1. A crosstalk analysis method comprising: using a computer to perform the following: executing a layout program; executing a crosstalk analysis program; acquiring, by the crosstalk analysis program, a plurality of parameters from a layout result generated by the layout program; estimating a crosstalk value according to the parameters; determining whether the crosstalk value is larger than a predetermined value; generating a layout suggestion when the crosstalk value is larger than the predetermined value; fabricating an integrated circuit using the layout result and the layout suggestion; and creating a database for storing the parameters by units of project, wherein the crosstalk value corresponds to a line segment of the layout result, and the layout suggestion comprises an angle of the line segments and a minimum distance between the line segment and an interference source.
