Abstract :
In this paper, we provide a new efficient and accurate congestion model embedded into a floorplanner to estimate the congestion of floorplans. It is based on probabilistic analysis and a new concept of Irregular-Grid which uses the routing information to determine the evaluating regions instead of fixed-size grids. Three complete experiments are performed and the experimental results show the correctness, accuracy and efficiency of our new congestion model.
