Per the DO-178C definition, it is not possible to demonstrate “determinism” for multicore systems based due to their inherent non-deterministic nature. Accordingly, A(M)C 20-193 utilizes the DO-297 definition of determinism; “the ability to produce a predictable outcome” where “the outcome occurs in a specific period of time with repeatability”.
We believe this can be achieved if sensible design decisions are made. We discuss this in the Software Architecture Considerations white paper in MACH178 Foundations. Your approach to demonstrating WCET in a multicore system should be agreed with your certification authority in advance. You can find information that’s helpful for achieving this in the WCET Considerations white paper in MACH178 Foundations.
