摘要:
Measurement of individual quiescent supply currents from multiple power supply pads located across a semiconductor die provides a means of characterizing across-die variation. A ratio is created by combining the individual pad supply current with the sum of all pad supply currents for a given die. An n-tuple is formed from the set of ratios for all pad supply currents to provide a unique signature for different across-die variation profiles.
