We offer:
Conformance test of your CAN High-Speed transceiver.

These tests were defined in the framework of the GIFT/ICT group and are complementary to the test cases defined in ISO11898-2/5. They are classified in different groups depending on the capabilities supported by the transceiver:

  1. capabilities equivalent to the TJA 1041
  2. capabilities equivalent to the TJA 1040
  3. capabilities equivalent to the TJA 1050 with consideration of low power modes
  4. capabilities equivalent to the TJA 1050 without consideration of low power modes.

We offer:
Conformance tests of your CAN High-Speed transceiver with Selective Wake-up Functionality.

The selective wake-up functionality is applied for partial networking to save energy and reduce accordingly the CO2 emissions.

Partial networking is a method intended to make it possible for a node or for a cluster to be woken individually by means of dedicated and predefined CAN messages instead of woken by any activity on the bus as defined in ISO11898-5 for conventional CAN High Speed Transceivers.

Since the beginning of 2010 an international working group called SWITCH (Selective Wake-up and Interoperable Transceiver in CAN High Speed)  managed by C&S Group has been working to make partial networking for CAN bus systems an environmental and commercial success. The outcomes documents specified in the framework of this group are currently in the ISO process.

We offer tests according to:

  • The (NWIP) ISO 16845-2 which defines the conformance tests for the ISO/CD 11898-6
  • Single device and system interoperability tests according to the OEM hardware requirements for partial networking (v 2.1)

We offer:
Conformance test of your Fault Tolerant CAN Low-Speed transceiver.

These tests were defined in the framework of GIFT/ICT and verify the correct behavior of your transceiver with the aim to increase the probability of interoperability significantly. The CAN low-speed transceiver tests are only carried out on request and require a longer leadtime.

Do you want to test with us?

Then we need your support so that we can adapt your transceiver smoothly to our test system. We have compiled a document for you, where you can check the relevant requirements.

And then please read under Best Practice, what are the benefits and what you can expect from us!

The principle behind our CAN transceiver testing.

CAN Physical Layer Conformance Testing intends to ensure correct interoperation of CAN transceivers in complex CAN networks that use devices from different suppliers.

That is one reason why we test your CAN transceiver in our so-called standard networks whose structure is defined exactly in the test specifications for complex CAN transceivers. A further reason for the development of the test systems as networked systems is that your transceiver is part of a CAN node – and in the CAN transceiver specifications for a networked system a minimum number of CAN nodes is defined.

We test the conformance of the transceiver thereby under terms that reflect its future application conditions.

Test conditions have been derived by an international group of automotive OEMs and semiconductor suppliers, the GIFT/ICT group.

The GIFT (Generalized Interoperable Fault Tolerant CAN Transceiver) / ICT (International Transceiver Conformance Test) working group was formed in 1999 and managed by C&S Group in order to establish vendor-independent, harmonized specifications for the properties of CAN transceivers and specifications for their conformance tests. Its first aim was the draft and creation of a specification of a CAN transceiver module in such a way, that technical interoperations of devices from different manufacturers were possible.

The test systems.

The test systems consist of a well-defined standardized network (Standard Net), where the ECUs communicate under various system conditions. A supervisor software controls system states and test sequences. CAN communication is supervised and controlled by calibrated measurement equipment.

The Standard Net consists of a fixed number of identical nodes, either equipped with the devices under test only, or in a given combination with other devices. So the devices under test have to interoperate not only with themselves in a “Homogeneous Network” but also with others in a “Heterogeneous Network”. The tests in the network are executed for both homogeneous and heterogeneous transceiver composition.

The behavior of a transceiver can be represented by an asynchronous state machine. The transitions, from one state to another, represent reactions to certain events. These tests verify the proper behavior under different conditions like:

  • ground shift, loss of ground and loss of power
  • wake-up conditions and operating mode changes from normal to low power and vice-versa
  • disconnection of termination; CAN bus interrupted; CAN buses shorted between each other, or to ground, or to battery, etc.

During the tests the behavior of your CAN transceiver as well as the entire network is compared with the expected behaviors.
The test data – including raw data – are stored for later analysis and to make the test reproducible. The processed data are given to you with your test report.
