The embedded C code is automatically generated from Simulink open-loop controller models. Its diverse features (decision logic, floating-point and pointer arithmetic, rate limiters and state-flow systems) and the extensive use of floating-point variables make verifying the code highly challenging. Our study reveals large discrepancies in coverage - which is at most only 20% of all requirements - and tool strength compared to results from the main annual software verification competition. A hand-crafted, simple extension of the verifier CBMC with k-induction delivers results on 63% of the requirements while the proprietary BTC EmbeddedValidator covers 80% and obtains bounded verification results for most of the remaining requirements.}}@COMMENT{Bibtex file generated on }
