Yemukati chip chimiro

1.1 System level

Iyo yese nharembozha, semuenzaniso, yakaoma yedunhu sisitimu inotamba mitambo, inofona, inoteerera mimhanzi, nezvimwewo. Yayo yemukati chimiro inoumbwa akati wandei semiconductor chips pamwe nevanopikisa, inductors, uye capacitors zvakabatanidzwa, zvinonzi the system level.(Ehe, nekuvandudza tekinoroji, tekinoroji yekugadzira system yese pane imwechete chip yave iripo kwemakore mazhinji - SoC tekinoroji)

1.2 Module level

Iyo yese system yakakamurwa kuita akawanda anoshanda modules imwe neimwe ine basa rayo.Vamwe vanotonga simba, vamwe vane basa rekutaurirana, mamwe ekuratidzira, mamwe eruzha, mamwe ezvese computing, zvichingodaro.Isu tinodaidza iyi iyo module level.Imwe neimwe yemamodule iyi imunda wakanakisa, chibereko chehungwaru husingaverengeki hwevanhu.

1.3 Kunyoresa Kutamisa Chikamu (RTL)

Imwe neimwe module inoenzanisirwa nedhijitari yedunhu module (iyo yakatsaurirwa kuita logic mashandiro uye kugadzirisa masaini emagetsi ese ari discrete zero uye mamwe), ayo anoverengera chikamu chikuru chese system.Iyo inoumbwa nemarejista uye musanganiswa logic maseketi.

Rejista idhizaini yedunhu inokwanisa kuchengetedza kwenguva pfupi kukosha kweiyo logic, uye inoda chiratidzo chewachi kudzora urefu hwenguva iyo kukosha kwelogic kunochengetwa.Mukuita, wachi inodiwa kuyera nguva yenguva uye dunhu rinoda chiratidzo chewachi kuronga hurongwa.Chiratidzo chewachi irectangular wave ine nguva yakagadzikana.Muchokwadi, sekondi imwe ndiyo chiyero chenguva, uye mudenderedzwa, rectangular wave inotenderera kune imwe denderedzwa, inova chiyero chenguva yenyika yavo.Zvikamu zvedunhu zvinoshanda zvinoenderana nechiyero chenguva ino uye vanozadzisa zvavanosungirwa.

Combinational logic musanganiswa weakawanda "AND, OR, uye NOT" magedhi epfungwa.

Iyo yakaoma inoshanda module inoumbwa neakawanda marejista uye musanganiswa wepfungwa.Chinhanho ichi chinodaidzwa kuti register transfer level.

1.4 Gedhi level

Iwo marejista ari muchikamu chekuendesa rejista anoumbwawo kana asina logic, achiipatsanura mukati, kana pasina logic, unosvika padanho regedhi (akaita semusuwo unovhara / unobvumira kupinda nekubuda kwemasaini emagetsi, saka. zita).

1.5 Transistor level

Kunyangwe iri dhijitari kana analog dunhu, pazasi pehierarchy ndiyo transistor level.Magedhi ese ane logic (uye, kana, asiri, ane kana asina, asina, akasiyana kana, akafanana kana, nezvimwewo) anoumbwa neakasarudzika transistors.Nokudaro dunhu rakabatanidzwa rakazara ne transistors uye waya dzinovabatanidza, kubva kune macroscopic kusvika kune microscopic, kusvika kune yakaderera.

Bipolar transistor (BJT) yainyanya kushandiswa mumazuva ekutanga uye yaiwanzozivikanwa se triode.Yakanga yakabatanidzwa kune resistor, magetsi, uye capacitor, iyo pachayo yakanga ine simba rekusimudzira chiratidzo.Sechivharo chekuvaka, chinogona kushandiswa kugadzira matunhu akasiyana-siyana senge switch, voltage/current source circuits, logic gate circuits dzataurwa pamusoro apa, mafirita, comparator, adder, and even integrators, kungotaura zvishoma.Denderedzwa akavakwa kubva kuBJTs anonzi TTL (Transistor-TransistorLogic) maseketi.

Asi kwakazouya simbi-oxide-semiconductor field-effect transistor (MOSFET), iyo yakatsvaira IC munda nemaitiro ayo emagetsi akanakisa uye mashandisirwo emagetsi ekupedzisira-akaderera.Kunze kwemaseketi eanalogue uko maBJT achine huvepo, ese maICs ave kuumbwa neMOS machubhu.Zvinokwanisikawo kuvaka zviuru zvemaseketi kubva mairi.Inogona zvakare kushandiswa kune zvakakosha zvedunhu zvikamu senge resistors uye capacitors nekuzvibatanidza zvakakodzera.

Sezvambotaurwa pamusoro apa, mukugadzirwa kweindasitiri chaiyo, kugadzirwa kwechip inzira yekugadzira zviuru zve transistors.Asi muchokwadi, kurongeka kwezvikamu kunodzoserwa shure, kutanga kubva kune yakaderera transistor uye kushanda kumusoro.

Mune mamwe mazwi, nekutevera kutevedzana kwe "transistor - chip - circuit board", tinopedzisira tave nechepakati chikamu chechigadzirwa chemagetsi - bhodhi redunhu.
