Can you provide a reference? As far as I know Ada has not ever been used. I am familiar with most of the current ECU's and almost all are using the same parts implemented in C with some of the ISO/IEC 18037 additions. > How do you achieve the "principles of strong typing" using C? Each of the automotive companies have internal design rules that are company mandated. I am generally impressed to the degree that automotive coding standards are maintained. misra is often looked at as a set of guidelines but most automotive companies use misra as one of many sources for their internal standards.
