And this is what bothers me _a lot_. If the device is not fully
documented (as in, if I cann not predict its behavious when I load a
paritcular configuration file)m, then I can't know excatly what it is
doing to my design. So when my deisgn doesn't work, I am left trusting
that the manufacutrers tools and devices both work properly . Which is

Actually IIRC there was one device that looked possible (Xilinx XC6000
series). It had very simple logic blocks and it was fully docuemtned. The
only problem was it weas discontinued before the UK distributors got any
of them...
