Google, ka tšebelisano-'moho le lik'hamphani tsa tlhahiso ea SkyWater Technology le Efabless, e qalile mohato o lumellang baetsi ba lisebelisoa tse bulehileng ho etsa li-chips tseo ba li hlahisang mahala. Boikitlaetso bona bo ikemiselitse ho khothaletsa nts'etsopele ea lisebelisoa tse bulehileng, ho fokotsa litšenyehelo tsa ho theha merero e bulehileng le ho nolofatsa tšebelisano le lifeme tsa tlhahiso. Ka lebaka la morero ona, mang kapa mang a ka qala ho iketsetsa li-chips tsa bona ntle le ho tšaba litšenyehelo tse phahameng tsa ho hlahisa li-prototype tsa pele. Litefiso tsohle tsa tlhahiso, ho paka le ho romella li lefelloa ke Google.
Likopo tsa ho kenyelletsoa lenaneong la tlhahiso ea mahala li ka romelloa hang ka mor'a likhoeli tse ling le tse ling tse peli. Slot e haufinyane e tla koaloa ka la 8 Phuptjane, 'me li-chips tse khonneng ho kena ho eona li tla be li lokile ka la 30 Phato ebe li romelloa ho bangoli ka la 18 Mphalane. Ho tsoa likopong tse rometsoeng, ho khethoa merero ea 40 (haeba likopo tse rometsoeng li le ka tlase ho 40, joale bohle ba fetisitseng tlhahlobo e nepahetseng ba tla kenngoa tlhahiso). Ho ipapisitsoe le liphetho tsa tlhahiso, mohlahlami o tla amohela li-chips tse 50 le liboto tse 5 tse nang le li-chips tse kentsoeng.
Likopo li amoheloa feela ho tsoa mererong e abuoang ka botlalo tlas'a laesense e bulehileng, e sa imetsoeng ke litumellano tsa ho se senole (li-NDAs) le ho se behe moeli oa tšebeliso ea lihlahisoa tsa bona. Lintlha tsa tlhahiso li tlameha ho fetisetsoa ka mokhoa oa GDSII, ho fetisa tlhahlobo e fanoeng le ho hlahisoa hape ho tsoa ho lifaele tsa moralo oa mohloli (ke hore, fana ka morero oa mohloli o bulehileng, empa u ke ke ua khona ho fana ka moralo oa thepa bakeng sa tlhahiso).
Ho nolofatsa nts'etsopele ea chip e bulehileng, lisebelisoa tse latelang tsa mohloli o bulehileng lia fumaneha:
- SkyWater PDK (Process Design Kit), sesebelisoa sa lisebelisoa se hlalosang mokhoa oa theknoloji oa 130nm (SKY130) o sebelisoang setsing sa SkyWater mme o u lumella ho lokisetsa lifaele tsa moralo tse hlokahalang bakeng sa tlhahiso ea microcircuits.
- OpenLane ke sehlopha sa likarolo tsa phetoho e ikemetseng ea moralo oa potoloho oa RTL oa li-chips tse khethehileng tsa kopo (ASICs) ho sebopeho sa GDSII se sebelisoang lifemeng tsa chip.
- XLS (Accelerated HW Synthesis) ke sesebelisoa sa ho kopanya lifaele tsa moralo ka lisebelisoa tsa chip tse tsamaellanang le tlhaloso e fanoeng ea boemo bo holimo ea ts'ebetso e hlokahalang, e entsoeng ka mokhoa oa ntlafatso ea software.
- Lethathamo la melao bakeng sa sistimi ea kopano ea Bazel e nang le ts'ehetso ea lisebelisoa tse bulehileng (Yosys, Verilator, OpenROAD) bakeng sa ho sebetsa ka lipuo tsa litlhaloso tsa Hardware (Verilog, VHDL, Chisel, nMigen).
- OpenROAD ke moralo oa ho iketsetsa ts'ebetso ea nts'etsopele ea li-microcircuits tse bulehileng.
- Verible ke sehlopha sa lisebelisoa bakeng sa nts'etsopele ea puo ea Verilog, ho kenyeletsoa mohlahlobi, mokhoa oa ho fometa setaele le linter.
