MISRA C:2023 – The rules for the development of safety-critical software


Date: On demand
Duration: 1 day, 9:00 am – 5:00 pm
Location: ONLINE
Language: English
Referent: Ralf Schneeweiß
Early Bird: N.A.
Price: N.A.


In this one-day seminar learn about the objective of MISRA rules for error prevention in safety-critical software. In addition to the practical applicability of the rules, the integration of rule checking in the development process will be discussed. How to achieve MISRA conformance?

Target group

  • Software developer
  • Technical project manager


  • Any C Compiler that is compatible with ANSI C89 or ISO C90 can be used. For MISRA C:2023 the compiler may also support C99 or the C11 standard, which is the case for most compilers in use today. The recommended platforms are Windows, MacOSX, UNIX or Linux systems.
  • Course participants should master the C programming language and simple data operations on the system they use. A selection of rules are explained with real program examples.


MISRA C:2023 guidelines (PDF) licensed for each participant.


In this course, the development of safety-critical software written in ANSI/ISO C in the variants C89/90, C99 and C11 for embedded systems in the automotive field is covered. The possible reasons for failure are analysed and discussed. The typical failures occurring in the implementation with standard C are classified and associated to the MISRA rules. Beside the work on the rules, the structure of the MISRA Rule Document from 2023 is discussed. The rules themselves are covered in detail and the documentation requirements necessary to prove the compliance with the rules are discussed.
