Analysis and Testing

LIN is a single wire system. The protocol does not provide dedicated error notification mechanisms. Therefore analysis and test tools are required that allow to perfectly safeguard a LIN network or ECU. Vector's LIN tool chain convinces with analysis functions that allow to recognize and interpret easily any LIN protocol error and provides test functions to stimulate any kind of LIN errors.

Tools
CANalyzer is the comprehensive software tool with intuitive operation for analysis and stimulation of network communication. It is used to check whether and what type of communication is occurring on the network. It can also be used to send or log data.  The Option .LIN is used to  monitor network states and protocol errors and to interpret them in a simple way. The LIN communication can be logged in different file formats to perform offline analysis.
CANoe is the comprehensive software tool for development, test and analysis of individual ECUs and entire ECU networks. It supports network designers, development and test engineers at OEMs and suppliers throughout the entire development process – from planning to system-level test.

Master Conformance Testing with CANoe

The LIN Master Conformance Tests according to ISO 17987:2016 and LIN 2.x are not implemented in CANoe .LIN because they are rarely performed. The reason is that you have to exchange the application with a specific test application which allows to perform the tests. Therefore, the LIN Master protocol functionality is checked during testing the application.

To ensure correct operation of LIN Master ECUs, CANoe offers a number of possibilities to assemble a monitoring LIN Master test. E.g. header times, baud rates or schedule tables can be monitored. An example configuration included in CANoe shows you how to set up an observing LIN Master test.

Diagnostics and Flashing

The following software products support vehicle diagnostics for LIN.

CAPL-on-Board with VN1630A and VN1640A
This special run mode for CAPL network nodes enables time- and performance-critical simulation models to be run directly "on-board" on the network interface.
 
Benefits:
  • Less jitter / less timer delays
  • Less PC utilization
High Performance Interfaces: VN8900 Family and VT6000 Family
The VN8900 and VT6000 real-time systems consist of these 2 components:
 
1. User PC
  • As front-end for operation of graphical user interface of CANoe
  • As host for the logging of data and test results
2. RT server as runtime environment
  • For the remaining network simulation and environmental simulation
  • For execution of test scripts

Benefits:
  • User interface and simulation part are isolated from each other. For this reason other PC tasks, such as compiling, virus checking, Outlook, etc., do not adversely affect the network simulation and measurement.
  • System configurations can be easily scaled based on user-defined requirements, e.g. monitoring, soft real-time simulation, real-time simulation.
  • The same model can be run both in a real-time environment and in a conventional environment.
  • The model can be run in the real-time environment with higher accuracy and lower jitter and is thus more deterministic.
  • The workflow is the same as the standard CANoe workflow.
