The processing times and input frequencies have four different distributions to select from: constant, triangular, normal and user defined. The constant distribution is the simplest of the four: the duration of the activation is always the same. The triangular distribution generates a random number so that the number is between the minimum and maximum values with the stated peak or top value.
