Abstract
A present invention discloses an automated method to generate an eye-plot for signals produced by a simulation or captured hardware results. The automated approach is customizable in that the designer may specify input parameters to customize the analysis to fit the needs of the user. The eye-plot is then generated. The eye-plot may be output on the printer, displayed on the video display or even stored in secondary storage for subsequent review and use.
