Abstract
Disclosed are method, system, and computer program product for a method and system for a fast and stable placement/floorplanning method that gives consistent and good quality results. Various embodiments of the present invention provide a method and system for approximate placement of various standard cells, macro-blocks, and I/O pads for the design of integrated circuits by approximating the final shapes of the objects of interest by one or more probability distribution functions over the areas for the objects of interest with improved runtime and very good stability. These probability distributions are gradually localized to final shapes satisfying the placement constraints and optimizing an objective function.
