Static noise analysis with noise window estimation and propagation

摘要

Static noise analysis simulates crosstalk functional noise by estimating a crosstalk functional noise window and by calculating the propagation of the noise window through a network. For example, the analysis can include simulations of injecting a noise window onto a network, propagating the noise window through the network until it reaches a register, and comparing the noise window with a register's sensitive window. The noise window for the net is calculated based on a duration of time in which noise glitches caused by capacitive coupling to aggressor nets can occur. The noise window is propagated through the net in a forward direction until the noise is attenuated or reaches a register's input. At the register's input, a sensitive window can filter the noise window so that only the portion of the noise window that coincides with the register's clock trigger time is considered in the noise analysis.
