The Delta-I ( DELTA I) problem occurs when drivers with fast rise times and high currents switch simultaneously on a module with high inductance. Due to this excessive switching, a noise pulse on the power supply can propagate through quiet drivers to receivers. If the noise is sufficiently large to penetrate threshold, a latch on a chain of gates from the receiver may be falsely set. A new algorithm which determines the probability that a DELTA I failure exists is presented.
