Hi, I'd like to put suggest something: There is a gpl opensource
soc framework called grlib at It has a sparcv8 cpu
at its heart and supports many configurations/boards, spartan, virtex,
cyclon and
actel devices (also asic targets..). All the peripherals to build up
a capable platform  are there, s/sd/ddr memctrl, ethernet etc.
Also a nonintrusive debug  support unit with ethernet link etc.
All around an AMBA bus. Now I wonder:
The ursp2 is supplied in verilog at gnuradio,
the analog expansion boards can be ordered at etus or build
self, the analog boards dont seem to be that complex... So why not
add the usrp2 verilog parts as amba-peripherals  to the grlib
framework and then run the whole system on a fpga? I'd be able
to help here also...
