Abstract

Advanced manufacturing and packaging techniques are permitting a glimpse at the near-future, where wires can go in three dimensions, and ICs made in diverse processes can be assembledtogether--sandwich like--to achieve ever higher levels of integration. This article focuses on a specific CAD problem in connection with 3D ICs: how to partition, place, and wire a design subject to various constraints on power, timing, and manufacturability.
