System and method for analyzing noise

A computer implemented method for analyzing noise comprising:

• generating an error criterion according to a victim receiver cell, by plotting threshold values of malfunction factors that create a malfunction of the victim receiver cell due to a noise and subjecting the threshold values to smooth processing;
• measuring the malfunction factors;
• comparing the measured malfunction factors to the error criterion;
• judging whether the noise creates a malfunction of the victim receiver cell when the malfunction factors meet the error criterion;
• distinguishing 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
• eliminating the error criterion relating to the malfunction factors created in rising and falling signals propagated through the net through which the general signal is propagated.

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,
• wherein the error information storage unit stores at least one of a noise voltage in the rising signal transmitted to the victim receiver cell, a noise duration in the rising signal transmitted to the victim receiver cell, a noise voltage in the falling signal transmitted to the victim receiver cell, a noise duration in the falling signal transmitted to the victim receiver cell, and the victim receiver cell load capacity as the threshold values.
