Method of and system for generating a binary shmoo plot in N-dimensional space

A method of generating a shmoo plot as a function of a performance test and a plurality of parameters, each of said parameters having a predetermined parameter range and a predetermined parameter resolution, comprising the steps of:

• defining an overall shmoo plot region as a function of a maximum and a minimum of each said predetermined parameter 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 plurality of parameters;
• subdividing said overall shmoo plot region into sub-regions, and evaluating each of a plurality of corners of each of said sub-regions according to said performance test, so as to assign a test status, including either a pass status or a fail status, to each of said corners depending upon a result of said performance test;
• for each of said sub-regions having all of said corners assigned a common status, designating said sub-region with said common status, and for each of said sub-regions not having all of said corners assigned a status, repeating said subdividing, evaluating and designating steps until all of said sub-regions have been designated with said test status.

A method of generating an N dimensional shmoo plot as a function of a performance test and N parameters, each of said parameters having a predetermined parameter range and a predetermined parameter resolution, comprising the steps of:

• defining an overall shmoo plot region as a function of a maximum and a minimum of each said predetermined parameter 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 N parameters;
• subdividing said overall shmoo plot region into 2N equal sub-regions, each said sub-region having 2N corner test conditions, and evaluating each of said 2N corner test conditions of each of said 2N sub-regions according to said performance test, so as to assign a test status, including either a pass status or a fail status, to each of said 2N corner test conditions depending upon a result of said performance test;
• for each of said 2N sub-regions having all of said 2N corner test conditions assigned a common status, designating said sub-region with said common status, and for each of said 2N sub-regions not having all of said 2N corner test conditions assigned a status, repeating said subdividing, evaluating and designating steps until all of said sub-regions have been designated with said test status.
