This paper focuses on the implementation and simulation of 4-bit, 8-bit and 16-bit carry look-ahead adder based on Verilog code and compared for their performance in Xilinx.

In this paper, design of 32-bit parallel multiplier is presented, by introducing Carry Save Adder (CSA) in partial product lines. The multiplier given in this paper is modeled using VHDL (Very ...
