Abstract: Various embodiments provide for clustering-based grouping of cells in a cell library, which can be used for pruning the cell library. In particular, various embodiments provide for a clustering-based grouping of cells in a cell library based on 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 a clustering-based grouping of cells based on leakage power and then applying cell library pruning to optimize for cell leakage power.
