Abstract :
Sneak analysis complements simulation and testing by uncovering problems that may not be otherwise detected. Sneak analysis does not predict system behavior for component failures or specific operational scenarios and, therefore, is not a replacement for simulation and testing. Simulation can be used to better understand the impact of conditions uncovered by sneak analysis and to evaluate fixes. Sneak analysis can reduce schedule risks and costs by detecting errors before fabrication. Detection of potential operational problems through sneak analysis, including those which might appear as intermittent failures, can reduce operating costs and improve dispatch reliability. The detailed topological diagrams produced during sneak analysis are also useful for other analyses, evaluating design changes, and test planning and troubleshooting
