Fast Shmoo Plot
This reduction in test time is achieved by not testing every possible
parameter pair in the defined test region.
Instead a coarse (low resolution) plot is first made to determine the
approximate position of the transition and then the tool performs a
high resolution search only within a certain distance of the estimated
pass/fail and fail/pass transition points.
This high resolution search area is determined by the application of a
special algorithm to the pass/fail results that are obtained from the
initial coarse search.
