how to determine the power planning?
1) IO to core distance: can place VDD and VSS is enough?
2) how many stripes should we place? the VDD& VSS stripe inside one set VDD/VSS stripes is determined by the spec of the metal rule?
3) how to know where to place which IOs?
4) what is a good strategy for high speed design?

2)the stripes width is determined by EM. we can calculate the width of the width by the foundry technics.
Wstripe_v=Itop/Jmetal
Wstripe_h=Ileft/Jmetal.

Added after 6 minutes:

) because the ring width can get ,so the IO to core distance must bigger than twice of it ??
