NeChishanu (Nyamavhuvhu 12), nguva yemuno, US Department of Commerce's Bureau of Industry and Security (BIS) yakaburitsa muFederal Register mutemo mutsva wekugumisira wekurambidza kunze kwenyika unorambidza.dhizaini yeGAAFET (Full Gate Field Effect Transistor). ) EDA/ECAD software inodiwa kune zvimiro zvakabatanidzwa maseketi; Ultra-wide bandgap semiconductor zvinhu zvinomiririrwa nedhaimondi uye gallium oxide; matekinoroji mana akadai sekumanikidza kuwana combustion (PGC) anoshandiswa muinjini dzegasi turbine kuita zvidzoreso zvitsva zvekunze, zuva rinoshanda rekurambidzwa kwanhasi (Nyamavhuvhu 15).
Pakati petekinoroji ina, EDA ndiyo inonyanya kubata maziso, inodudzirwa nemusika sezvimwe zvirambidzo kuChina chip indasitiri neUnited States mushure me "Chip neScience Act", iyo inobata zvakananga makambani epamba anogadzira 3nm uye yakanyanya kufambira mberi. chip zvigadzirwa.Nekudaro, 3-nanometer dhizaini haiwanzo kushandiswa muChina parizvino, uye mhedzisiro yayo yenguva pfupi ishoma.
Pamusoro peiyo 3nm maitiro, 800V nekukurumidza kuchaja inogona kukanganiswa
EDA (Electronics Dhizaini otomatiki) ndeyemagetsi dhizaini otomatiki, inova chikamu chakakosha uye chakakosha che chip IC (yakabatanidzwa redunhu) dhizaini. Iyo ndeyekumusoro indasitiri yekugadzira chip, inovhara ese maitiro akadai seyakabatanidzwa redunhu dhizaini, wiring, verification uye simulation.EDA inonzi "amai vemachipisi" muindasitiri.
Tianfeng International Research Report yakaratidza kuti kana kugadzirwa kwechipi kuchifananidzwa nekuvaka chivakwa, IC dhizaini idhizaini yedhizaini, uye EDA software chishandiso chekugadzira chekudhirowa, asi EDA software yakanyanya kuomarara kupfuura mapuratifomu ekugadzira.
ECAD (Electronic Computer Aided Design software) ine nzvimbo yakafara kupfuura EDA, uye kurambidzwa kunoreva kuti software yese ine hukama yakavharwa.Zvinoenderana neUS Department of Commerce, ECAD ikirasi yezvishandiso zvesoftware zvinoshandiswa kugadzira, kuongorora, kugadzirisa uye kuona mashandiro edunhu rakasanganiswa kana rakadhindwa redunhu.Inoshandiswa kugadzira maseketi akaomesesa akabatanidzwa mune akasiyana maapplication mumauto, aerospace, uye maindasitiri ekudzivirira.
GAAFET transistor tekinoroji tekinoroji yepamberi kana ichienzaniswa neFinFET transistors (fin field effect transistors), FinFET tekinoroji inogona kusvika ku3 nanometers, nepo GAAFET ichikwanisa kuwana 2 nanometers.
Iyi ndiyo yechitatu kudzora kunze kwenyika kwakatangwa neUnited States kurwisa China mumunda weEDA.Yekutanga yaipesana neZTE muna 2018 uye yechipiri yaipesana neHuawei muna 2019.Pamusoro pemagetsi evatengi akadai seApple nharembozha nemakomputa, machipi anoshandisa yakanyanya kugadzirwa maitiro pamusika ese machipisi ane simba repamusoro rekombuta, senge maGPU anoshandiswa kuhungwaru hwekugadzira, uye maseva machipisi anoshandiswa munzvimbo dzedata uye Cloud computing. .
Vamwe vanogadzira chip vakati iyo yenguva pfupi mhedzisiro yeiyi chiyero chekudzora ishoma, nekuti 3-nanometer magadzirirwo haawanzo kushandiswa muChina. Mamwe machipisi eAI uye maGPU machipi anoshandisa 7-nanometers, nepo maTV, set-yepamusoro mabhokisi, uye mota-giredhi machipisi anowanzo 28 nm. nanometer kana 16 nanometer.Vamwe vacherechedzi veindasitiri vanotenda kuti United States inoda kuita kuti nyika yeChinese ive isina maturusi ekugadzira machipisi epamusoro-soro e3 nanometers uye pazasi, uye dhizaini inonamira pa5 nanometers, uye kugadzira kwakanamira pa7 nanometers.Zvadaro, chinhambwe chiri pakati peChina neUnited States mukombuta yekumhanyisa, yekugadzira AI, nezvimwewo ichawedzerwa.
Mune maonero emunhu chip, chikonzero chikuru nei United States ichidzvanya EDA kudzora huwandu hwekugadzira hwemachipisi epamba.
Pamusoro peiyo EDA software panguva ino, maviri semiconductor zvinhu zvinosanganisirwa: gallium oxide (Ga2O3) uye madhaimani substrates, ese ari ekupedzisira-wide bandgap semiconductor zvinhu.Zvishandiso zvakadaro zvinotarisirwa kushanda pasi pemamiriro akaomarara, senge yakakwira voltages kana tembiricha yakakwira.
Zvishandiso izvi zvichiri mukusimudzira uye hazvina kugadzirwa zvakanyanya, uye tekinoroji inonyanya kutariswa muJapan neUnited States.Nekudaro, machipisi akagadzirwa nezvinhu izvi anozonyanya kukodzera kune akawanda maindasitiri nharaunda senge simba idzva, grid rekuchengetedza simba, kutaurirana, nezvimwe, uye nekudaro inove inonzwisisika uye yakakosha.
Tichitora mota nyowani dzemagetsi semuenzaniso, parizvino, makambani emotokari emagetsi matsva akadai seXiaopeng Motors, BYD, Li Auto, uye BAIC Jihu akatoisa tekinoroji yekuchaja 800V, uye ichagadzirwa-zhinji gore rino.Zvishandiso zvemagetsi zvakagadzirwa negallium oxide zvinhu zvinogona kushandiswa mune idzi kukurumidza kuchaja matekinoroji.
Dzimba EDA "kubudirira" mukana
“Ukagadzira chigadzirwa che5-nanometer chip woshandisa software yepamusoro yeEDA, mutengo unokwanisa kudzorwa nemadhora anosvika miriyoni makumi mana emadhora ekuAmerica, asi pasina EDA software inotsigirwa, mutengo wekugadzira 5-nanometer chip unogona kunge wakakwirisa. 7.7 mabhiriyoni emadhora ekuAmerica. Dhora rekuAmerica riri pedyo nepakati penguva dzinosvika mazana maviri. " Munhu akakodzera anotarisira kambani yemumba yeCAD (computer-aid design) software yakaverenga account.
Parizvino, huwandu hwemusika wepasi rose weindasitiri yeEDA hwakanyanya. Hofori nhatu dzeEDA Synopsys (Synopsys), Cadence (Kedence Electronics), uye Mentor Graphics (Mentor International, yakawanikwa neSiemens kuGermany muna 2016) inogara zvakasimba kupfuura 70% yemusika wepasi rose. mugove wemusika, uye inogona kupa yakakwana EDA zvishandiso, inovhara iyo yese maitiro kana yakawanda yemaitiro ekubatanidza edunhu dhizaini nekugadzira.
Iwo makambani matatu ane hunhu hwawo mune zvigadzirwa, uye kutarisa uye zvakanakira zveIP (intellectual property) zvakatosiyana. Zvigadzirwa zvavo zvine chikamu chemusika che85% muChina.Iyo 3-nanometer GAAFET architecture process tekinoroji iyo Samsung ichangopaza muna Chikumi gore rino yakapedzwa nerubatsiro rweSynopsys neCadence.
Makambani echipiri-tier anomiririrwa ne ANSYS, Silvaco, Aldec Inc, Huada Jiutian, etc. Vane nzira yose muminda chaiyo uye vanonyanya kufambira mberi mune teknolojia muminda yemunharaunda.Makambani ari muchikamu chechitatu anosanganisira Altium, Concept Engineering, Introduction Electronics, Guangliwei, Sierxin, DownStream Technologies, etc. Kurongeka kweEDA kunonyanya kuenderana nematurusi epfungwa, uye pane kushayikwa kwezvigadzirwa zvakakwana-zvakakwana muminda chaiyo.
Mazhinji edzimba chip dhizaini makambani achiri kushandisa kunze kwenyika EDA maindasitiri software kugadzira machipisi. Muna 1993, Huada Jiutian akaburitsa yekutanga EDA software - Panda ICCAD system, iyo yakawana budiriro mudzimba EDA kubva 0 kusvika 1.Muna 2020, mumusika weChina weEDA, maererano nehuwandu hwemari, Huada Jiutian ari pachinhanho chechina.
Musi waChikunguru 29, Huada Jiutian akasvika zviri pamutemo paKukura Kwemabhizinesi Musika, nekuwedzera kwe126% pazuva rekutanga rekunyora, uye kukosha kwayo kwemusika kwakapfuura mabhiriyoni makumi mana emayuan.Huada Jiutian akataura mune tarisiro kuti mazhinji edhijitari yedunhu dhizaini EDA zvigadzirwa zvinogona kutsigira iyo 5-nanometer maitiro; Gelun Electronics yakataura mumushumo wayo wepagore kuti mamwe maturusi anogona kutsigira 7-nanometer, 5-nanometer, uye 3-nanometer maitiro.
Mari yaHuada Jiutian muna 2021 i580 miriyoni yuan, uye mari yeGailun Electronics isingasviki mazana maviri emamiriyoni yuan.Nhamba yekutanga yepasi rose ine mari inosvika mabhiriyoni makumi maviri nematanhatu eyuan uye purofiti inodarika mabhiriyoni mashanu emayuan.
Tianfeng International Research Report yakaratidza kuti kugarisana kwakakosha. Kune anosvika makumi mana madiki-sectors muEDA tool cheni. Hofori nhatu idzi dzakawana kufukidzwa kweiyo indasitiri yese cheni, nepo mutungamiri wepamba Huada Jiutian parizvino ane chiyero chekuvhara chingangoita makumi mana%. Zvimwe Zvigadzirwa zvevagadziri veEDA vepamba zvinonyanya kunongedzera maturusi.
Zvinoenderana nenhamba, kune angangoita zana ekugadzira maturusi makambani muChina.EDA yakakamurwa kuita analog chip dhizaini maturusi uye dijitari chip dhizaini maturusi.Mamwe makambani epamba akagadzirisa maitiro ese ekugadzira analog chips.Zvishandiso zvekugadzira zvemadhijitari machipisi zvakanyanya kuoma. Inenge 120 "maturusi ekunongedza" anobatanidzwa mukugadzira maitiro, uye kutsvagisa nekusimudzira kunoitwa pane imwe neimwe point tool.
Pane maonero ekuti kune midziyo yeUnited States, nzira chete yekuvandudza chiyero cheEDA software ndeyekukurumidza kuvandudza mwero weEDA software, uye mabhizinesi epamba anofanira kubatana, uye kunyange Huawei HiSilicon nemayunivhesiti epamba anofanira kutora chikamu. mukugadzira mibatanidzwa yekusimudzira pamwe chete.Nekuwedzera kuri kuda kwemachipisi epamba, EDA yemumba haina mikana mumusika wemutengi.
