Abstract :
A technique for predicting the yield distribution of CMOS circuits based on electrical parameter distributions is presented. This technique uses the mean and standard deviation of the measured threshold voltage and mobility of NMOS and PMOS transistors to project the yield of the circuit in a specified design window. The method thus provides a quantitative means of carrying out tradeoffs between design windows and final product yield
