\section{discovering a `new' failure mode in a component}

Give general idea of how a new failure mode can be integrated into the model.

How it may cause a new symptom but may not.

How it will generally be limited to small sections of th FMMD tree.


Give specific example, pretend a new failure mode is discovered in a SCHOTTKY diode.

Often an electronic component will have a new failure mode `discovered'
I am using as an example a diode which has an exponential relationship
with temperature and reverse leakage current. This is
a failure mode that would not be initially considered in a design.
But when combined with high value resistors could give incorrect voltage readings in some circuits.
I how the FMMD model can have this new failure mode added and what
impact it has on the FMMD data model.
