Can I create the neite power structure, I mean both horizontal and vertical lines of core rings, vertical strips and horizontal power stripes using a single metal ( top metal). Is this a right methedology to follow?
I just want to use top metal for power structure. So Can I create the entire power structure using a single metal layer?
Technicalyyou can do this with no violation of anything.
Problems begin when you try to do this for more then one net in one layer. Any ring you use for power net in one layer makes areas (inside or outside) unreachable for another power net without jumping to second layer. If you can overcome this situation, nothing could stop you from using only one metal layer for poer routing.
