first , thanks for your reply .
I understand what you mean.
I just needed some ideas how take the device to its limit.
the FPGA has built-in multipliers, memory etc. and I want to use them also in order get more information. my instructor gave us the idea to create pyramid of inverters , so we can check multiple outputs , how do you think such a structure will compile?
another advice I want to ask is about the most convenient and fast way
to program the fpga. I know VHDL , but I just wonder if there is some other and more convenient way since we don't need to create complicated design . ( i mean is there any exiting blocks that we can just attach together ??) .
thanks. :)
