1. Ndezvipi zvinhu izvo zvinofanirwa iyo Dunhu reCocort Bhodhi Debug Start kubva?
Sekusvika kwenzvimbo dzemitambo zvine hanya, tanga waziva zvinhu zvitatu muhurongwa:
1) Simbisa kuti zvese zvesimba zvinokosheswa zvinosangana nezvinodiwa zvekugadzira. Mamwe masisitimu ane akawanda masimba emagetsi anogona kuda zvimwe zvakatsanangurwa zvekuraira uye nekumhanya kwezvinhu zvisina simba.
2) Simbisa kuti yese yeClock chiratidzo mafambiro arikushanda nemazvo uye hapana matambudziko asiri monotonic pamiratidzo yemiratidzo.
3) Simbisa kana iyo seti siginecha inosangana nezvinodiwa zvekufungidzira.
Kana izvi zvakajairika, chip chinofanira kutumira kunze kwekutanga kutenderera (kutenderera) chiratidzo. Tevere, debug maererano neyekushanda nheyo yehurongwa uye iyo bhazi protocol.
2. Panyaya yedunhu rakatemwa size, kana mabasa mazhinji anofanirwa kuganhurirwa mukugadzirwa, uye izvi zvingaitwe zvakanyanyisa, ndapota svitsa hunyanzvi
Paunenge uchigadzira yakakwira-kumhanya uye yakakwira-density pcss, crosstalk kupindira Heano mashoma mashoma ekuona:
1) Dzora kuenderera mberi uye kufanana kwehunhu husina simba rekusvibiswa kwe wiring.
Saizi yeiyo trace kupatsanuka. Zvinowanzoonekwa kuti kupatsanurwa kuri kaviri mutsara upamhi. Izvo zvinokwanisika kuziva pesvedzero yekuteedzera kupatsanurana nguva uye kutendeka kwemiratidzo kuburikidza nekufungidzira, uye kuwana mashoma anokanganiswa. Mhedzisiro yemasaini akasiyana chips inogona kunge yakasiyana.
2) Sarudza yakakodzera yekubvisa nzira.
Ngwarira zviyero zviviri zvakafanana newiring nhungamiro yemoto mumwechete, kunyangwe paine maunike anowedzera mumwe nemumwe, nekuti rudzi urwu rwe crosstalk yakakura kupfuura iyo yewava wiring yepakutanga pane imwe danga.
Shandisa mapofu / kuvigwa vias kuti uwedzere nzvimbo yekutevera. Asi mari yekugadzira yePCB Board ichawedzera. Izvo zvakaoma chaizvo kuwana zvakafanana kufanana uye urefu hwakaenzana mukuita chaiko, asi zvichiripo kuti zviite kudaro.
Mukuwedzera, kusiyanisa kusiyanisa uye zvakajairika mode kubviswa kunogona kuchengeterwa kuderedza kukanganisika pakutendeuka nenguva.
3. Iko kusefa kuAnalog Power Kuwanikwa kunowanzo shandisa dunhu reLC. Asi nei mhedzisiro yekutsvedza yeLC yakaipa kupfuura rc dzimwe nguva?
Kuenzanisa kweLC uye RC faira yekuisa inofanirwa kufunga kana iyo frequency bhendi kuti isheyo uye sarudzo yekunyengerera yakakodzera. Nekuti kureverera kweiyo inductor (maitiro) ane hukama nekukosha kwekunyepedzera uye frequency. Kana ruzha rwekuwedzera kwesimba remagetsi rakadzika, uye kukosha kwekunyepedzera hakuna kuwanda zvakakwana, iyo faira rekushandisa inogona kunge isiri yakanaka se rc.
Nekudaro, mutengo wekushandisa rc kusefa ndewekuti iyo inodzvinyirira inochengetedza simba uye ine kugona kwakashata, uye teerera kune simba iro rinodzora simba rakasarudzwa rinogona kumira.
