Write VHDL code for a 16-bit Carry Save Multiplier. Instructions are:

Also, the figure below showing a 16-bit carry save multiplier:

I need to design a 16-bit carry save multiplier. I have already wrote all other components. I am using half-adders and full-adders for implementation. Thank you!

Carry Save Multiplier The multiplier has the following features: e Functions: - Multi-bit multiplication. Parameters The output length, in bits. To be called n. Inputs - A (n/2 bits): First factor. B (n/2 bits): Second factor. Outputs Product (n bits): Product. Note that this is twice as long as the factors. The carry save multiplier must be structural Note that the rightmost adder could be a half adder, as the carry in is set to zero. The use of the and operators is not allowed Carry Save Multiplier The multiplier has the following features: e Functions: - Multi-bit multiplication. Parameters The output length, in bits.
