Abstract:
A method of generating a plot that evinces common result regions of a test as a function of at least one controllable input parameter, each of said at least one input parameter having a predetermined range and a predetermined resolution, comprising the steps of:defining an overall plot region being a function of a maximum and a minimum of each said predetermined range, said overall shmoo plot region including a plurality of test conditions, each of said test conditions corresponding to a value of each of said at least one input parameter; subdividing said overall plot region into at least two sub-regions, each of said sub-regions having a sub-region boundary, and evaluating, for each of said sub-regions, a plurality of boundary test conditions on said sub-region boundary according to said test, so as to assign a test status to each of said plurality of boundary test conditions; and, for each of said sub-regions with at least a predetermined threshold number of boundary test conditions having a common test status, designating said sub-region with said common test status, and for each of said sub-regions not having at least said predetermined threshold number of boundary test conditions with a common test status, designating said sub-region with an indeterminate status.
