MISRA C ADC available - superseded

[david ward]

This document has now been superseded by MISRA Compliance:2016. The following description is retained for archival purposes.

MISRA is pleased to announce the availability of an additional resource for MISRA C, MISRA C ADC Approved deviation compliance for MISRA C:2004.

MISRA C is intended to be used within the framework of a disciplined software development process. The MISRA C:2004 guidelines (Section 4.3.2) permit controlled deviation from the rules when software safety and/or quality requirements cannot otherwise be satisfied.

It should be understood that a deviation can only be adequately justified when supported by information such as:

• An appropriate reason for the need to raise a deviation;
  
• A description of the extent to which a relaxation of the rule is being introduced;
  
• An argument to support the reasons for the deviation;
  
• Measures which must be observed to ensure safety and/or quality.

MISRA C ADC was a technical note that was a first step in describing the requirements in greater detail. It focused solely on the first of these topics, the common reasons for raising a deviation.
