+- Recording of vehicle data for visualisation
+- Simulation of complex scenarios in SIL/HIL test environments
+
+The software features time-based processing of multiple data streams and graphical editing of dynamic filter graphs. It also includes an SDK for custom plug-ins and reusable components, as well as components for data visualization in both 2D and 3D. This is was the
