Indeed!  Galois maintains a language called Cryptol.  Almost all tools for
this language, including an FPGA compiler that produces HDL, are written in
Haskell.  It is not open source, nor is it free as in beer, but there is a
free academic version without FPGA support.

As for Lava and the Xilinx version, I am not really sure how actively it is
being developed.  Perhaps someone else here knows?

You're going to design something like that with an FPGA in it?  :)

For a simple enough design, it can be useful to write specs in Haskell and
then translate them to HDL by hand.  I believe someone on this list had a
particularly successful experience doing that :).
