Hello, as GHW is a binary format, there is not grammar for it. You have to look at the sources to understand the format. I am not sure that a grammar is the best way to describe this format (for the same reason, I suppose no one has written a grammar for mp3).
GHW supports all the vhdl types, including floating point types.
