he use of multicore systems brings extra complexity to software behavior, and as a result to the certification and verification activities that must be performed to provide sufficient design assurance. As multicore systems were not used in avionics when DO-178C was released, DO-178C itself includes no guidance on certification concerns for multicore systems. This was addressed by the CAST team in CAST-32A, which is due to be superseded by AMC/AC 20-193.
