Ntoa ea bareki e qobella baetsi ba konteraka ba semiconductor ho atamela haufi le baqapi. Khetho e le 'ngoe ea ho lumella bareki ba tsoang lefats'eng lohle ho rua molemo ho lisebelisoa tsa EDA tse tiisitsoeng ka liphetoho tsohle tsa morao-rao ke ho kenya litšebeletso marung a sechaba. Haufinyane tjena, katleho ea mokhoa ona e ile ea bontšoa ke ts'ebeletso ea ho lekola topology ea moralo oa chip, e kentsoeng sethaleng sa Microsoft Azure ke TSMC. Tharollo e ipapisitse le software ea mehleng ea Mentor Graphics 'Caliber nmDRC, ka April 2017 ke Siemens ea Jeremane.
How ho AMD, tlhahlobo e felletseng ea (ea 'mele) topology Nalane ea k'hamphani, 7nm Vega 20 GPU e nang le li-transistors tse limilione tse likete tse 13,2 e phethetse moralo ka lihora tse 10 feela. Phallo ea bobeli e ile ea nka hora hape. Ho feta tse peli ka lihora tse 19 tsa tlhahlobo lerung ke litholoana tse ntle haholo, AMD e itšepa. Sena se paka katleho ea mokhoa ona mme se bula menyetla e mecha bakeng sa baqapi: lihlahisoa tse ncha li tla khona ho hlaha 'marakeng ka potlako le ka ts'ebetsong e ntle.
Hoa thahasellisa ho hlokomela hore AMD Vega 20 GPU e ile ea lekoa sethaleng se hole ho li-processor tsa AMD EPYC 7000. Software ea Caliber nmDRC e ile ea sebelisoa ho li-cores tse 4410 kapa mecheng e 69 ea sebele (e nang le bandwidth e phahameng ka ho fetisisa ea memori). Bakeng sa mosebetsi o moholo oa memori joalo ka ho hlahloba topology ea processor, sena se bohlokoa haholo.
Baetsi ba software ba Caliber nmDRC le bona ba kentse letsoho katlehong ea khoebo. Software e ntlafalitsoeng e hloka 50% ea memori e tlase ho etsa mesebetsi e tšoanang ea netefatso ea topology. Sethala sa AMD sa EPYC, k'hamphani e re, e fana ka li-bandwidth tse 33% ho feta linyehelo tsa Intel. Haholo-holo, ts'ebeletso ea Azure, "memory subsystem" e sebetsa ka lebelo la ho fihla ho 263 GB / s, 'me mechini e fumanehang ea HB-class e fana ka 80% ho feta lipolanete tsa maru tse hlolisanang.
