soc power plan

Hi,
I am using soc encounter now, and I want to know how to power plan in hierachary
design. My design is soc chip including many modules,So I patition the design first
and place&route every block. I want to whether I should do power ring,power stripe,and follow pins for every block, and how to connect them in top level.
what is the hierarchy power plan flow?
thanks a lot!

two options:

1. plan the power at top level before partition
2. plan the power for every partition and make the power stripes as a power pin. And connect those power pins at top level
