Abstract :
A method of handling uncertain statistical information and its (approximate) propagation through an IC is proposed, utilizing the concepts of fuzzy numbers and fuzzy arithmetic, combined with the propagation of moments method of statistical analysis, leading to a new method of propagation of fuzzy variance. A symbolic implementation of this method is proposed, allowing one to efficiently represent the relevant membership functions
