    Arguing formally about flight control laws
    (Institute of Electrical and Electronics Engineers Inc., 2015) Jeppu, N.Y.; Jeppu, Y.V.; Murthy, N.
    Flight control law software have errors. Some are found during the extensive testing and certification process and others pass through causing accidents. The testing of flight control software indicates that the code and the model match. But it is very difficult to ensure if the model was correct in the first place. Model checkers like Mathworks Simulink Design Verifier check the models against formally defined conditions and system behavior. The tool can come up with counterexamples that can fail an assertion or proof. A study is done on how easy or difficult it is to teach engineering students this formal process. The problem statement, the Simulink models and the outcome of the study in terms of advantages and disadvantages of using Simulink Design Verifier is highlighted in this preliminary study. © 2015 IEEE.

    Teaching formal methods at undergraduate/graduate level: The three perspectives
    (Institute of Electrical and Electronics Engineers Inc., 2018) Jeppu, N.; Jeppu, Y.; Kavitha Devi, M.K.K.
    Formai methods provide easy way of validating properties about systems. These methods are in existence since the last 50 years but have not been used fully by the industry as an engineering tool. One of the challenges of acceptance is education. Educating engineering students to take up formal methods is a challenge. This paper looks at these aspects of formal methods by providing demonstration of its usefulness on a recent failure. A few challenges of teaching formal method are described and three perspectives of formal methods are explained. The viewpoints are from a student who has worked on this, a teacher who teaches this and an industry practitioner of formal methods. We advocate an industry academia partnership to overcome some of these challenges of teaching formal methods to students. © 2017 IEEE.
