The parameter data item file must be verified together with the executable object code, or else it must be tested for all possible ranges of the parameter data items. DO-330 "Software Tool Qualification Considerations", a new "domain independent, external document", was developed to provide guidance for an acceptable tool qualification process ...
Given ASIL is a relatively recent development, discussions of ASIL often compare its levels to levels defined in other well-established safety or quality management systems. In particular, the ASIL are compared to the SIL risk reduction levels defined in IEC 61508 and the Design Assurance Levels used in the context of DO-178C and DO-254. While ...
Partitioning Aspects in DO-178C/DO-278A; Relationship Between Regression Testing and Hardware Changes; Cache Management; Usage of Floating-Point Arithmetic; Service Experience Rationale for DO-278A; Independence in DO-178C/DO-278A; Parameter Data Items and Adaptation Data Items; Clarification on Single Event Upset (SEU) as It Relates to Software
Various standards suggest different levels, e.g. Software Levels A-E in DO-178C, [4] SIL (Safety Integrity Level) 1-4 in IEC 61508, [1] ASIL (Automotive Safety Integrity Level) A-D in ISO 26262. [2] The assignment is typically done in the context of an overarching system, where the worst case consequences of software failures are investigated.
The Advisory Circular AC 20-115( ), Airborne Software Development Assurance Using EUROCAE ED-12( ) and RTCA DO-178( ) (previously Airborne Software Assurance), recognizes [1] the RTCA published standard DO-178 as defining a suitable means for demonstrating compliance for the use of software within aircraft systems.
It is a misunderstanding that by purely syntactic rearrangements of decisions (breaking them into several independently evaluated conditions using temporary variables, the values of which are then used in the decision) which do not change the semantics of a program can lower the difficulty of obtaining complete MC/DC coverage.
The Certification Authorities Software Team (CAST) is an international group of aviation certification and regulatory authority representatives. The organization of has been a means of coordination among representatives from certification authorities in North and South America, Europe, and Asia, in particular, the FAA and EASA.
LDRA is a contributor to several industry standards, including DO-178C, [18] MISRA C [19] and MISRA C++. [20] Additionally, LDRA is an Industry Partner [21] for the CERT C Secure Coding Standard [22] produced by the Computer Emergency Response Team at Carnegie Mellon's Software Engineering Institute.
