Abstract:
A computer-readable medium having stored therein computer-readable program codes that when executed cause a computer system to perform a method of providing a power consumption model for a physical circuit of an integrated circuit device, said method comprising the steps of:a) identifying a set of signal pins for a library cell representative of said physical circuit and storing said set of signal pins into a memory; b) designating at least one output signal pin of said library cell and storing a signal pin designation thereof into said power consumption model of said library cell within said memory; c) associated with said designated output signal pin, defining a first set of signal pins, wherein a transition on one signal pin of said first set causes said designated output signal pin to transition and wherein said first set contains more than one signal pins; d) associated with said designated output signal pin, defining a first power consumption function representative of power consumed by said physical circuit when a transition on one signal pin of said first set causes said designated output signal pin to transition, said first power consumption function also representative of power consumed by said physical circuit when a transition on another signal pin of said first set causes said designated output signal pin to transition; and e) storing said first power consumption function and said first set into said power consumption model for said library cell of said memory.
