[SI-LIST] Split power Plane support for Hyperlynx


Hi gurus,

I would like to know ,Hyperlynx supports for Split Power planes from

Mentor's board station......

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.

Thanks & Regards,
