1. A method for simulating crosstalk in a signal path from a first group of signal paths using an electronic device, wherein the signal path includes one or more series-coupled stages, and wherein each stage in the one or more series-coupled stages includes a driver coupled to a receiver, comprising: calculating time-delay contributions of a first group of crosstalk aggressors to a total time delay of the signal path, wherein the first group of crosstalk aggressors is associated with the first group of signal paths and gives rise to crosstalk delay in the signal path, and wherein the individual time-delay contributions of the first group of crosstalk aggressors are modeled with corresponding random variables; calculating time-delay contributions of a second group of crosstalk aggressors to the total time delay of the signal path, wherein the time-delay contributions of the second group of crosstalk aggressors are modeled using corresponding non-statistical deterministic values; determining the total time delay of the signal path based at least in part on the calculated time-delay contributions of the first group crosstalk aggressors and the second group of crosstalk aggressors; and calculating an upper bound on a probability of the total time delay of the signal path using an inequality relationship.
