The Communication Matrix Manager is a stand-alone software product for handling communication matrices conveniently, quickly, and affordably. It provides graphical representations of the content of common communication matrix formats. The representation is independent of the communication matrices and includes a hierarchical view of the different elements, the properties of the elements, filters, and dedicated views. You can easily compare the properties from many communication matrix elements, e.g., clusters, channels, ECUs, PDUs, originating from several communication matrices, which makes it possible to find deviations quickly, even in log files. The software makes detecting changes and performing consistency checks easy and user-friendly.
