Abstract
A method includes: receiving value changes corresponding to timestamped logic value changes in recorded signals from a verification run of an integrated circuit (IC) design; generating recorded logic vectors from the value changes, each of the recorded logic vectors being associated with a corresponding signal identifier, each of the recorded logic vectors including a recorded logic values over a window of consecutive clock cycles computed from one or more value changes associated with the corresponding signal identifier and having timestamps within the window of consecutive clock cycles; determining, by a processor, inferred logic vectors including inferred logic values corresponding to signals output by cells of the IC design based on propagating the recorded logic values of the recorded logic vectors through the cells; and computing per-cycle power characteristics of the IC design based on the recorded logic vectors and the inferred logic vectors.
