14 Layaer PCB (88.5 mils Thick)

Engineer asked Mar 24,2023

I would like to improve the PDN and would prefer to have Power/GND planes closer to TOP/BOT. Please help me in rearranging the S/P/G assignments to imrove:

    - PDN (with P/G closer & Thin Dielectric in between), Closer to Top/Bottom layers

    - Must improve EMI

    - Better Signal Integrity

    -  Zo = 50 Ohms, Zdiff ~ 100 Ohms

    - Eight Signals Layers & rest P/G

    - Assume FR4
