Practical Implementation of Soft Defect Localization (SDL) in Mixed Signal and Analog ICs Available to Purchase

Dynamic Laser Stimulation (DLS) techniques for Soft Defect Localization (SDL) have been well documented for logic devices [1][2]. More recent literature has broadened the traditional SDL pass/fail mapping by employing multiple device parameters including power analysis [3], spectrum response [4], and other analog variations [5]. A practical and efficient implementation of SDL without the use of synchronization or traditional Automatic Test Equipment (ATE) hardware is presented. A dynamic way of analyzing many parameters of mixed signal and analog ICs can be obtained through the use of a high waveform rate oscilloscope, feedback loop, or discrete comparator. Multiple case studies are shown to illustrate the methodology.
