. HeliX QAC can be used for quality assurance of C source code and checking the code for conformance to coding guidelines such as MISRA C. Other functionality includes the ability to calculate code metrics for projects with large code-bases. The tools operate through an integrated development environment (IDE) designed to help maintain and understand old and new code using detailed cross references and a variety of graphical views. The tools can be used with a command line interface, and graphical IDE can be called to display the result.
