This paper focuses on low-power and low-slew clock network design and analysis for through-silicon via (TSV) based three-dimensional stacked ICs (3D ICs). First, we investigate the impact of the TSV count and the TSV resistance-capacitance (RC) parasitics on clock power consumption. Several techniques are introduced to reduce the clock power consumption and slew of the 3D clock distribution network...
In this paper, three effective design techniques are presented to effectively reduce the clock power consumption and slew of the 3D clock distribution network: (1) controlling the bound of through-silicon-vias (TSVs) used in between adjacent dies, (2) controlling the maximum load capacitance of the clock buffer, (3) adjusting the clock source location in the 3D stack. We discuss how these design factors...
Heat removal and power delivery have become two major reliability concerns in 3D stacked IC technology. For thermal problem, two possible solutions exist: thermal-through-silicon-vias (T-TSVs) and micro-fluidic channel (MFC) based liquid cooling. In case of power delivery, a highly complex power distribution network is required to deliver currents reliably to all parts of the 3D stacked IC while suppressing...
One of the biggest challenges in 3D stacked IC design is heat dissipation. Incorporating thermal vias is a promising method for reducing the temperatures of 3D ICs. The bonding styles between device layers impose certain restrictions to where thermal vias may be inserted. This paper presents a whitespace redistribution algorithm that takes bonding style into consideration to improve thermal via placement,...
