摘要： A system and method of performing microelectronic chip timing analysis, wherein the method comprises identifying failing timing paths in a chip; prioritizing the failing timing paths in the chip according to a size of random noise events occurring in each timing path; attributing a slack credit statistic for all but highest order random noise events occurring in each timing path; and calculating a worst case timing path scenario based on the prioritized failing timing paths and the slack credit statistic. Preferably, the random noise events comprise non-clock events. Moreover, the random noise events may comprise victim/aggressor net groups belonging to different regularity groups. Preferably, the size of random noise events comprises coupled noise delta delays due to the random noise events occurring in the chip.

摘要： A method for computing a Miller-factor compensated for peak noise is provided. The method includes mapping at least two delays as a function of at least two Miller-factors; determining an equation of the function; computing a peak noise; computing a peak delay resulting from the peak noise; and computing the compensated Miller-factor based on the equation and the peak delay. The function can be either a linear function or a non-linear function.
