Abstract: Various implementations described herein are directed to a method that identifies a memory instance with multiple tile-cells. The memory instance has memory instance leakage data, and each tile-cell of the multiple tile-cells has tile-cell leakage data. The method subdivides the multiple tile-cells into multiple categories based on a relationship between the memory instance leakage data and the tile-cell leakage data. The method obtains measured leakage data for each tile-cell of the multiple tile-cells by simulating the memory instance based on the memory instance leakage data and the tile-cell leakage data for each category of the multiple categories. The method determines a combined leakage of the memory instance by combining the measured leakage data for each tile-cell of the multiple tile-cells.
