STMicroelectronics TN1317 Self Test Configuration yeSPC58xNx Device
Nhanganyaya
Gwaro iri rinopa nhungamiro pamusoro pekugadzirisa iyo self-test control unit (STCU2) uye wotanga kuzviedza-yega. Iyo STCU2 paSPC58xNx mudziyo inogadzirisa zvese Memory uye Logic Yakavakwa-In Self Test (MBIST uye LBIST) yechishandiso. Iyo MBISTs uye LBISTs inogona kuona kutadza kunonoka kunokanganisa ndangariro dzisina kugadzikana uye logic modules. Muverengi anofanira kuva nekunzwisisa kwakajeka kwekushandiswa kwekuzviedza. Ona Chikamu cheAppendikisi A yeAcronyms, zvipfupiso uye magwaro ereferensi kuti uwane rumwe ruzivo.
Overview
- Iyo SPC58xNx inotsigira ese MBIST neLBIST.
- Iyo SPC58xNx inosanganisira:
- 92 memory cuts (kubva pa0 kusvika 91)
- LBIST0 (iyo yekuchengetedza LBIST)
- 6 LBIST yekuongorora (1) (kubva pa1 kusvika pa6)
LBIST
LBIST yekuongorora inofanirwa kumhanya kana mota iri mugaraji uye kwete panguva yekuchengetedza application. Muverengi anogona kutarisa runyorwa ruzere muchitsauko 7 (Chishandiso kumisikidzwa) yeRM0421 SPC58xNx referensi bhuku.
Self-test configuration
Kuzviedza pachako kunogona kumhanya uri online kana offline mode.
MBIST kugadzirisa
- Kuti usvike pakutengeserana kwakanyanya maererano nekushandisa uye nguva yekuuraya, isu tinokurudzira kupatsanura iyo MBIST muzvikamu gumi nerimwe. Zvikamu zveMBIST zvechikamu chimwe chete chinomhanya chakafanana.
- Iwo gumi nerimwe akapatsanurwa anomhanya mune inoteedzana modhi. For example:
- zvikamu zvese zveMBIST zvekupatsanurwa_0 zvinotanga nenzira dzakafanana;
- mushure mekuurayiwa, zvikamu zvese zveMBIST zvekupatsanurwa_1 zvinotanga zvichifambirana;
- zvichingodaro.
- Rondedzero yakazara yeakapatsanurwa uye MBIST inoratidzwa mukupatsanurwa uye DCF Microsoft Excel® bhuku rebasa rakabatanidzwa files.
LBIST kugadzirisa
- Mune offline mode, kazhinji chete LBIST0 inomhanya, iyo ndiyo yekuchengetedza bhiti (kuvimbisa iyo ASIL D). Ndiyo yekutanga BIST mukuzviedza wega (pointer 0 muLBIST_CTRL register).
- Mune online mode mushandisi anogona kusarudza kumhanya mamwe maLBIST (kubva pa1 kusvika 6) kuti ashandise kuongororwa. Zvinosanganisira:
- LBIST1: gtm
- LBIST2: hsm, yakatumirwa, 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, gomba, ima, cmu_x, adgsar_ana_wrap_x
- LBIST5: chikuva
- LBIST6: anogona0, dma
DCF runyorwa rwekumisikidza pasina Indaneti
MBISTs uye LBIST0 inogona kumhanya isina mhepo kusvika ku100 MHz semax frequency. Iyo DCF Microsoft Excel® bhuku rebasa rakabatanidzwa file inoshuma rondedzero yeDCF kuti igadziriswe kuitira kuti utange iyo MBIST neLBIST panguva yechikamu chebhuot (offline mode). Vanotora anenge 42 ms.
Monitors panguva yekuzviongorora
- Zvikamu zviviri zvakasiyana zvinokanganisa maitiro ekuzviedza (Ona RM0421 SPC58xNx referensi bhuku).
- Kutanga (kugadzirisa kurodha). Iyo SSCM (offline mode) kana software (online mode) inogadzirisa maBIST nekugadzira STCU2.
- Self-test execution. Iyo STCU2 inoita yekuzviedza.
- Imbwa mbiri dzakasiyana dzinotarisa zvikamu izvi.
- Yakaomeswa-coded watchdog inotarisisa chikamu che "kutanga". Iyo imbwa inoona yehardware yakagadzirirwa pa0x3FF.
- Mushandisi haakwanise kuigadzirisa. Iyo wachi yeakaomesesa-coded watchdog inoenderana nemaitiro ekushandisa:
- IRC oscillator iri offline mode
- STCU2 wachi mune online mode
- Watchdog timer (WDG) inotarisisa iyo "yega-yekuzviedza execution". Iyo igadziriso yehardware inogadziriswa nemushandisi (STCU_WDG rejista). Mushandisi anogona kutarisa mamiriro e "STCU WDG" mushure mekuita kweBIST mu STCU_ERR_STAT register (mureza weWDTO).
Wachi ye "STCU WDG" zvinoenderana nemaitiro ekushandisa:
- Iyo inogadziriswa ne STCU_PLL (IRC kana PLL0) mumhepo isina mhepo;
- Iyo inogadziriswa nesoftware mu online mode.
Yakaomeswa-coded watchdog inozorodza panguva yekutanga
Iyo yakaoma-coded watchdog timeout ndeye 0x3FF wachi kutenderera. Iyo SSCM kana software inofanirwa kugara ichizorodza iyo yakaoma-coded watchdog nekugadzira iyo STCU2 kiyi2. Kuti aite oparesheni iyi, mushandisi anofanira kupindira rondedzero yeDCF marekodhi (offline mode) kana kunyora kunopinda kune STCU2 rejista (online mode) nekunyora kune STCU2 key2 rejista. Panyaya yeBIST isina Indaneti, kunyora kamwe chete kwerekodhi yeDCF kunotora nguva dzinenge gumi nenomwe. Sezvo iyo yakaoma-coded watchdog inopera mushure memazana zana nemakumi maviri nemana ewachi, mushandisi anofanirwa kuizorodza makumi matanhatu ega ega DCF marekodhi. Cherechedza: Iyo watchdog inopera mushure me17 wachi. Imwe DCF kunyora inotora gumi nenomwe mawachi. Iyo STCU1024 inogamuchira kusvika makumi matanhatu DCF marekodhi isati yakaoma-watchdog yapera (60/1024 = 17). Panyaya yeBIST yepamhepo, nguva yekuzorodza (STCU2 kiyi60 kunyora) inotsamira pakushandisa.
Online mode configuration
Mune online mode iyo MBIST yakakamurwa runyorwa inoramba yakafanana nezvimwe zvisingakwanisi nekuda kwehupenyu kutenderera. Ese maMBIST anogona kumhanya ari online mode chete muST kugadzira uye kutadza ongororo (FA). Mune mamwe mafambiro ehupenyu, HSM/MBIST neFlash MBIST hazvisvikike. Muchiitiko ichi, iyo yakawanda frequency yeMBIST ndeye 200 MHz uye inopiwa ne sys_clock. Iyo LBIST yekuongorora inogona kumhanya kusvika ku50 MHz, nepo LBIST 0 inogona kumhanya kusvika ku100 MHz. Muchiitiko ichocho, STCU2 marejista anogona kugadzirwa ne "register value" column yeDCF list. file.
Summary
MuSPC58xNx zvese MBIST neLBIST zvinogona kumhanya. Munguva yekunze, LBIST0 uye ese MBIST anogona kumhanya zvinoenderana nekupatsanurwa kumisikidzwa. Munguva yepamhepo modhi, iyo LBIST yekuongorora inogona kumhanya zvakare.
