Hi John, I started a backport branch of the 7.1 library in http://casper.berkeley.edu/svn/branches/backport_to_7_1/ If you check that out with SVN you'll find the FFT block there uses the new (pink espresso style) reorder block. Eventually I'll expose a setting so you can choose between the logic map and ROM based map, but I haven't done that yet. Hope this helps, Glenn
