ABSTRACT:
Method, apparatus, and computer readable medium for determining signal routing cost within an integrated circuit is described. In an example, the integrated circuit is divided into topology units and includes routing resources. A respective span is determined in terms of one or more of the topology units for each of the routing resources. A cost value is assigned to each of the routing resources using the respective span associated therewith. A routing resource is selected from the routing resources. At least one distance between the routing resource and at least one other of the routing resources is calculated. A future cost value for the at least one distance is computed using the cost value assigned to the routing resource.
