Cadence PCB實(shí)用培訓(xùn) 

一、培訓(xùn)目標(biāo)
高速PCB設(shè)計(jì)的潮流已經(jīng)滾滾而來(lái)，如何預(yù)防PCB板上出現(xiàn)的信號(hào)反射、串?dāng)_、電源/地平面干擾、時(shí)序匹配以及電磁兼容性等一系列新問(wèn)題好象突然間擋在了您的面前。如何應(yīng)對(duì)新的設(shè)計(jì)挑戰(zhàn)？Cadence培訓(xùn)高級(jí)班將首先讓您了解這些問(wèn)題產(chǎn)生的機(jī)理，并掌握其解決方法；然后講解并上機(jī)練習(xí)Cadence的高速 PCB設(shè)計(jì)與仿真工具SPECCTRAQuest的使用。使您在硬件設(shè)計(jì)過(guò)程中，能夠達(dá)到“設(shè)計(jì)即正確”的目的。
二、培訓(xùn)內(nèi)容：
