<https://github.com/The-OpenROAD-Project/OpenLane/issues/612|#612 Power Ring On One Layer>
New issue created by <https://github.com/donn|donn>
Requested by <https://github.com/shalan|@shalan>

*Prompt*

The power ring currently has vertical straps on one layer and horizontal straps on the other, using vias in the middle. These vias add considerable resistance.

*Proposal*

An option in OpenLane should be surfaced for the power ring to exist entirely on one layer.

*Alternatives*

The original setup will continue to exist.
