Google, hauv kev koom tes nrog cov tuam txhab tsim khoom SkyWater Technology thiab Efabless, tau pib ua haujlwm uas tso cai rau cov neeg tsim kho kho vajtse qhib ua cov chips lawv tsim dawb. Lub hom phiaj yog txhawm rau txhawb kev txhim kho ntawm cov khoom siv qhib, txo cov nqi ntawm kev tsim cov haujlwm qhib thiab ua kom yooj yim sib cuam tshuam nrog kev tsim cov nroj tsuag. Ua tsaug rau qhov pib, leej twg tuaj yeem pib tsim lawv tus kheej cov chips kev cai yam tsis ntshai tus nqi siab ntawm kev tsim cov qauv pib. Tag nrho cov nqi tsim khoom, ntim thiab xa khoom yog them los ntawm Google.
Cov ntawv thov rau kev suav nrog hauv qhov kev tsim khoom pub dawb tuaj yeem xa tuaj ib zaug txhua ob lub hlis. Qhov ze tshaj plaws yuav raug kaw rau lub Rau Hli 8, thiab cov chips uas tswj tau mus rau hauv nws yuav npaj tau rau lub Yim Hli 30 thiab xa mus rau cov kws sau ntawv thaum Lub Kaum Hli 18. Los ntawm cov ntawv thov xa tuaj, 40 qhov haujlwm raug xaiv (yog tias daim ntawv thov xa tawm tsawg dua 40, tom qab ntawd tag nrho cov uas tau dhau qhov kev kuaj xyuas raug yuav raug muab tso rau hauv ntau lawm). Raws li cov txiaj ntsig kev tsim khoom, tus tsim tawm yuav tau txais 50 chips thiab 5 boards nrog cov chips ntsia.
Cov ntawv thov raug lees txais tsuas yog los ntawm cov haujlwm uas tau muab faib rau hauv cov ntawv tso cai qhib, tsis muaj kev cuam tshuam los ntawm cov ntawv cog lus tsis qhia tawm (NDAs) thiab tsis txwv qhov kev siv ntawm lawv cov khoom. Cov ntaub ntawv rau kev tsim khoom yuav tsum raug xa mus rau hauv GDSII hom, dhau qhov kev sim teeb tsa thiab muab rov ua dua los ntawm cov ntaub ntawv tsim tawm (piv txwv li, xa qhov qhib qhov project, tab sis koj yuav tsis tuaj yeem xa cov qauv tsim rau kev tsim khoom).
Txhawm rau ua kom yooj yim qhib nti kev txhim kho, cov cuab yeej qhib hauv qab no muaj:
- SkyWater PDK (Process Design Kit), cov khoom siv uas piav qhia txog 130nm technical process (SKY130) siv ntawm SkyWater cog thiab tso cai rau koj los npaj cov ntaub ntawv tsim nyog rau kev tsim cov microcircuits.
- OpenLane yog ib pawg ntawm cov khoom siv rau kev hloov pauv ntawm RTL Circuit Court tsim ntawm daim ntawv thov tshwj xeeb chips (ASICs) rau hauv GDSII hom siv hauv cov chaw tsim khoom.
- XLS (Accelerated HW Synthesis) yog cov cuab yeej siv rau kev tsim cov ntaub ntawv tsim nrog cov khoom siv chip uas sib haum rau cov lus piav qhia qib siab ntawm cov haujlwm uas yuav tsum tau ua, tsim los ntawm kev tsim kho software.
- Cov txheej txheem rau kev sib dhos Bazel nrog kev txhawb nqa rau cov cuab yeej qhib (Yosys, Verilator, OpenROAD) rau kev ua haujlwm nrog cov lus piav qhia kho vajtse (Verilog, VHDL, Chisel, nMigen).
- OpenROAD yog lub moj khaum rau automating txoj kev loj hlob ntawm qhib qhov chaw microcircuits.
- Verible yog ib txheej ntawm cov cuab yeej rau kev txhim kho hauv Verilog lus, suav nrog kev sib cais, cov qauv tsim qauv thiab linter.
