Area estimation of IC layouts has become an important requirement for early design and top-down chip planning tools. Especially the relation of area and aspect ratio (shape function) is necessary for chip planning. Statistical models have been published with good results for standard cell blocks with near unity aspect ratios. A model is presented for the prediction of shape functions for aspect ratios up to 1:5. The model is based on the shape and connectivity of adjacent cells. It can be used for many different design styles and has been tested for standard cell blocks for the placement of general cells.
