Hi
I have designed a board with XC6SLX45-2FGG484I and ISE would not recognize the part, it would say an unknow device, I have checked everything and it seems the config schematics is ok, I assigned a spartan6 device bsdl file from C:\Xilinx\14.7\ISE_DS\ISE\spartan6\data folder, so the impact would let me read device id etc..
when I read device ID I would get something very similar, only two bits that should be 1 are 0, do you have any Idea what might have caused it or what's the problem?
