Board Stackup: Signal-1 Etch Layer-1 Signal-2 Etch Layer-2 Power-1 To Power-7 Etch Layer-3 Signal-3 Etch Layer-4 Signal-4 Etch Layer-5 Power-8 To Power-14 Etch Layer-6 Signal-5 Etch Layer-7 Signal-6 Etch Layer-8 Power-15 To Power-21 Etch Layer-9 Power-22 To Power-24 Etch Layer-10 Power-25 To Power-26 Etch Layer-11 Power-27 To Power-29 Etch Layer-12 Signal-7 Etch Layer-13 Signal-8 Etch Layer-14 Power-30 To Power-32 Etch Layer-15 Signal-9 Etch Layer-16 Signal-10 Etch Layer-17 Power-33 To Power-35 Etch Layer-18 Signal-11 Etch Layer-19 Signal-12 Etch Layer-20 Actually in our design, Layers 3,6,9,10,11,12,15,18 are power planes. Each power plane includes some 7 different power nets and so totally 35power layers are available in the design.......... When i translate the database to Hyperlynx, the tool treats all the 35 power planes as solid planes and the prepreg and the core material thickness is added between each power layers,so total board thickness increased to 255mils,but the actual board thickness is 96 mils. So any of you know how to modify the Edit--> Stackup for split planes with one single plane.
