There had been a discussion about that feature back in June of last year 
  on this mailing list. Here is a link to the achieve of that:

http://sourceforge.net/mailarchive/forum.php?forum_name=myhdl-list&max_rows=25&style=ultimate&viewmonth=200706

Jan had written some background information about the intention of intbv 
there in connection with the wrap around functionality.

This might be a good question to be answered on the FAQ page.
