Abstract
Various embodiments provide for grouping cells in a cell library based on iterative clustering, which can be used for pruning the cell library. In particular, various embodiments provide for grouping cells in a cell library based on iterative clustering in view of a criterion (or cell attribute), and for pruning of the cell library based on the grouping of cells, which can optimize the cell library for the criterion. For instance, some embodiments provide for grouping cells in a cell library based on iterative clustering in view of leakage power and then applying cell library pruning to optimize for cell leakage power.
