This is another in a series of guideline publications aimed at improving Fleet readiness by means of more reliable Navy material. This guideline is intended to expand the knowledge and understanding of the sneak circuit analysis approach among Navy and industry managers and engineers. The electronics systems being designed and manufactured for the Navy are increasing in complexity. One result of these complex system designs is the designer is not able to have a complete view of the detailed interrelationship between components and functions. As a consequence, the design may contain unexpected electrical paths or logic flows that, under certain conditions, will produce undesired results or will prevent intended functions from occurring. These situations are labeled "sneak circuits" and can be identified in the design phase through the use of sneak circuit analysis. I am convinced that the thoughtful examination of this analysis technique and its broader but selective application can have a positive impact on system reliability and on Fleet readiness.
