New techniques are proposed to obtain better estimates and optimizations at higher levels of design abstractions, which are then used for library cell selection. A single object-oriented database repository is used during all phases of VLSI design to enhance the early design estimates. As compared to a relational database using sorted tables of attribute values, the proposed object-oriented cell library manager reduces search time for an appropriate cell, with m constraints among n cells, from O(nm) to O(m log n). The proposed method also reduces design cycle time by reducing the number of iterations due to mismatched performance estimates done in the earlier phases of a design.
