Abstract

Signal integrity closure is one of the key challenges in DSM (Deep- SubMicron) physical design. In this paper, we propose a physical design methodology which includes signal integrity management through noise analysis and repair at multiple phases of the design so that a quick noise convergence can be achieved. The methodology addresses both functional and delay noise problems in the design and is targeted for block, platform, and chip level physical design of SoC (System-On-Chip) designs. A number of case studies are presented to illustrate the effectiveness of the proposed methodology and to provide valuable insights useful for successful signal integrity management.
