CBMC viewer
CBMC is a model checker for C. This means that CBMC will explore all possible paths through your code on all possible inputs, and will check that all assertions in your code are true. CBMC can also check for the possibility of memory safety errors (like buffer overflow) and for instances of undefined behavior (like signed integer overflow). CBMC is a bounded model checker, however, which means that using CBMC may require restricting this set of all possible inputs to inputs of some bounded size.
CBMC Viewer is a tool that scans the output of CBMC and produces a browsable summary of its findings.
