Abstract:
1. A system for analyzing noise comprising: an error information storage unit storing threshold values of malfunction factors that create a malfunction of a victim receiver cell due to a noise; an error criterion generation section configured to select the threshold values from the error information storage unit, and to generate an error criterion according to the victim receiver cell by plotting the threshold values and subjecting the threshold values to smooth processing; a noise analysis section configured to measure the malfunction factors; a comparison section configured to compare the measured malfunction factors to the error criterion, and to judge whether the noise will create a malfunction of the victim receiver cell when the malfunction factors meet the error criterion; and a net analysis section configured to distinguish a net through which a clock signal is propagated from another net through which a general signal other than the clock signal is propagated and to order the error criterion generation section to eliminate the error criterion relating to the malfunction factors generated in rising and falling signals propagated through the net through which the general signal is propagated.
