1. A method for generating a boundary of a Schmoo plot, comprising: selecting a plurality of seed points having a resolution that is less than or equal to ½ the acquisition resolution indicated by a smoothness of a representative Schmoo boundary; performing a coarse boundary search to identify a plurality of test points that are within an acquisition resolution of the boundary; an interpolation processor interpolating the test points that comprise a coarse boundary to produce a fine estimate of the boundary.
