There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
The objective of this proposed research is to perform thermal and power delivery network (PDN) analysis and optimization for emerging integration systems such as three-dimensional and 2.5 dimensional integrated circuits. The key contribution of this research is in fourfold. First, a compact thermal model is developed and used for analyzing conventional 2-D, emerging 2.5-D and 3-D architectures. Second, a novel 3-D stacking structure with microfluidic cooling, thermal isolation using air gap and mechanically flexible interconnects, and an extended heat spreader is proposed, evaluated and demonstrated. Third, thermal studies are performed focusing on 2.5-D bridge-chip based platforms and benchmarked with other 2.5-D and 3-D integration solutions. Fourth, a PDN modeling framework is developed and used to benchmark different 2.5-D integration platforms focusing on bridge-chip based 2.5-D integration. Last, an integrated framework analyzing the power, thermal and power delivery network simultaneously is proposed. The integrated framework accurately model the above metrics and remove the pessimism of using worst-constraints in IC design.
