CANoe.MOST 7.6
The Development and Testing Tool for MOST Applications
CANoe.MOST combines a wide range of analysis and testing capabilities for MOST systems with a convenient user interface. Besides offering user-friendly interactive analysis of the overall system, its automated analyses and tests are especially useful in boosting efficiency in ECU development and system integration. The network services required for single component tests are provided, including the means for performing a remaining bus simulation.
CANoe.MOST supports all MOST speed-grades
Besides covering the special requirements of the MOST50 or MOST150 system, Vector has also considered the needs of experienced MOST25 users. Thanks to the unchanged user interface and programming interfaces, training effort has been kept very low.
The following table offers an overview of the features of all speed-grades supported by CANoe.MOST. Much of the proven analysis functionality is available, such as Trace, Data and Graphic windows, as well as Registry and Audio windows and the Function Block Monitor. Filter options and the Interactive Generator block for stimulation of the MOST ring were also adapted to MOST50 and MOST150. Services such as AMS and the Application Socket conform to the new specification corresponding to the speed-grade.

For the operation with MOST50 a license for the Optolyzer integration package of Vector and the hardware interface OptoLyzer G2 3050e of SMSC is needed. Interested persons should send an e-mail to the MOST product manager at Vector.
Diagnostic Access to MOST ECUs
The Diagnostic Feature Set of CANoe.MOST lets you conveniently select, parameterize and execute diagnostic services for your ECU. Furthermore, you can view all Diagnostic Trouble Codes (DTCs) in symbolic representation, and you can clear the fault memory as necessary during your tests. You can also integrate the same diagnostic sequences in your test contents in an automated way by scripts.
These functional features are available to you regardless of whether your ECU’s diagnostic access is via CAN, MOST or Ethernet. If the CAN-MOST gateway is not available until later phases, for example, you can execute your diagnostic tests directly over MOST. When the gateway becomes available, you can reuse the test scripts for communication over CAN. It is also possible to obtain access via Diagnostics over Internet Protocol (DoIP) via your ECU’s Ethernet interface, or over the Ethernet channel of MOST150 (MEP).
It is easy to parameterize the Diagnostic Feature Set via ODX or the CANdela database (CDD).
With CANoe.DiVa you can have test cases automatically generated from the same diagnostic description to attain comprehensive test coverage of the diagnostic contents.
Device and System Tests
- Test modules support you in device and system tests by offering a clear sequential flow and well-organized reporting
- Test modules can stimulate the MOST ring as well as wait for reactions of MOST devices, system events or user actions. An input wizard based on the function catalog simplifies creation of the test scripts for you.
- This lets you focus on developing the actual tests in creating test modules. Reporting is performed automatically for the most part. Using the integrated system management modules (Network Master, Power Master and Connection Master) you can start up your ECU, e.g. in individual device tests, in a way that is MOST-conformant.
Compliance Tests
- For customers with a maintenance contract, Compliance Tests used to test for MOST conformance are available upon request.
- Core Compliance tests are currently implemented for MOST specification versions 2V2, 2V3 and 2V4. The so-called source and sink tests are supplied in source code so that you can achieve better transparency and can modify them more easily.
- Also available are Profile Compliance Tests for Connection Management.
- For more precise information about current availability of other tests or implementation of the latest errata sheets please, please contact the Product Manager: MOST@vector.com
Access to Full Bandwidth of the Synchronous Channels
Access to full bandwidth of the synchronous channels
CANoe.MOST enables full access to the synchronous area of MOST. Independent of the configured Synchronous Boundary Control (SBC), all synchronous channels may be transmitted to the PC via USB, or in the reverse direction they may be fed into the ring from the PC. With this access option, CANoe.MOST covers a whole number of application cases in the area of streaming of multimedia data. This is described in detail in the Application Note MOST Synchronous Channel Access.
Device and Remaining Bus Simulation
CANoe.MOST also gives you the infrastructure needed to simulate MOST devices or functions. You can create simulations in CAPL, C++ or Matlab/Simulink and run them in CANoe.MOST. To let you focus on developing the application behavior, CANoe.MOST offers full network services and transport protocols, as well as the system management modules (Network Master, Power Master and Connection Master).
By the integrated bus simulator, you do not need any real hardware at first, to evaluate initial concepts or test scripts.
Gateway Functionality
The pure MOST variant of CANoe.MOST may be combined in any desired way with CAN, LIN, FlexRay and Ethernet variants. You can select precisely according to your needs, which bus systems should be accessed. This also makes CANoe.MOST the right tool for your gateway development. Efficient prototyping, analysis and testing are possible without any problem by access to all buses and the common time base.
In the case of a CAN-MOST combination, for example, you can view the messages of both bus systems in one Trace Window and analyze their interrelationships. With analysis scripts, which then have simultaneous access to the messages and system states of CAN and MOST, you can automatically determine start-up times, measure gateway execution times or verify the signal routing algorithms of your gateway.
