ItemCongestion and Power Integrity Aware Placement and Routing for 3D Packaging(Georgia Institute of Technology, 2004-04-23) Minz, Jacob Rajkumar ; Choi, Jinwoo ; Swaminathan, Madhavan ; Lim, Sung KyuOne of the major concerns for a 3-D package is to deal with power supply noise. Decoupling Capacitances (decap) allocation is a powerful technique to suppress power supply noise. In this work we integrate noise analysis and decap estimation in the floorplanning process. We also use the global routers results directly to estimate congestion and tight couple global routing with floorplanning to get a better area/congestion trade-off. Our experiments prove the quality of our approach. We obtain improvements in both decap amount and congestion with only small increase in area, wirelength and runtime.
