"The blocks in Data Acquisition Toolbox that support Simulink are available only for data acquisition devices that can be used with the legacy interface."
As the legacy interface is only for 32 bit MATLAB and as of R2016a there will not be any more 32 bit MATLAB, I wonder what they will do to provide data acquisition blocks for Simulink? It would be a nuisance to have to code it all in terms of MATLAB Blocks or Interpreted MATLAB Blocks.
