1. A method comprising: storing data defining nets and corresponding pins for connection in an integrated circuit design; storing data defining a plurality of interconnect models; based on the stored data, for each net, evaluating a probability that each interconnect model will be used to connect the pins of the net, and for each of a plurality of tiles in the integrated circuit design, assigning to the tile corresponding probabilities that each of the interconnect models will traverse the tile; generating a map of the integrated circuit design indicative of probabilistic routing characteristics based on the probabilities assigned to each of the tiles in the integrated circuit design; and presenting the generated map to a user.
