層以上板(優(yōu)點(diǎn)是：防干擾輻射)，選擇內(nèi)電層走線，走不開選擇平面層，禁止從地或電源層走線(原因：會(huì)分割電源層，產(chǎn)生寄生效應(yīng))。多電源系統(tǒng)的布線：如FPGA+DSP系統(tǒng)做6層板，一般至少會(huì)有3.3V+1.2V+1.8V+5V。3V一般是主電源，直接鋪電源層，通過過孔很容易布通全局電源網(wǎng)絡(luò)。5V一般可能是電源輸入，只需要在一小塊區(qū)域內(nèi)鋪銅。且盡量粗(你問我該多粗——能多粗就多粗，越粗越好)1.2V和1.8V是內(nèi)核電源(如果直接采用線連的方式會(huì)在面臨BGA器件時(shí)遇到很大困難)，布局時(shí)盡量將1.2V與1.8V分開，并讓1.2V或1.8V內(nèi)相連的元件布局在緊湊的區(qū)域，使用銅皮的方式連接，如下圖：總之，因?yàn)殡娫淳W(wǎng)絡(luò)遍布整個(gè)PCB，如果采用走線的方式會(huì)很復(fù)雜而且會(huì)繞很遠(yuǎn)，使用鋪銅皮的方法是一種很好的選擇!鄰層之間走線采用交叉方式：既可減少并行導(dǎo)線之間的電磁干擾(高中學(xué)的哦)，又方便走線(參考資料1)。
