Power Bus distribution
Hi,
I have some doubt on the power busing distribution, hope can get the answer here.
In most of the die, we can see that the power bus(global distribute) in each layer is only expand in 1 way, either vertical or horizontal. Why can't we bend the power bus in a single layer? 1 of reason that i can think of is to reduced the cross talk between different layer but what if there is not other signal nearby, can we still go into multiple way in a single layer?
Another question is that, any side effect if we distribute a signal like VCC globally by using a single "wide" bus? Will current sinking through this bus causing a problem?
Last but not least, can someone recommend some books or papers regarding the basic of power bus distribution.
Thanks!
