Is there a good o= pen source implementation of a pdp11 for fpga in verilog/vhdl that works wel= l for Unix v6+?

I need to find those free boards :). Those are the best sites, I=E2=80=99ve s= een, too. I=E2=80=99m not entirely sure why I=E2=80=99m wanting to do the fp= ga thing when simh seems to work just fine for everything I=E2=80=99ve ever w= anted to use it for, but having a switch controlled machine that can be put o= n a shelf and taken off and plugged in and run is appealing. Not quite as ap= pealing as having a PiDP-11, but for those of us on a budget, it seems right= somehow! Will=
