Sneak circuit analysis (SCA) is used for evaluating electrical circuits, with the intention of identifying latent (sneak) circuits and conditions that inhibit desired functions without component failure having occurred. Sneak circuits can occur in all types of electrical and electronic systems, so SCA is required for high-reliability systems. Sneak circuits can create sneak paths (which allow current to flow along an unexpected route) or sneak timing (which causes functions to be inhibited or to occur unexpectedly). 

Additional safety processes are performed iteratively throughout the life cycle as other specialty engineering disciplines become involved in the effort. These include Sneak Circuit Analysis (SCA) and Software Hazard Analysis (SWHA). 

Figure 3.12 shows a sample sneak circuit analysis worksheet. To perform an SCA, the analysis team will require the following ... 

SCA is a safety analysis technique for identifying a special class of hazards known as sneak circuits or sneak paths. SCA is accomplished by examining electrical circuits and searching out unintended electrical paths which, without...
