MILLION DOLLAR DREAM.

Koj puas tau npau suav txog muaj koj tus kheej tester IC hauv tsev? Tsis yog tsuas yog lub cuab yeej uas tuaj yeem sim IC, tab sis lub tshuab "programmable" uas zoo li yog ib yam khoom lag luam ntawm cov neeg siv khoom loj tshaj plaws hauv kev lag luam semicon xeem, xws li Teradyne, Advantest, Verigy lossis Nextest.

Tam sim no koj tuaj yeem!

Kev nce qib hauv thev naus laus zis ntawm FPGA ua rau cov tuam txhab tsim khoom ntim cov khoom loj hauv ib qho nti ntawm tus nqi pheej yig. Ua ke nrog qhov kev hloov pauv tam sim no hauv cov khoom siv hluav taws xob mus rau kev hloov kho, thiab yam koj tau txais yog qhov pheej yig, "programmable" IC tester uas koj tuaj yeem tsim hauv tsev siv cov cuab yeej hauv koj chav ua noj. Thiab qhov zoo tshaj yog qhov nws "zoo li qhov tseeb" los ntawm Teradyne lossis Nextest.

VIM LI CAS XWB NAWB!

Qhov ntawd yog lo lus nug lab daus las. Qhov kev vam meej ruaj khov hauv thev naus laus zis thev naus laus zis thiab kev koom tes ntawm cov tuam txhab tsim khoom me me uas tsim cov qauv tsim muaj txiaj ntsig zoo, txhawb nqa cov neeg nyiam ua haujlwm tshiab los ua lawv tus kheej cov khoom siv ntxim nyiam. Qhov tseeb, tus kws tshaj lij nyiam ua haujlwm txawm tias tuaj yeem tsim nws tus kheej lub xov tooj ntawm tes los ntawm cov khoom lag luam tawm, uas tsis tuaj yeem ua rau tus hobbyist ua 12 xyoo rov qab. Tib txoj kev nce qib hauv cov khoom siv hluav taws xob tuaj yeem ua rau cov neeg sim ntsuas ib nrab. Kuv tau tos, uas muaj ib hnub kuv tuaj yeem yuav kuv tus kheej lub ntsuas tes los ntawm ebay, tab sis zoo li nws tsis tshwm sim. Tsis muaj leej twg ua rau nws tshwm sim. Ib tus neeg yuav tsum ua kom nws tshwm sim. Yog li no, kuv nyob ntawm no. Pib kom tau pob dov. Kev tshoov siab ib tug neeg tawm mus saib nws txias npaum li cas, thiab nws tus kheej ua tus qauv zoo dua. Thiab tom qab ntawd lwm tus tsim tus qauv zoo dua. Txhua version tau txais peb ib kauj ruam ze dua ntawm SKYNET. Xijpeem, Kuv cia siab tias kuv tuaj yeem dhau los ua "Steve Wozniak" ib hnub twg.

QHOV TSEEB: Renegade-i tester, thawj zaug hauv ib kab

Cov lus qhia no yuav qhia koj yuav ua li cas tsim koj tus kheej tester siv cov khoom lag luam tawm ntawm lub txee.

Kauj Ruam 1: Kev tsim kho

Ua raws cov lus qhia hauv ConstructionGuide.pdf los tsim kho vajtse. Schematics hauv pdf.

Cov Nqi Ntawm Cov Khoom

• 1 pc DE0-Nano version-1 tus kws qhia khoom siv (siv ua lub tshuab ntsuas)
• 1 pc USB-rau-RS232TTL hloov pauv (siv los ntsuas lub npav)
• 1 pc USB txuas txuas
• 3 pcs perforated PCB rau tes thaiv (siv rau PE cov laug cam thiab cov khoom thauj khoom)
• 1 pc CD74HC4066 lub xeev hloov khoom siv (siv ua DPS txuas txuas txuas)
• 1 pc 14-pin IC qhov (kom tuav 74hc4066)
• 17 pcs 2N7000 FET transistors (siv ua Pin Electornics)
• 2 pcs 0.1uF/50V capacitors
• 34 pcs 10Kohms/0.25watt resistors
• 1 pc 5-tus pin header txuas poj niam (siv txuas USB-RS232TTL hloov pauv)
• 2 pcs 40-pin header connector poj niam (siv los txuas rau DE0-Nano GPIO cov chaw nres nkoj)
• 2 pcs 24-pin header connector poj niam (siv los ua Test Headers 0 & 1)
• 2 pcs 24-pin header connector txiv neej (siv los txuas lub loadboard rau Test Header 0 & 1)
• 1 pc textool ic socket (siv los tuav Lub Ntaus Hauv Kev Xeem)

Kauj Ruam 2: Kev teeb tsa (Softwares thiab Tsav Tsheb)

Ua raws li cov lus qhia hauv InstallationGuide.pdf txhawm rau nruab cov software thiab cov tsav tsheb.

Cov software:

• Quartus II (DVD suav nrog hauv DE0-Nano lub thawv)
• LibreOffice 5 (rub tawm los ntawm w w w libreoffice. Org)
• Renegade-i Software (txuas hauv cov lus qhia no)

Tsav tsheb:

• USB-Blaster (suav nrog hauv Quartus II software)
• USB-UART-TTL tus tsav tsheb (tus muag khoom uas koj yuav lub cuab yeej yuav muab ib qho)

Kauj ruam 3: Pib

Qhia saum toj no yog Screenshot ntawm cov ntaub ntawv teev npe ntawm Quadsite qhov kev xeem program:

Ua raws cov lus qhia hauv UserGuide.pdf kom pib. Tau txais qee qhov SN74LS08, SN74LS00, SN74LSXX, AT24C02 cov lej eeproms, tom qab ntawd rho tawm cov qauv ntsuas qhov kev zov me nyuam txuas nrog hauv cov lus qhia no. Tsim cov khoom thauj khoom piav qhia hauv SN74LSXXLoadboard.pdf (thiab xaiv tau AT24C02Loadboard.pdf). Nyeem ProgrammingGuide.pdf kom paub zoo tias yuav sau qhov program li cas. Yog tias koj xav dhau los ua tus kws tshaj lij sim thiab tsom mus rau txoj haujlwm ntawm Intel (Amkor, Stats, Asat, Utac, TI, thiab lwm yam), txiav txim siab nqis peev hauv chav kawm uas tau qhia los ntawm w w w. mos-xeem. com tom qab ntawv thov thiab xyaum ua tej yam uas koj tau kawm siv qhov Renegade-i tester no.

• Koj thawj txoj haujlwm: Hloov kho qhov piv txwv piv txwv uas tau muab rau LS08 los ntsuas 74LS32 & 74LS02.
• Koj txoj haujlwm thib ob: Yuav ua li cas txog 74LS74, koj puas tuaj yeem ua tau? (Hint: siv RTZ rau clk pins)
• Koj txoj haujlwm thib peb: Tsim lub thav duab los ntsuas ESP-01, sau qhov kev xeem. Los, koj tuaj yeem ua tau.

Yog li, muaj pes tsawg hom sib txawv ntawm IC tuaj yeem sim hauv Renegade-i? pua pua? Txhiab? Tsheej lab?
