Abstract:
1. A non-transitory computer-readable recording medium which stores a failure analyzing program that derives a function that provides a correlation between a plurality of failure factors and an error or a failure rate of each of a plurality of failure elements indicating occurrence of a failure of an actual chip on the basis of result of measurement on the actual chip and estimates a correct failure factor on the basis of the derived function, the failure analyzing program instructing a computer to execute: if each of the plurality of failure elements includes a number of failure candidates including a first failure factor that causes the failure in the element, generating a combination of failure candidates one for each of the plurality of failure elements; deriving the function based on the generated combination of failure candidates; calculating a cost of the derived function; and selecting one of a plurality of the generated combinations of failure candidates that minimizes the cost.
