Method for optimized evaluation of parameter influencing circuit board signal transmission quality

The invention provides a method for the optimized evaluation of a parameter influencing circuit board signal transmission quality. The method comprises the following steps of: establishing a first experimental design table of few experiment times, and obtaining eye diagram heights of each group of experiments in the first experimental design table through simulation experiments; and then fitting the empirical formula of the eye diagram heights through a mathematical regression algorithm according to the eye diagram heights. The method also comprises the steps of: establishing a second experimental design table by a full-factorial experiment method; calculating the eye diagram heights of each group of experiments in the second experimental design table according to the fitted formula; and selecting a plurality of groups of experiments each having the eye diagram height greater than 1 from the second experimental design table. The method further comprises the steps of calculating the average value of the eye di
