GLOBAL PEAK CURRENT SEARCHING METHOD

摘要

The present invention relates to a global peak current searching method of logic level for system semiconductor consumption power analysis and voltage drop analysis comprising stages of: calculating signal line energy value of each event occurrence time by extracting time data and slew rate data from a value change dump (VCD) file; calculating local energy at each event occurrence time based on energy value of signal line; calculating global energy by section by summing local energy values locating within preset time section; and ranking global energy value calculated by each section and setting at least one value as global peak current value.
