Abstract
A system and method for testing the data propagation time in an integrated circuit at relatively low speed is described herein. The method uses at least two parallel circuits comprising a data circuit and a clock circuit, wherein these parallel circuits are provided with at least one inverter for sensing the feeding current of each circuit so as to obtain current pulses that are transformed into binary signals forwarded to a tester that measures the delay time between these signals.
