Road vehicles - Functional safety - Part 11: Guidelines on
applications to semiconductors
1 Scope
This document is intended to be applied to safety-related systems that include one or more
electrical and/or electronic (E/E) systems and that are installed in series production road
vehicles, excluding mopeds.
This document does not address unique E/E systems in special vehicles such as E/E systems
designed for drivers with disabilities.
NOTE: Other dedicated application-specific safety standards exist and can complement this document
or vice versa.
Systems and their components released for production, or systems and their components already
under development prior to the publication date of this document, are exempted from the scope
of this edition. This document addresses alterations to existing systems and their components
released for production prior to the publication of this document by tailoring the safety lifecycle
depending on the alteration. This document addresses integration of existing systems not
developed according to this document and systems developed according to this document by
tailoring the safety lifecycle.
This document addresses possible hazards caused by malfunctioning behaviour of safety-
related E/E systems, including interaction of these systems. It does not address hazards related
to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion,
release of energy and similar hazards, unless directly caused by malfunctioning behaviour of
safety-related E/E systems.
This document describes a framework for functional safety to assist the development of safety
related E/E systems. This framework is intended to be used to integrate functional safety
activities into a company-specific development framework. Some requirements have a clear
technical focus to implement functional safety into a product; others address the development
process and can therefore be seen as process requirements in order to demonstrate the capability
of an organization with respect to functional safety.
This document does not address the nominal performance of E/E systems.
This document has an informative character only. It contains possible interpretations of other
parts of GB/T 34590 with respect to semiconductor development. The content is not exhaustive
with regard to possible interpretations, i.e., other interpretations can also be possible in order to
fulfil the requirements defined in other parts of GB/T 34590.
34590.9-2022, whenever applicable, can be used for the design of the safety mechanisms during
the development of the IP.
EXAMPLE 1: Bus “fabric” with built-in bus supervisors including fault detection and notification logic
(e.g., interrupt signals).
EXAMPLE 2: Voltage regulator with monitoring (under-voltage and over-voltage detection), protection
(current limit or thermal protection) and self-diagnostics (monitoring and protection circuit built-in self-
Alternatively, the IP can be developed with no assumed safety requirements or specific safety
mechanisms to detect and control faults.
EXAMPLE 3: Bus "fabric" without built-in bus supervisors or error reporting logic.
EXAMPLE 4: Voltage regulator without monitoring, protection or built-in monitoring or protection
circuit diagnostics.
Safety analyses defined in GB/T 34590.9-2022 Clause 8 can be applied to the IP. A qualitative
safety analysis, and in some cases a quantitative analysis, can be provided to the IP integrator
to justify the capabilities of the safety mechanisms to control given failure modes or to provide
information on failure modes and related failure mode distribution. Similarly, a dependent
failure analysis can be provided to demonstrate required independence or freedom from
NOTE 3: The IP supplier includes example information concerning failure mode distribution in the
safety analysis results, based on specific implementation assumptions. Documentation related to safety
mechanisms can be provided with other safety-related documentation for the IP. This information can
also be combined into a single safety manual or safety application note as described in 5.1.11 (for digital
components), 5.2.6 (for analogue or mixed signal components), 5.3.6 (for PLD) and 5.5.6 (for
NOTE 4: The base failure rate depends on the actual implementation, including the technology, of the
IP into the integrated circuit and the use condition of the integrated circuit, as described in 4.6. So, the
base failure rate can only be provided as a reference to the IP integrator who is responsible for
recalculating the failure rate according to the actual use case.
NOTE 5: This information can be included within existing documentation (e.g., integration guidelines,
technical reference documents, application notes).
The IP integrator can request additional information from the IP supplier in implementing safety
requirements. The IP supplier can support the request by providing information concerning
measures used to avoid systematic faults, as well as safety analysis results. Safety analysis
results can be used to support the evaluation of hardware metrics for the integrated IP, as well
as to demonstrate freedom from interference and independence.
Since the IP will be integrated into a safety-related design, consideration of coexistence is
