You can create HW multiplier using only NOR+AND elements. It will consume a lot of silicon, but will work fast enough. BTW, most FPGAs have HW multiplier prebu

You can create HW multiplier using only NOR+AND elements. It will consume a lot of silicon, but will work fast enough. BTW, most FPGAs have HW multiplier prebuilt block, because you will loose lots of flip-flops or LUTs (or both) implementing one yourself.
