Henry Valdez, President of IDA Inc.
This
paper explains the state of the Integrated
Hardware/Software Sneak Analysis technique from the
development of the Baseline Analysis Tools to clue
application and through the completion of the integrated
analysis phase. Also, the advantages of integrating Sneak
Analysis with other design and safety analyses will be
discussed, such as an integrated Hardware/ Software Fault
Tree Analysis (FTA), and a Hardware/ Software Failure
Modes, Effects and Criticality Analysis (FMECA).

developed the Sneak Analysis technique for the manned space
program in 1967 to find unintended modes of behavior that
are not caused by component failure. Since that time, it
has been applied to many types of systems, including
military, nuclear, automotive, mass transit, medical, and
petrochemical. Complete systems including software,
hydraulics, pneumatics, as well as electronic hardware, can
be analyzed for sneak conditions. Circuitry can include
combinations of analog and digital technology. Hybrids and
application-specific integrated circuits (ASICs) can be
easily accommodated. This paper explains the basic steps in
the Sneak Analysis technique, shows the differences between
the Sneak Analysis approach and other design analysis
approaches, and provides several examples of sneak
conditions. Relationships to other design analyses are
discussed and advantages of integrating Sneak Analysis with
other design analyses are shown. Conclusions drawn from
actual applications are presented.
Sneak Analysis as a Quality Assurance Tool For The
Automotive Industry -

The
development and introduction of complex, highly integrated
electrical/ electronic and microprocessor based systems
into new products poses a major challenge to the automotive
industry. That challenge is to introduce these new
technologies while continually improving the quality of the
automotive product. Many of the tools needed to meet this
challenge have been developed in the aerospace industry and
are available to support automotive requirements. Sneak
Analysis is such a tool.
Sneak Analysis as a Software Reliability Improvement Tool -
SA SW Rel
Tool
The
development and introduction of complex, highly integrated
electrical/electronic and microprocessor based systems into
new products poses a major challenge to reliable system
operation. Sneak Analysis identifies and corrects
reliability-robbing design conditions, called sneaks, that
frequently evade detection by traditional analysis and
testing procedures.
