis zoo thiab cov logic modules. Tus nyeem ntawv yuav tsum muaj kev nkag siab meej txog kev siv qhov kev xeem tus kheej. Saib Tshooj Lus Ntxiv A rau Cov Cim, cov ntawv luv luv thiab cov ntaub ntawv siv rau cov ntsiab lus ntxiv.
Tshajview
- SPC58xNx txhawb nqa ob qho tib si MBIST thiab LBIST.
- SPC58xNx suav nrog:
- 92 nco txiav (ntawm 0 txog 91)
- LBIST0 (kev nyab xeeb LBIST)
- 6 LBIST rau kev kuaj mob (1) (ntawm 1 txog 6)
LBIST
LBIST rau kev kuaj mob yuav tsum khiav thaum lub tsheb nyob hauv chav nres tsheb thiab tsis yog thaum daim ntawv thov kev nyab xeeb tab tom khiav. Tus nyeem ntawv tuaj yeem sab laj tag nrho cov npe hauv tshooj 7 (Device configuration) ntawm RM0421 SPC58xNx reference manual.
Kev ntsuam xyuas tus kheej
Kev ntsuas tus kheej tuaj yeem khiav hauv online lossis offline hom.
MBIST configuration
- Txhawm rau kom ncav cuag qhov kev lag luam zoo tshaj plaws ntawm kev siv thiab ua tiav lub sijhawm, peb xav kom faib cov MBISTs rau hauv 11 qhov sib cais. Lub MBIST partitions teej tug mus rau tib lub split khiav nyob rau hauv parallel.
- Lub 11 splits khiav nyob rau hauv sequential hom. Rau example:
- tag nrho MBIST partitions teej tug mus rau lub split_0 pib nyob rau hauv parallel;
- Tom qab lawv ua tiav, tag nrho MBIST partitions teej tug mus rau lub split_1 pib nyob rau hauv parallel;
- thiab lwm yam.
- Daim ntawv teev tag nrho ntawm kev sib cais thiab MBISTs tau pom nyob rau hauv kev sib cais thiab DCF Microsoft Excel® phau ntawv ua haujlwm txuas nrog files.
LBIST configuration
- Hauv hom offline, feem ntau tsuas yog LBIST0 khiav, uas yog qhov kev nyab xeeb bist (kom lav ASIL D). Nws yog thawj BIST hauv kev ntsuas tus kheej (pointer 0 hauv LBIST_CTRL register).
- Hauv hom online tus neeg siv tuaj yeem xaiv los khiav lwm LBISTs (los ntawm 1 txog 6) rau kev siv tshuaj ntsuam xyuas. Lawv suav nrog:
- LIS 1: gtm
- LBIST2: hsm, xa, 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: platform
- LBIST6: can0, dma
DCF cov npe rau kev teeb tsa offline
MBISTs thiab LBIST0 tuaj yeem khiav hauv offline mus txog 100 MHz raws li max zaus. DCF Microsoft Excel® phau ntawv ua haujlwm txuas nrog file tshaj tawm cov npe ntawm DCF yuav tsum tau teeb tsa txhawm rau txhawm rau pib MBIST thiab LBIST thaum lub sijhawm khau raj (hom offline). Lawv siv 42 ms.
Saib xyuas thaum kuaj tus kheej
- Ob theem sib txawv cuam tshuam rau qhov kev xeem tus kheej (Saib RM0421 SPC58xNx siv phau ntawv).
- Initialization (configuration loading). SSCM (hom offline) lossis software (online hom) teeb tsa BISTs los ntawm kev ua haujlwm STCU2.
- Kev ntsuas tus kheej. STCU2 ua qhov kev xeem tus kheej.
- Ob tus neeg saib xyuas sib txawv saib xyuas cov theem no.
- Hard-coded watchdog saib xyuas cov theem "initialization". Nws yog kho vajtse saib xyuas teeb tsa ntawm 0x3FF.
- Tus neeg siv tsis tuaj yeem hloov kho nws. Lub moos ntawm hard-coded watchdog nyob ntawm hom kev khiav hauj lwm:
- IRC oscillator hauv hom offline
- STCU2 moos hauv online hom
- Watchdog timer (WDG) saib xyuas "kev sim ua tus kheej". Nws yog kho vajtse saib xyuas teeb tsa los ntawm tus neeg siv (STCU_WDG sau npe). Tus neeg siv tuaj yeem tshawb xyuas qhov xwm txheej ntawm "STCU WDG" tom qab kev ua tiav BIST hauv STCU_ERR_STAT sau npe (WDTO chij).
Lub moos ntawm "STCU WDG" nyob ntawm hom kev ua haujlwm:
- Nws yog configurable los ntawm STCU_PLL (IRC lossis PLL0) hauv hom offline;
- Nws yog configurable los ntawm software hauv online hom.
Hard-coded watchdog refresh thaum pib
Lub sijhawm nyuaj-coded watchdog timeout yog 0x3FF moos cycles. Lub SSCM lossis lub software yuav tsum ua ntu zus rau qhov nyuaj-coded saib xyuas los ntawm programming STCU2 key2. Txhawm rau ua qhov haujlwm no, tus neeg siv yuav tsum cuam tshuam cov npe ntawm DCF cov ntaub ntawv (offline hom) lossis kev sau ntawv nkag mus rau STCU2 cov npe (hom online) nrog rau kev sau rau STCU2 key2 sau npe. Nyob rau hauv cov ntaub ntawv ntawm offline BIST, ib zaug sau ntawm ib tug DCF cov ntaub ntawv yuav siv sij hawm ib ncig ntawm 17 teev cycles. Txij li thaum lub hard-coded watchdog tas sij hawm tom qab 1024 moos cycles, tus neeg siv yuav tsum refresh nws txhua txhua 60 DCF cov ntaub ntawv. Nco tseg: Tus neeg saib xyuas tas sijhawm tom qab 1024 lub voj voog. Ib qho DCF sau ib zaug siv sijhawm 17 teev. STCU2 lees txais txog li 60 DCF cov ntaub ntawv ua ntej lub hard-watchdog tas sij hawm (1024/17 = 60). Nyob rau hauv cov ntaub ntawv ntawm BIST online, lub sij hawm refresh (STCU2 key2 sau) yog daim ntawv thov nyob ntawm.
Online hom configuration
Hauv online hom MBIST cais cov npe tseem zoo ib yam nrog qee qhov kev txwv vim lub neej voj voog. Txhua MBISTs tuaj yeem khiav hauv hom online nkaus xwb hauv ST ntau lawm thiab tsis ua haujlwm tsom xam (FA). Hauv lwm lub neej, HSM/MBIST thiab Flash MBIST tsis siv tau. Hauv qhov no, qhov siab tshaj plaws rau MBIST yog 200 MHz thiab muab los ntawm sys_clock. LBIST rau kev kuaj mob tuaj yeem khiav mus txog 50 MHz, thaum LBIST 0 tuaj yeem khiav mus txog 100 MHz. Hauv qhov no, STCU2 cov ntawv sau npe tuaj yeem teeb tsa nrog "sau npe tus nqi" kab ntawm DCF daim ntawv teev npe file.
Cov ntsiab lus
Hauv SPC58xNx ob leeg MBIST thiab LBIST tuaj yeem khiav. Thaum lub sijhawm offline, LBIST0 thiab tag nrho MBISTs tuaj yeem khiav raws li kev sib cais. Thaum lub sij hawm hauv online, LBIST rau kev kuaj mob tuaj yeem ua haujlwm tau zoo.
