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 ...
MIL-STD-498 standard describes the development and documentation in terms of 22 Data Item Descriptions (DIDs), which were standardized documents for recording the results of each the development and support processes, for example, the Software Design Description DID was the standard format for the results of the software design process.
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
The Software Level, also termed the Design Assurance Level (DAL) or Item Development Assurance Level (IDAL) as defined in ARP4754 (DO-178C only mentions IDAL as synonymous with Software Level [2]), is determined from the safety assessment process and hazard analysis by examining the effects of a failure condition in the system. The failure ...

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 ...
