<h3>Using Frama-C to grasp source code internals</h3>
<p>The C language has been in use for a long time, and numerous programs today make use of C routines. This
ubiquity is due to historical reasons, and to the fact that C is well adapted for a significant number of
applications (e.g. embedded code). However, the C language exposes many notoriously awkward constructs. precise
analyses despite the pitfalls of C</p>
<p><b>Many Frama-C plug-ins are able to reveal what the analyzed C code actually does. Equipped with Frama-C, you
can:</b></p>

<h3>Test robustness of your code</h3>
<p>Frama-C allows to verify that the source code complies with a provided formal specification. Functional
specifications can be written in a dedicated language, ACSL. The specifications can be partial, concentrating
on one aspect of the analyzed program at a time.</p>
<p>The most structured sections of your existing design documents can also be considered as formal
specifications. For instance, the list of global variables that a function is supposed to read from or write to
is a formal specification. Frama-C can compute this information automatically from the source code of the
function, allowing you to verify that the code satisfies this part of the design document, faster and with less
risks than a code review.</p>
