nett list

electronic design mein, ack netalist ack electronic circuit kii connectivity kaa vivaran haye. apane sabse saral roop mein, ack nett list mein ack circuit mein electronic ghatakon kii ack soochi aur una nodes kii ack soochi hoti haye jinase way judey hotey hain. ack network (nett) dou yaa dou seey adhik aapas mein judey ghatakon kaa sangrah haye.
netalist kii sanrachana, jatilata aur pratinidhitva kaafee bhinn hoe sakate hain, lekin pratyek netalist kaa mool uddeshya sampark jaankaari denaa haye. netalist aamtaur parr udaaharan, nodes aur shayed shamil ghatakon kii kuchh visheshtaon key alawa kuchh bhee pradaan naheen karate hain. yadi way isase bahut adhik vyakt karate hain, tou unhein aamtaur parr ack hardware vivaran bhasha maanaa jaataa haye jaise kii verilogue yaa vhdl, yaa kaee bhaashaon mein seey ack vishesh roop seey simulator yaa hardware compiler (jaise kii spice analogue simulation netalist) key liye input key liye design kiya gayaa haye.
netalist key prakaar.
nett list iss prakaar hoe sakati haih
ack soochi kii samagri aur sanrachana.
adhikansh netalist mein yaa tou upayog kiye gaye bhaagon yaa upkaranon kaa vivaran hotaa haye yaa unakaa ullekh kiya jaataa haye. pratyek baar jaba ack bhaag kaa upayog ack soochi mein kiya jaataa haye, tou ise "udaaharan" kahaa jaataa haye.
yeye vivaran aamtaur parr una connections koo soochibaddh karenge joe usa prakaar key upkaran seey banaae jaate hain, aur usa upkaran key kuchh buniyaadi guna. inn connection binduon koo kaee anya naamon key beach "terminal" yaa "pinn" kahaa jaataa haye.
ack "udaaharan" ack mosfet transister yaa ack dwidhruvi junction transister seey laker ack pratirodhak, ack sandharitra yaa ack ekikrit paripath chip taka kuchh bhee hoe sakata haye.
udaharanon mein "terminal" hotey hain. vacuum cleaner key mamle mein, yeye terminal plug mein teen dhaatu key prong honge. pratyek terminal kaa ack naam hotaa haye, aur vacuum cleaner udaaharan koo jaari rakhane mein, way "tatasth", "jeevit" aur "ground" hoe sakate hain. aamtaur parr, pratyek udaaharan kaa ack anootha naam hoga, taaki yadi aapke paas vacuum cleaner key dou udaaharan hain, tou ack "wack 1" aur doosara "wack 2" hoe sakata haye. unake naamon key alawa, way anyatha samaan hoe sakate hain.
network (jaal) way taar hain joe paripath mein cheejon koo ack saath jodate hain. kissy design mein jaal key saath judee koee vishesh visheshataaen hoe sakati hain yaa naheen bhee hoe sakati hain, joe usa vishesh bhasha parr nirbhar karati haye jisamen jaal soochi likhi gaee haye, aur usa bhasha kii visheshataaen.
udaaharan adharit netalist aamtaur parr ack design mein upayog kiye jaane vaale udaharanon kii soochi pradaan karati haye.
pratyek udaaharan key saath, yaa tou shuddh naamon kii ack krambaddh soochi pradaan kii jaati haye, yaa jode kii ack soochi pradaan kii jaati haye, ack udaaharan port naam kii, usa shuddh naam key saath jisase vaha port judaa huaa haye. iss tarah key vivaran mein, jaal kii soochi koo connection soochiyon seey ekatra kiya jaa sakata haye, aur jaal key saath vishesh visheshtaon koo jodane key liye koee jagah naheen haye. masala udaaharan-adharit netalist kaa ack udaaharan haye.
nett-adharit netalist aamtaur parr sabhi udaharanon aur unaki visheshtaon kaa varnan karate hain, phir pratyek nett kaa varnan karate hain, aur kahate hain kii way pratyek udaaharan parr kiss port seey judey hain. yeh visheshtaon koo jaal key saath judey rahane kii anumati detaa haye.
ediff shayed nett-adharit netalist mein sabse prasiddh haye.
padanukram.
badey designs mein, design koo tukadon mein vibhajit karna ack aam pratha haye, pratyek tukada ack "paribhasha" bunn jaataa haye jise design mein udaaharan key roop mein upayog kiya jaa sakata haye. vacuum cleaner saadrishya mein, kissy key paas apane bandargaahon key saath vacuum cleaner paribhasha hoe sakati haye, lekin abb iss paribhasha mein machine key aantarik ghatakon aur way kaise judate hain (motor, switch, aadi) kaa puuraa vivaran bhee shamil hoga.), jaise ack taar rekhaachitra kartaa haye.
ack paribhasha jisamen koee udaaharan shamil naheen haye, usey "adim" (yaa "patta", yaa anya naam) kahaa jaataa haye; jabaki ack paribhasha jisamen udaaharan shamil hain, "padaanukramit" haye.
ack "mudaa huaa" padanukram ack ekal paribhasha koo kaee baar udaharanon dwara prastut karane kii anumati detaa haye. ack "unfolded" padanukram padanukram mein ack seey adhik baar ack paribhasha kaa upayog karane kii anumati naheen detaa haye.
mudey hue padanukram behad saghan hoe sakate hain. kuchh hii udaharanon kii ack chhoti soochi bahut badee sankhya mein udaharanon key saath designs kaa varnan curr sakati haye. udaaharan key liye, maan leejiye kii paribhasha a ack smriti koshika kii tarah ack saral adim haye. phir maan leejiye kii paribhasha b mein a key 32 udaaharan hain; c mein b key 32 udaaharan hain; d mein c key 32 udaaharan hain; aur e mein d key 32 udaaharan hain. design mein abb 5 paribhaashaaen (aeye seey ee) aur 128 udaaharan hain. phir bhee, ee ack aise paripath kaa varnan kartaa haye jisamen ack million seey adhik smriti koshikaaen hoti hain.
prakat hoe rhaa haye.
ack "sapaat" design mein, kewal adim hii tatkaal hotey hain. padaanukramit designs koo pratyek baar upayog kii jaane vaali paribhasha kii ack naee prati (ack nae naam key saath) banaakar punaraavarti roop seey "visfot" ("chapata") kiya jaa sakata haye. yadi design atyadhik modd diyaa gayaa haye, tou ise iss tarah seey vistaarit karane seey bahut badaa netalist databases hoga, lekin padanukram nirbhartaon koo sanrakshit kartaa haye. ack padaanukramit soochi koo dekhate hue, mool paribhasha seey ack adim udaaharan taka key maarg mein udaaharan naamon kii soochi usa adim key liye ekal advitiya maarg koo nirdisht karati haye. pratyek adim key liye maarg, ack saath liya gayaa, ack badee lekin sapaat soochi shamil haye joe bilkul compact padaanukramit sanskaran key barabar haye.
backnotation.
backenotation vaha detta haye jise padaanukramit netalist mein jodaa jaa sakata haye. aamtaur parr unhein nett list seey alag rakhaa jaataa haye, kyonki detta key aise kaee vaikalpik seton koo ack hii nett list mein lagu kiya jaa sakata haye. yeye detta ack bhautik design seey nikaale gaye hoe sakate hain, aur adhik sateek anukaran key liye atirikt jaankaari pradaan curr sakate hain. aamtaur parr detta ack padaanukramit path aur usa adim yaa paraspar sambandh key kaaran aar. see. deree key moolyon koo khojane key liye detta key ack tukade seey banaa hotaa haye.
viraasat.
aksar netalist mein upayog kii jaane vaali ack anya avadharana viraasat kii haye. maan leejiye kii ack sandharitra kii paribhasha mein "capacitance" naamak ack sambaddh visheshta haye, joe usee naam kii bhautik sampatti key anuroop haye, jiska default moolya "100 pee. aff" (100 picopharad) haye. iss sandharitra key pratyek udaaharan mein bhee aisee visheshta hoe sakati haye, kewal sandharitra key ack alag moolya key saath. aur anya udaaharan kissy bhee kshamata koo bilkul bhee sambaddh naheen curr sakate hain. usa mamle mein jahaan kissy udaaharan key liye koee capacitance nirdisht naheen haye, udaaharan apani paribhasha seey 100 pee. aff. moolya koo "viraasat mein" dega. nirdisht moolya paribhasha parr moolya koo "override" karega. yadi paribhasha key samaan hii bahut saaree visheshataaen samaapt hoe jaati hain, tou bahut saaree jaankaari "viraasat mein millie" hoe sakati haye, aur ise nett list mein anaavashyak roop seey nirdisht naheen kiya jaanaa chaahiye, jisase jagah kii bachat hoti haye, aur donon machines aur logon dwara design koo padhana aasaan hoe jaataa haye.
