See http://www.ultratechnology.com/chips.htm

I used Dr. Ting's P16 (http://www.ultratechnology.com/p16vhdl.htm) as a 
test VHDL source to compare free software from Xilinx and Altera. The 
results were better than I had expected (faster than 50 MHz before any 
optimization) and though they required larger chips than I wanted to 
use it is probably easy to make it much smaller by changing the design 
to make use of the RAMs in the FPGAs.
