A(M)C 20-193 vs. CAST-32A: What the change means for your DO-178C Multicore project

AMC 20-193, EASA’s official guidance document for certification of multicore software and hardware, was recently released on 21^st January 2022.

Until now, certification applicants for multicore software and hardware for ED-12C/DO-178C or ED-80/DO-254 projects followed CAST-32A guidance. For applicants certifying under EASA, AMC 20-193 has now superseded CAST-32A. It is expected that the FAA will release its AC 20-193 guidance soon, which is expected to be almost identical to AMC 20-193.

We’ve spent some time reviewing the new guidance in order to highlight the differences between AMC 20-193 and CAST-32A. In this technical webinar we explore how changes to the following areas can affect your project:

• Dynamic allocation of software execution
• Simultaneous multithreading
• Exemptions
• Integrated Modular Avionics (IMA)
• Other definitions and clarifications
• Mitigation of changes to critical configuration settings
• Use of simulators
