A global leader in automotive software faced challenges in visualizing all automobile components in a single view, making error detection difficult and limiting system connectivity. Physical data simulation was time-consuming and inefficient. ITHENA implemented a System Mapping solution featuring digital visualization, customizable layouts, color-coded error detection, a drag-and-drop ECU map designer, and digital simulation. This solution streamlined system design, improved efficiency, and enhanced error detection. With faster diagnostics and better connectivity, the client significantly improved their development process and operational performance.
