    For automotive software the ISO 26262 is the equivalent to RTCA DO-178 in avionics. ISO 26262 highly recommends that ASIL C and D-classified systems utilize semiformal and formal v…

    That is because the formal method supplement of the DO-178C is RTCA DO-333. There you have about a hundred pages concerned with the application of formal methods.

    And what the OPAL functional language [1] did since the mid 80s. Though the concept there is expanded from simple reference counting by additional static analysis during compile ti…

    No, a domain-consistent all-different propagator such as the one desccribed in [1] is sufficient to determine a valuation domain for a Sudoku puzzle without any search. Of course t…

    Yes, but even better there is the global constraint geost [1] which is specifically for this purpose in k-dimensions; see also [2] for a more detailed presentation. Unfortunately, …

    Well, since both are implementations of the Modelica standard I would guess they are pretty much the same, though I do not know MapleSim or your problems with it.

    This is simply a different view to model systems such as can be done in Simulink. Simulink has a (differential) equation-centric view whereas Modelica (of which SystemModeller is a…
