Claim 16:
17. A method for generating defect criticality comprising:
identifying defect results including a defect and a defect location of the defect;
receiving fault test recipes, wherein each fault test recipe is configured to test one or more of a plurality of potential faults at a plurality of testing locations; and
identifying a plurality of N-detect parameters, wherein each N-detect parameter of the plurality of N-detect parameters is associated with a testing location of a potential fault of the plurality of potential faults and is based on a countable number of times the fault test recipes are configured to test the potential fault;
determining a plurality of weighting parameters based on the plurality of N-detect parameters, wherein the plurality of weighting parameters are associated with the plurality of testing locations;
generating the defect criticality for the defect based on at least:
a proximity between the plurality of testing locations of the plurality of potential faults and the defect location of the defect; and
the plurality of weighting parameters associated with the plurality of testing locations.
