New trace synchronization method for AUTOSAR Time Synchronization/PTP


With AUTOSAR Time Synchronization, it is possible for ECUs to continuously synchronize their clocks in the network. The synchronization takes into account the message delays of complex networks and can achieve accuracies in the nanosecond range.

With the current version of ECU-TEST, the correct implementation of this protocol can be tested in the trace analysis. In addition, the globally synchronized time can be used for trace synchronization of Ethernet, CAN(FD) and FlexRay recordings, so that they can be meaningfully tested with relation to each other.

Compared to existing synchronization methods, a significantly better accuracy is achieved and additional knowledge about the test process or modifications to the test system are not required.

AutoSPY: Intuitively enlarge diagram view, value range axes and units for more context

The diagram view of the interactive AutoSPY Viewer has been improved:

a) The size of the diagram can be changed intuitively by moving the lower range limit. This method of changing size applies to both individual signals and signal stacks.

b) Diagrams of analog signals include an axis with division and labeling. The enlarged context makes navigation easy in large diagrams. For signal stacks, the associated axis is highlighted when the signal is selected. In the context menu of the axis, the value range can be reset to actual values in the visible time range or in the entire document.


c) In addition to the measured values for the blue and red cursor, the physical unit for the signal values is displayed in a separate column. This makes it easier to identify signals and arrive at correct conclusions.

d) Finally, the possibilities for zooming and navigating in the diagrams have been extended:

  • Ctrl + Mouse wheel: Zoom in time range
  • Shift + Mouse wheel: Zoom in value range
  • Ctrl + Shift + Mouse wheel: Zoom in time and value range
  • Shift + Mouse wheel on axis: Zoom of all signals of the axis in the value range
  • Drag with middle mouse button: Time navigation
  • Shift + Drag with middle mouse button: Navigation in time and value range
  • Shift + Drag with middle mouse button on axis: Navigation of all signals of the axis in the value range

Central depository/deployment of bus, service and A2L caches by TEST-GUIDE


Importing the bus, service and A2L databases for the first time can be time-consuming due to the size of the files and the complexity of the formats.

Through the central depository/deployment of the read-in caches, this process is required much less frequently. Reuses in ECU-TEST therefore access a cache of these files.

After importing into the database, the associated cache is stored in encrypted form in a configured TEST-GUIDE depository. Other ECU-TEST instances can access the cache from there instead of creating separate caches.

AUTOSAR: Support of Classic and Adaptive AUTOSAR releases R19-11 and R20-11 for bus and service communication

The AUTOSAR (AUTomotive Open System ARchitecture) methodology has established itself in many areas for describing modern E/E architectures, especially for on-board network communication.

ECU-TEST now also supports the latest versions of the AUTOSAR system description files (ARXML) for bus (CAN, LIN, FlexRay) and service communication (SOME/IP).
