Dab tsi yog qhov sib txawv ntawm kev thaiv thiab tsis thaiv cov lus hauv verilog? A thaiv nqe lus yuav tsis thaiv kev ua tiav ntawm nqe lus uas nyob rau hauv parallel thaiv , txhais tau tias nws yuav ua raws li lub sijhawm Tsis thaiv assignment tso cai teem sij hawm ntawm txoj hauj lwm uas tau ua nyob rau hauv sequential thaiv.
Khaws qhov no hauv kev pom, dab tsi yog thaiv thiab tsis thaiv hauv Verilog?
Zoo, "=" yog thaiv assignment thiab "<=" yog tsis thaiv txoj haujlwm. "=" executes code sequentially hauv pib / kawg, whereas tsis thaiv " < = " executes nyob rau hauv parallel. Tom qab tag nrho, koj tuaj yeem ua thaiv assignments nrog assign nqe lus sab nraum ib txwm thaiv , thiab tag nrho cov khiav nyob rau hauv parallel.
Ib yam li ntawd, qhov txawv ntawm asynchronous thiab tsis thaiv yog dab tsi? Ib asynchronous hu thov kev hloov pauv uas yuav ua tiav tag nrho (tag nrho) tab sis yuav ua tiav nyob rau qee lub sijhawm yav tom ntej. Tsis yog - thaiv : Cov haujlwm no yuav tsis tos thaum nyob hauv pawg. Synchronous txhais tau tias tshwm sim tib lub sijhawm. Asynchronous txhais tau tias tsis tshwm sim tib lub sijhawm.
Kuj kom paub, dab tsi yog thaiv hauv Verilog?
A thaiv txoj haujlwm tau txais nws lub npe vim a thaiv txoj haujlwm yuav tsum ntsuas RHS cov lus sib cav thiab ua tiav txoj haujlwm yam tsis muaj kev cuam tshuam los ntawm lwm yam Verilog nqe lus. Txoj haujlwm tau hais rau " thaiv "lwm txoj hauj lwm kom txog thaum txoj hauj lwm tam sim no tau ua tiav.
Kev ua haujlwm thaiv kev thaiv yog dab tsi?
Thaiv hais txog kev ua haujlwm uas thaiv txuas ntxiv mus txog qhov ntawd kev ua haujlwm ua tiav. Hauv qhov piv txwv muab, localStorage yog a thaiv kev ua haujlwm raws li nws stalls execution nyeem.
