Research Focus Design automation for interposer-based 3D ICs Interposer-based 3D ICs—also known as 2.5D ICs—promise
higher yield and better heat dissipation over classical 2D ICs. Such 3D
ICs are currently commercially available in a few products, like
FPGAs and GPUs, and they are viable contenders for the
next-generation chip market. However, the designing of these products
requires some notable manual intervention for placement, simulation,
verification, etc.; available tools are still inadequate according
to academia and industry experts. Structure of interposer-based 3D ICs To address this issue, we are developing the automated design methodologies for interposer-based 3D ICs,
including approaches for die placing, interposer routing, thermal analysis and pin assignment.
Research Interests Overview of the selected design methodologies Optimal Die Placement on the Interposer Our key ideas are to leverage the constraint-satisfaction problem (CSP) formalism in combination with a branch-and-bound (B&B) algorithm, and to develop several novel techniques for early identification and pruning of unpromising configurations. Such pruning techniques dramatically, yet accurately, confine the solution space and quickly rule out unpromising placements. Thus, we obtain optimal placement solutions in significantly shorter runtime than prior art, and we can optimally handle larger problem instances than prior art. Downloads Please consider
