Sorry that's not that helpful, can you expand on this. As of right now what I'm
interpreting is that any type that contains the keyword array() in vhdl should
be translated into an empty array? Well actually that's not what I'm
understanding, I'm unable to reach any useful conclusions from what you've
instructed here.
