Accurate pin-based memory power model using arc-based characterization

摘要

A pin-based memory power modeling method using arc-based characterization includes steps as follows. All power arcs of a memory model are identified and characterized. A power arc is selected from the identified and characterized power arcs. Output bus switching power is computed by removing overlapping power using the selected power arc, and a temporary value for various input ramp times and output loads is derived. Output pin power for the selected power arc is calculated using the temporary value and a ratio of a number of output bits switching over an entire bus width. Switching power for the selected power arc is calculated by a power estimation tool based on port activity and an input intrinsic power value.
