Title: Through-Silicon Via Reduction (TSV) in 3D VLSI Circuits focused on Bulk and SOI Technologies
Funding Agency: FAPERGS - Fundação de Amparo à pesquisa do Estado do RS
Call:
Grant: 10/0216-7
Amount: 7,000.00 Reais
Start: 01/01/2010
End: 31/12/2011
Summary:

The main objective of this research project is to implement a design flow to reduce the number of vertical interconnections (TSV or 3D-vias) in 3D VLSI circuits using Bulk and SOI technologies. We seek to minimize the area of a 3D VLSI circuit and analyze the impact on the area when applied to different manufacturing technologies. The effects generated by reduction help the insertion of thermal vias, as well as reducing the total size of the connections (which directly affects the timing of the circuit). Initially, the emphasis will be on random logic blocks (cell level) with small granularity, being possible to extend to larger granularities, such as IP level.
