Isinyathelo se-Google sivumela ukukhiqizwa kwamahhala kwamaqoqo okuhlola ama-chip avuliwe

Muva nje Kuvele izindaba i-Google ehlangene nazo izinkampani zokukhiqiza I-SkyWater Technology ne-Efabless izokwethula umkhankaso lokho kuvumela abathuthukisi behadiwe yomthombo ovulekile ukuthi bakhe ama-chip abawathuthukisayo ngokukhululeka.

Isinyathelo ihlose ukugqugquzela ukuthuthukiswa kwehadiwe evulekile, nciphisa izindleko ezivulekile zokuthuthukiswa kwephrojekthi futhi wenze kube lula ukuxhumana nezitshalo ezikhiqizayo.

Siyabonga ngesinyathelo noma ubani angaqala ukuzakhela ama-chips akhe ngaphandle kokwesaba izindleko eziphezulu zokukhiqiza ama-prototypes okuqala. I-Google ikhokhela zonke izindleko zokukhiqiza, ukupakisha, nezokuthumela.

Izicelo zokufakwa kuhlelo lokukhiqiza lwamahhala ingathunyelwa njalo ezinyangeni ezimbili. Indawo eseduze izovala ngoJuni 8, kanti ama-chips akwazi ukungena azobe elungile ngo-Agasti 30 futhi azothunyelwa kubabhali ngo-Okthoba 18.

Ezicelweni ezifakiwe, amaphrojekthi angama-40 akhethiwe (Uma kunezicelo ezingaphansi kuka-40 ezithunyelwe, zonke lezo eziphase ukulawulwa kokulungisa zizofakwa ekukhiqizweni). Ngokusekelwe emiphumeleni yokukhiqiza, umthuthukisi uzothola ama-chips angu-50 namabhodi angu-5 anama-chips afakiwe.

ama-TLDRs; Ithimba le-Google Hardware Toolchains lethula ingosi entsha kanjiniyela, developer.google.com/silicon , ukusiza umphakathi wonjiniyela ukuthi uqalise ngohlelo lwabo lwezokuthutha oluvulekile lwe-MPW. Lokhu kuzovumela noma ubani ukuthi athumele imiklamo ye-IC yomthombo ovulekile ukuze yenziwe ngaphandle kwezindleko.

Kusukela ngoNovemba 2020, lapho i-Skywater Technologies imemezela ubudlelwano bayo ne-Google ukuze ivule Ikhithi Yokuklama Inqubo ye-SKY130 process node, ithimba le-Hardware Toolchains lapha e-Google belisohambweni lokwenza ukwakhiwa kwe-silicon okuvulekile kufinyeleleke kubo bonke onjiniyela. Ukufinyelela kumthombo ovulekile kanye ne-PDK ekhiqizwayo kushintsha isimo esikhona embonini yedizayini ye-silicon yangokwezifiso nezemfundo:
Abaklami manje sebekhululekile ukuqala amaphrojekthi abo mahhala ku-NDA nemikhawulo yokusetshenziswa.
Abacwaningi bangenza ucwaningo lwabo luphinde lukhiqizwe ngontanga yabo.
Amathuluzi e-EDA omthombo ovulekile angahlanganiswa ngokujulile nenqubo yokukhiqiza

Izicelo zamaphrojekthi asatshalaliswe ngokugcwele ngaphansi kwamalayisensi avulekile ezamukelwayo, engasindwa yizivumelwano zokungadaluli (i-NDA) futhi ezingakhawuleli ububanzi bemikhiqizo yazo.

I-Google inikeze ithuba lokukhiqizwa kwamahhala kwamaqoqo okuhlola ama-chip

Idatha yokukhiqizwa kufanele idluliselwe ngefomethi ye-GDSII, iphumelele i-suite yokuhlola enikeziwe, futhi ikhiqizwe kabusha kusukela kumafayela ephrojekthi okuqala (okungukuthi ukumemezela iphrojekthi evuliwe, kodwa ngeke kusebenze ukudlulisa umklamo wobunikazi ekukhiqizeni).

Iphrojekthi ngayinye inendawo engashintshi engu-2,92mm x 3,52mm yomsebenzisi kanye nezikhonkwane ze-I/O ezingu-38 kumahhanisi achazwe kusengaphambili ukuze uqinise umklamo wakho. Iphinde ibe nengqalasizinda yokuhlola edingekayo ukuze kuqinisekiswe ukucaciswa nokuziphatha kwe-chip ngaphambi kokuba ithunyelwe ukuze irekhodwe.

Ukwenza kube lula ukuthuthukiswa kwe-chip evulekile, amathuluzi alandelayo avulekile anikeziwe:

  • I-SkyWater PDK (Process Design Kit), ikhithi yamathuluzi echaza inqubo yokwenza i-130nm (SKY130) esetshenziswa efekthri ye-SkyWater futhi ikuvumela ukuthi ulungise amafayela omklamo adingekayo ekukhiqizeni ama-chip.
  • I-OpenLane isethi yezingxenye zokuguqulwa okuzenzakalelayo kwamasekhethi e-ASIC RTL abe yifomethi ye-GDSII esetshenziswa ezimbonini zama-chip.
  • I-XLS (Accelerated HW Synthesis) iyisethi yamathuluzi ohlanganisa amafayela ephrojekthi ane-chip hardware padding ehambisana nencazelo yezinga eliphezulu enikeziwe yokusebenza okudingekile, eklanywe ngesitayela sokuthuthukiswa kwesofthiwe.
  • Isethi yemithetho yesistimu yokuhlanganisa i-Bazel esekelwa amathuluzi avulekile (i-Yosys, i-Verilator, i-OpenROAD) yokusebenza ngezilimi ezichaza ihadiwe (i-Verilog, VHDL, Chisel, nMigen).
  • I-OpenROAD iwuhlaka lokuzenzakalela inqubo yokuthuthukiswa kwesekethe evulekile.
  • I-Verible isethi yamathuluzi okuthuthukiswa kwe-Verilog, okuhlanganisa umhlaseli, isistimu yokufometha yesitayela, ne-linter.
