Computer-Aided 3D ICs Layout Design
TLDR
A new framework for visual kind of intelligent layout design is presented, where a shape grammar generates possible design solutions while intelligent algorithms control the direction of the solution space exploration.Abstract:
Computer-aided 3D ICs layout design requires efficient search of large and discontinuous spaces and no deterministic algorithms are able to perform such a task. The paper presents a new framework for visual kind of intelligent layout design. In the proposed approach a shape grammar generates possible design solutions while intelligent algorithms control the direction of the solution space exploration. Although the method is not limited to a particular design assignment, the paper focuses on a 3D ICs layout problem to demonstrate its potential.read more
