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.
2 Normative references
The following referenced documents are indispensable for the application of this document. For
dated references, only the edition cited applies. For undated references, the latest edition of the
referenced document (including any amendments) applies.
GB/T 34590.1-2022, Road vehicles - Functional safety - Part 1.Vocabulary (ISO 26262-
1.2018, MOD)
3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T 34590.1-2022
apply.
4 A semiconductor component and its partitioning
Random hardware faults and failure modes of an integrated circuit are linked together as shown
in Figure 3 below.
A failure mode is described at a level of detail commensurate with the safety concept and the
related safety mechanism.
5 Specific semiconductor technologies and use cases
Memory fault models can vary depending on the memory architecture and memory technology.
Typical fault models of semiconductor memories are shown in Table 29.The listing is not
exhaustive and can be adjusted based on additional known faults or depending on the
application.
One of the key aspects for the safety analysis of analogue elements is the proper identification
of the granularity of the analysis. On one hand, a lower level of granularity is beneficial as it
0.2% FSR.
Annex A
(informative)
Example on how to use digital failure modes for diagnostic coverage evaluation
The following is the DMA use case considered in this example.
For the evaluation, the failure modes are further elaborated.
Annex B
(informative)
Examples of dependent failure analysis
The microcontroller component described in Figure B.1 is used to illustrate the dependent
failure analysis methodology for a digital component.
Annex C
(informative)
Examples of quantitative analysis for a digital component
The following is an example of a quantitative analysis using the method described in 5.1.7.
