Abstract:
A method includes receiving a layout of an integrated circuit that includes a plurality of layers, one of the layers is selected and one or more tile number values are provided. A die area of the integrated circuit is partitioned into a plurality of tiles on the basis of the tile number values. It is determined, on the basis of the layout, if a portion of the selected one of the layers in the tile has an available space for inclusion of a test cell or a dummy cell, and a label indicative of a result is assigned to the tile. It is determined, on the basis of the labels assigned, if one or more space availability criteria are fulfilled and, if fulfilled, the labels are used for placing at least one of one or more test cells and one or more dummy cells in the layout.
