For each benchmark, the verification engine was invoked by manually setting file name, timeout, and bit-vector-arithmetic solver7.
Such an approach is composed of digital-filter verification rules and the verification engine itself.
For instance, if the unwinding bound is set to k, then the verification engine produces k VCs to check for overflows, which are harder to be checked by an SMT (or SAT) solver.
In this work, the efficient SMT-based bounded model checker (ESBMC) tool is used as the verification engine, since it was one of the most efficient BMC tools, for bit-vector programs, in the last software verification competitions [45 47].
The expected behavior will be as shown in Fig. 2, which means that the verification engine is not expected to detect overflow failures, as in the previous case.
If the verification engine is executed for the implemented model, then it finds a particular initial condition that leads the system to a limit cycle.
But Matt Hunter, founder of the Essay Verification Engine, or EVE (www.canexus.com), an antiplagiarism service based in Sackville, New Brunswick, said that software like his usually uncovered even subtle dishonesty.
It makes use of an automatic checking and verification engine that works on the VHDL designs submitted by the students.
Then, the de-identified and HIPAA-compliant data were sent to the Datalys Center where it was examined by data quality control staff and a verification engine (VE) (Kerr et al. 2014b).
By July 14, the verification had indeed disappeared, though it's still not clear exactly why.
