Abstract :
Improving debug techniques for logic failures is a constant imperative. This paper describes the results of implementing a logic mapping methodology that integrates in-line manufacturing defect data and scan-based diagnosis for a complex microprocessor. The correlation between the physical failure analysis results and defect inspection data is presented and analyzed. Methods to improve the percentage of `hits´ are explored, supported by a detailed account of challenges and obstacles encountered during the experiment. Finally, the paper also briefly highlights the amount of time that can be saved in process debug through the usage of logic mapping
