Claim One:
1. A method of determining the behavior of an electronic system comprising electronic components under variability, the method comprising: (1) for at least one parameter of at least one of the electronic components, showing variability defining a range and a population of possible values within the range, each possible value having a probability of occurrence, thereby defining an input domain; (2) selecting inputs randomly from the input domain, wherein a probability to sample (PTS) is obtained from a probability of occurrence (PTOIR) as PTS inputdomain =(PTOIR inputdomain ) (1−gamma) , wherein gamma is a specific non-zero number in the range of about −1 to +2; (3) performing a simulation to obtain performance parameters of the electronic system, thereby defining an output domain sample; and (4) aggregating results of individual computations into a parameter/variability of the electronic system and assigning a frequency of occurrence FoO to the resulting sample being FoO outputdomain =(PTOIR inputdomain ) (gamma) , the parameter/variability and the frequency of occurrence defining the behavior, wherein the method further comprises condensing a number of possible values of at least one variability parameter by clustering the number of possible values and using a domain of these clustered values for randomly selecting inputs.
