C&S group has a wide range of experience in the area of communication protocols for networked controllers particularly based on Controller Area Network CAN and related transceivers as well as higher layers.

For some years these experiences have been expanded to the fields of testing and certification methodology. Significant contribution has been done to establish the ISO standard on CAN Conformance Testing ISO CD16845 - currently final draft status. Since 1998, C&S is the responsible partner for test specification and implementation on Low Speed CAN and later also on High Speed CAN Transceivers within a group of car manufacturers such as Audi, BMW, Daimler, Ford, PSA and Volkswagen.

GIFT - Generalized Interoperable Fault Tolerant CAN Transceiver - is an international group consisting of automotive and semiconductor manufacturers, guiding CAN transceiver interoperability issues to ISO standard. C&S acts as a chairman of this group.

CAN Transceiver Conformance Tests - Principle and Methods

The transceivers are tested in their entirety of a defined number of transceivers in a constant standard net environment, the so called Standard Net.

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 to test have to interoperate not only with themselves in a "Homogeneous Network" but also with others in "Heterogeneous Networks".

Many implementations have been tested so far. Some have been released for our list of tested products:

Tested Products - Low Speed CAN
Tested Products - High Speed CAN
