Friends -
I took a whack at laying out a Xilinx Spartan3-FT256 in PCB. I posted my results so far at http://recycle.lbl.gov/~ldoolitt/ft256/ It's set up for a 6-layer board, and routes all 184 non-power pads out to traces on a 0.5 mm grid.
I welcome constructive criticism, especially in the context of (relatively) high speed design. My interest in this chip is for designs running at about 100 MHz.
