Our 4-cpu system is running on fpga, but is planned to be fabbed on a 0.13 line.
We use an off-the-shelf FPGA development board based on the Virtex2-6000 fpga.
Leon3 and the GRLIB IP library is fully portable and you can use any of
the major FPGA types (Actel, Altera, Lattice, Xilinx). I have seen cheap
(~ $800) boards with an Virtex4 LX60 from Avnet where you can easily fit
four or more leon3 cpus. There are also several dedicated leon2/3
development boards available from Pender Electronics (www.pender.ch),
including a low-cost spartan3-1500 board which will fit two cpus.
