Hi Steve,

I have prepared a set of patches to extend the functionality related
to unpacked arrays [1] along with tests [2]. If I have not missed
anything, now I should be able to continue my work on vhdlpp.

Casting between dynamic arrays and vectors currently is realized with
Icarus-specific VPI functions ($ivl_darray_metho$[from/to]_vec).
Ideally, it should be done using type casting, as it was proposed
earlier, but I would rather implement it a bit later.

I had some doubts if it is enough to simply add a case statement to
support dynamic arrays of logic type [3]. The output vvp code uses
%store/dar/vec4 and %load/dar/vec4, so I assume it should be fine.

Regards,
Orson
