QUOTE (Michael_Aivaliotis @ Dec 7 2008, 04:15 AM) Shift-registers adds extra constraints to the layout algorithm. Perhaps this may be leading to wires bending all around. But, again, this could just be one of the many possible reasons ( including glitches in the algorithm.) Two things worth checking are : 1. Try with Manual Tuning with LayoutQuality set to max and keep the horizontal compactness to 2nd or 3rd position. 2. (Just for confirmation,) remove the shift register (or replace with tunnel) and see if that's any better. -Regards, Anand
