I am having to build a multisim circuit for
class that can that takes an unsigned 4-bit input number N and generates an unsigned
8-bit output NSQUARED that equals the product of N * N. example, input N is 1001 (9),

 the output NSQUARED is 01010001 (81). The smallest inputis 0000 (0). The largest input is

1111 (15). Maybe AND gates and etc. not sure where to start, Any assistance would be great.

Below is a schematic where I started, as you can see I need other components, this thing is

 too large.

You might find some circuit recommendations in a different group.   I recommend giving it a try based on some basic digital logic circuits and let the forum know what type of help you need (with respect to Multisim).  

I would first try the generic digital TIL family as they will exhibit mostly ideal behavior for this type of circuit.
