This paper presents an efficient method for optimizing power/ground (P/G) networks by widening wires and adding decoupling capacitors (decaps). It proposes a structured skeleton that is intermediate to the conventional method that uses full meshes, which are hard to analyze efficiently, and tree-structured networks, which provide poor performance. As an example, we consider a P/G network structure modeled as an overlying mesh with underlying trees originating from the mesh, which eases the taskdoi:10.1109/tcad.2003.818372 fatcat:gcw3ywijybculdvk4z5nln225e
