Overview
</dt>
<dd><p>
CaFE (CaRet Frama-C Extension) is a small model-checker dedicated
to prove CaRet properties over C programs.
<a
href=
"https://doi.org/10.1007/978-3-540-24730-2_35"
>
CaRet
</a>
is
"a temporal logic of nested calls and returns", i.e. a flavor of
temporal logic well suited to describe a program's call stack.

CaFE
</a>
is available as a
separate open-source plug-in. Once installed, it will be activated by
the
<tt>
-cafe
</tt>
option, while
<tt>
-cafe-formula
</tt>
allows specifying
the file in which to formula to be verified lies. A typical command will
thus be the following:
<pre>
frama-c -cafe file.c -cafe-formula file.caret
</pre>
</p>
<p>
Note that CaFE uses
<a

Eva
</a>
internally to compute
an over-approximation of the states of the program.
