Abstract
A system and method for designing a structure such as a circuit. First the sensitivity of a circuit performance function (sensitivity data set - SDS) to at least one physical parameter is determined. Then, an estimated distribution of the design function calculated by using the SDS and random parameter values. Subsequently, the parameters corresponding to the estimated distribution was used to accurately calculate the tail. The tail is compared to a predetermined design objectives. If the objectives are not met, the design is modified and the calculation steps repeated until the design objectives are met.
