I am not an xcos user, but what about the following proposals:

  * use several MUX whose outputs are branched to another MUX. The
    output of this last one should be equivalent to the one of a big
    MUX. Shouldn't it?
    This "2-layer MUX set up" allows to "concatenate" up to 31*31 = 961
    input channels, and to "split" the positioning of blocks of inputs
    in a more manageable way than with a single huge MUX block.
    Couldn't a MUX be considered as a columns concatenator, each column
    being a separate signal? So, concatenators might be nested in this way.

  * To build a big DEMUX, a somewhat symetric proposal:
      o from the single input, extract some ranges of channels with one
        or several EXTRACTOR blocks, with at most 31 bundled channels in
        the single output.
      o put a DEMUX after each EXTRACTOR, to split their channels as as
        many outputs.

These naive proposals should be tested. The 2-layer MUX setup looks to 
work when the final output is connected to a simple scope: then there 
are as many curves as primary inputs.


Could this match your requirements?

Regards
Samuel
