An Enhanced Design Methodology for Resonant Clock Trees

Giovanni De Micheli, Xifan Tang, Vasileios Pavlidis, Somayyeh Rahimian Omam

Clock distribution networks consume a considerable portion of the power dissipated by synchronous circuits. In conventional clock distribution networks, clock buffers are inserted to retain signal integrity along the long interconnects, which, in turn, sig ...

3.5-D Integration: A Case Study

Giovanni De Micheli, Vasileios Pavlidis, Pierre-Emmanuel Julien Marc Gaillardon, Shashi Kanth Bobba, Ciprian Seiculescu

Two diverse manufacturing techniques for building 3-D integrated systems are vertical integration with Through-Silicon-Vias (TSVs), also referred to as 3-D TSV integration, and 3-D monolithic integration. In this paper, we present a hybrid integration sche ...

Timing Uncertainty in 3-D Clock Trees due to Process Variations and Power Supply Noise

Giovanni De Micheli, Xifan Tang, Vasileios Pavlidis, Hu Xu, Wayne Burleson

Clock distribution networks are affected by different sources of variations. The resulting clock uncertainty significantly affects the frequency of a circuit. To support this analysis, a statistical model of skitter, which consists of clock skew and jitter ...

Effects of Process Variations on 3-D Global Clock Distribution Networks

Giovanni De Micheli, Hu Xu, Vasileios Pavlidis

In three-dimensional (3D) integrated circuits, the effect of process variations on clock skew differs from 2D circuits. The combined effect of inter-die and intra-die process variations on the design of 3D clock distribution networks is considered in this ...
