A peak current modeling method and system for modeling peak current demand of an integrated circuit (IC) block such as, e.g., a compilable memory instance. A current demand curve associated with the IC for a particular IC block event is obtained via simulation, for example. A defined time region associated with the particular IC block event is divided into multiple time segments, whereupon at least a first current value and a second current value for each time segment is obtained based on the current demand curve. Thereafter, the current demand curve is approximated, on a segment-by-segment basis, using a select approximate waveform depending on a relationship between the first and second current values.
