Our goal is to find classes of graphs that are RVGs. We obtain several results: 1. For 1 < k < 4, k-trees are RVGs. 2. Any graph that can be decomposed into two caterpillar forests is an RVG. 3. ...
In two-layer routing, one embeds processing components and their connections (sometimes called wires) in two layers of silicon (or other VLSI material). The components are embedded in both layers. ...
