Abstract
A method, system, and computer program product are provided for distributing net power accurately. A workload is simulated operating on an integrated circuit. Net switching activity is determined for a set of nets and a set of subnets in the integrated circuit. Net switching data is generated based on the net switching activity. A net power value is calculated for each individual net and each individual subnet using the net switching data and a net capacitance for each individual net or subnet. Each calculated net power value is assigned to one of a set of source devices that drives the individual net or subnet, wherein the net power is distributed accurately. A net power assignment list is generated based on the assigning of each net power value to one of the set of source devices that drives the individual net or subnet.
