Many CPLD's are leaded.  Only the high-pin count CPLD/FPGA's are BGA.

Christopher, per favor.

We don't have a board yet, but the code works fine on the Digilent proto
board and the REFLOCK II board.  The latter is Altera rather than Xilinx,
but the same code works on both, but you have to tweak the pin assignments
naturally.

As I said, I am happy to make the VHDL available.   I ought to put under
revision control somewhere.
