Book excerpt: "Conventional three-dimensional integrated circuits (3D ICs) stack multiple dies vertically for higher integration density, shorter wirelength, smaller footprint, faster speed and lower power consumption. Due to the large through-silicon-via (TSV) sizes, 3D design partitioning is typically done at the architecture-level With the emerging monolithic 3D technology, TSVs can be made much smaller, which enables potential block-level partitioning. However, it is still unclear how much benefit can be obtained by block-level partitioning, which is affected by the number of tiers and the sizes of TSVs. In this thesis, an 8-bit ripple carry adder was used as an example to explore the impact of TSV size and tier number on various tradeoffs between power, delay, footprint and noise. With TSMC 0.18um technology, the study indicates that when the TSV size is below 100nm, it can be beneficial to perform block-level partitioning for smaller footprint with minimum power, delay and noise overhead"--Abstract, leaf iii.
