Verification coverage of embedded multicore applications

Verification of embedded multicore applications is crucial as these applications are deployed in many safety critical systems. Verification task is complicated by concurrency inherent in such applications. We use mutation testing to obtain a quantitative verification coverage metric for mullticore applications developed using the new Multicore Communication API (MCAPI) standard. MCAPI is a lightweight API that targets heterogeneous multicore embedded systems. We developed a mutation coverage tool and performed several experiments on MCAPI applications. Our experiments show that mutation coverage is useful in measuring and improving the quality of the test suites and ultimately the quality of the multicore application.
