El I-SkyWater 130nm PDK yikiti yoyilo lwenkqubo yeCMOS evulekileyo eguqule ukufikelela kwimveliso yesekethe edibeneyo. Enkosi kwintsebenziswano phakathi kukaGoogle kunye neSkyWater, abaqulunqi ngoku banokuphonononga kwaye bazenzele iitshiphusi zabo ngaphandle kwesidingo selayisensi ebizayo. Kweli nqaku, sikuchazela Yonke into omawuyazi malunga ne-SkyWater PDK, ukusuka kufakelo ukuya kwizixhobo ezixhaswayo kunye nezenzo ezilungileyo.
Ukuba ngu iprojekti yomthombo ovulekileyoI-SkyWater PDK inikezela uluntu loyilo amandla okulinga kunye nokuphucula uyilo lwabo isoftware efikelelekayo kunye nezixhobo zehardware. Nangona ingekakulungeli ukuveliswa ngobuninzi, le khithi imele ithuba elikhethekileyo le uphuhliso kunye nokuqinisekiswa koyilo lwesekethe edibeneyo edibeneyo.
Yintoni i-SkyWater PDK?
I-SkyWater PDK yi inkqubo yoyilo lwekiti (PDK) isekelwe kwi-SkyWater Technology Foundry ye-130nm iteknoloji. Yasungulwa njengeprojekthi yomthombo ovulekileyo ngenjongo yokufikelela kwidemokhrasi kuyilo oludityanisiweyo lwesekethe.
Ngelixa le PDK ingajoliswanga ngoku kwimveliso yobuninzi, ifanelekile Ukuqinisekiswa koyilo kunye nokudalwa kweetshiphusi zovavanyo. I-Google kunye ne-SkyWater bayaqhubeka novavanyo lwangaphakathi kunye nokuqinisekiswa kwe-silicon yedatha ekhutshiweyo.
Izixhobo ezihambelana ne-SkyWater PDK
Enye yezona zinto zinomdla kakhulu ze-SkyWater PDK yinkxaso yokuphindaphinda Uyilo kunye nezixhobo zokulinganisa. Ezinye zezona zibalaseleyo zezi:
- umlingo: I-software yoyilo lwesekethe edibeneyo evumela ukudalwa kwezakhiwo, nangona ukusetyenziswa kwayo kunokuba nzima ngenxa ye-interface ye-manual.
- I-OpenLane: Ukuhamba koyilo oluzenzekelayo olusekwe kwisixhobo somthombo ovulekileyo oququzelela ukubekwa kunye nomzila weeseli eziqhelekileyo.
- Qflow: Isixhobo soyilo oluzenzekelayo esenza ukuhlanganiswa kwe-SkyWater 130nm, nangona ukuhambelana kwayo kuyingxenye.
- ngspice kunye neCadence Specter: Izifanisi ezimbini ezisetyenziswa ngokubanzi kwi ukuqinisekiswa kwesekethe.
Ngelixa ezinye izixhobo ezifana I-OpenLane ukuququzelela inkqubo yoyilo, ukudibanisa ne-SkyWater PDK kunokufuna umsebenzi owongezelelweyo kunye nohlengahlengiso lwesiko.
SkyWater PDK Architecture kunye neebhloko
I-SkyWater PDK ibandakanya iibhloko zoyilo ezahlukeneyo eququzelela ukuyilwa kweesekethe zesiko:
- Iiseli ze-I/O: Ingqokelela yeeseli kunye neeprimitives ezivumela igalelo kunye neringi zemveliso ukuba zakhiwe.
- Izithinteli zegalelo kunye nemveliso: Ngamandla okusebenzisa ahlukeneyo kunye neendlela zoqwalaselo.
- Reference generator: Isetyenziselwa ukunika ireferensi yombane kwezinye iibhloko zePDK.
Imingeni kunye neengqwalasela ekusebenziseni i-SkyWater PDK
Nangona i-SkyWater PDK sisixhobo esinamandla, siqinisekile Imida kunye nemingeni ukucingela:
- Ikhefu lokuFunda: Ezinye izixhobo zifuna ulwazi oluphambili kuyilo lwesekethe.
- Unyino kwimveliso: Okwangoku ayijoliswanga kwimveliso yobuninzi, kodwa ijolise ekuqinisekiseni nasekuvavanyweni.
- Ubukho bamaxwebhu:Nangona ilinyathelo elivulelekileyo, eminye imiba yobugcisa inokungabi namaxwebhu aneenkcukacha.
Nangona kunjalo, uluntu lomthombo ovulekileyo luphumeze uphuculo oluninzi kwaye luvelise izixhobo ezongezelelweyo ukwenza iPDK ibe lula ukuyisebenzisa. I-SkyWater PDK ibe yireferensi ephambili yovavanyo kunye nophuhliso loyilo lwesekethe edibeneyo. Ngaphandle kwemingeni yayo, inika ithuba elikhethekileyo lokuba abayili kunye nabaphandi basebenze ngezixhobo eziphambili ngaphandle kwezithintelo zepropathi enomgangatho ophezulu wokuqonda.
