match line faults. Thus, together with other CAN controllers, fault-tolerant bus sys-
tems are built. The concept of this transceiver was well received.
A working group was set up, which had set itself the task of developing in two
projects a general specification of a fault-tolerant transceiver and the tests for this
transceiver. The working group is composed of automotive and semiconductor man-
ufacturers. Chairman of the working group is still the C&S group (see Table 6.2 ).

• The project GIFT had the objective of specifying and standardizing a fault-tole-
rant CAN low-speed transceiver to ensure interoperability of CAN modules with
transceivers from different manufacturers. The specification is now published as
ISO 11898-3 standard (see Sect. 6.2.1).
• Within the project ICT, the conformance tests 5 for this standard were developed.
The C&S group, 6 one, at this time, already-established test house for CAN chips,
in cooperation with the GIFT/ ICT partners, was responsible for the specifica-
tion of TCs and their implementation in a test system. The test specification
was published in 2001 under the title International CAN Low-Speed Transceiver
Conformance Test.

The group continued to work after completion of the projects, and expanded the
standard ISO 11898-2 to ISO 11898-5 (see Sect. 6.2.1).
In this standard also, the C&S group was responsible for the specification and
implementation of TCs, in cooperation with the GIFT/ICT partners. The specifica-
tion is titled CAN High-Speed Transceiver Conformance Test.

Test Method and Test Principles

At the beginning of the development of a test specification and a test system, de-
cisions must be made about the principle way of implementation in terms of test
method, test setup and determination of the TCs.

5 A conformance test verifies the conformity of the features of a test object with the requirements
that are put to the test object. These requirements are described in the specification of the test
object.
