In this case, you'd get better results if you specified a more
specific arch=, rather then let it make the generic LPM devices.
The problem here is that there are just some code generator functions
missing for the architecture you are targetting.
It seems to me that the arch= only targets Xilinx virtex parts. If O'm
not using those devices, then i have to use arch=lpm, yes?
