  • Method of estimating a local average crosstalk voltage for a variable voltage output resistance model
    Patent number: 6990420
    Abstract: A method includes steps of: (a) receiving as input a waveform of a transient signal as a function of time for an aggressor net; (b) finding a peak value of the waveform and a corresponding peak time of the waveform propagated from the aggressor net to a victim net; (c) defining a selected time interval within the waveform at the victim net that includes the peak value and excludes features of the waveform not associated with the peak value wherein the selected time interval begins at a first time and ends at a second time; (d) calculating a weighted value of a function of the waveform at the first time and the second time; (e) calculating a local average value of the waveform as a function of the peak value and the weighted value; and (f) generating as output the local average value of the waveform.
