Systems and methods for probabilistic interconnect planning

Abstract

Systems and methods for interconnect planning which utilize probabilistic methodologies. One embodiment comprises a method for planning interconnect models in an integrated circuit design. Nets and a set of interconnect models that can be used to connect the pins of each net are first defined. For each net, the probability that each interconnect model will be used to connect the pins of the net is evaluated. Tiles in the integrated circuit design are then assigned probabilities indicating the likelihood that each of the interconnect models will traverse the tiles. A map is then generated to indicate probabilistic routing characteristics (e.g., probabilities of wire congestion, interconnect component congestion, power densities, interconnect model usage) based on the probabilities assigned to each of the tiles in the integrated circuit design. The map may then be output (e.g., printed or otherwise displayed) to a user or stored for later use.
