Sneak Circuit Analysis is an important task in
the safety analysis of systems that are responsible
for irreversible actions (fuses, emergency brakes,
etc.) The analysis ensures that inadvertent action
(or mis-action) cannot be caused because of a design
flaw.
SoHaR is a pioneer in the effort to streamline sneak
circuit analysis and reduce the effort and cost
involved in a comprehensive analysis. SoHaR has
developed a method/algorithm that does not require
or even make use of traditional network trees, but
rather focuses on circuit components which can
conduct current in either direction depending upon
the switching state of the circuit thus allowing for
sneak paths. This method lends itself to automation
which has been implemented in our tool SCAT The
automated procedure provides the design engineer or
reliability analyst with a simple yet powerful tool
for rapidly identifying and correcting sneak paths.
Furthermore, the analyst's task is reduced to
evaluating the significance of specific potential
sneak paths rather than applying "clue lists" to
circuit patterns for identifying the sneak paths.
