Amit,
you will not fnd a multiplier, nor even an adder. The chip has lots of
wide AND gates that can be ORed together, and that's the (very low)
level of abstraction you should use to design. Back to basics (or is
it forward to basics for you ?).
Good exercise in logic design, and in logical thinking.
