You can tell the synthesizer and P&R to focus on speed more then size, there are various options on both sides for that sort of fine tuning. If your FPGA is relatively empty I doubt you'll get much of a boost, but you never know. > For now, I'll just stick to 200MHz with XST. >=20 >=20 > Synplify seems to be generating faster designs.

Import the edf created by synplify into ISE and run the design there to get to bitgen.
