\section{Introduction}

Msc project Euler/Spider Diagram editor --- Euler/Spider Diagrams
|
|
could be used to model failure modes in components.
|
|
--- 2005 paper --- need for static analysis because of
|
|
high reliability of modern safety critical systems.

\section{Practical Experience: Safety Critical Product Approvals}
|
|
|
|
FMEA performed on selected areas perceived as critical
|
|
by test house.
|
|
Blanket measures, RAM ROM checks, EMC, electrical and environmental stress testing
|
|
|
|
\subsection{Practical limitations of testing for certification vs. rigorous approach}
|
|
|
|
State explosion problem considering a failure mode of a given component against
|
|
all other components in the system i.e. an exponential ($2^N$) order of processing resource rather than a polynomial i.e. $N^2$.
|
|
|
|
Impossible to perform double simultaneous failure analysis (as demanded by EN298~\cite{en298}).
