    • Simultaneous optimization of the area, wirelength and TSVs in a 3D IC design


      More Details Abstract Fulltext PDF

      The technology of a three-dimensional integrated circuit (3D-IC) is an emerging approach for improving performance. In comparison to a standard 2-D IC design, which arranges all of the devices on a single planar layer, a 3D-IC stacking of many tiers enables more devices to be placed close together, resulting in a significant area and wirelength reduction. Designing a 3D-IC introduces an extra parameter to be considered while assigning a layer to any circuit component where different layers are connected Through Silicon Vias. Inthis paper, we have applied the Parallel-PSO approach to optimize the area, wirelength of the layout and the number of TSVs to connect the different layers simultaneously. The results are obtained and compared with the benchmark circuits available with MCNC and GSRC.
