16 bit Carry Bypass Adder Verilog Code

carry-skip adder (also known as a carry-bypass adder) is an adder implementation that improves on the delay of a ripple-carry adder with little effort compared to other adders. The improvement of the worst-case delay is achieved by using several carry-skip adders to form a block-carry-skip adder. For more information about carry bypass adder you can refer to this wikipedia article.

Basic structure of 4-bit Carry Skip/Bypass Adder is shown below.



The Verilog Code for 16-bit Carry Skip Adder is given below-



Carry Skip Adder Simulation Results:




Cadence RTL compiler is used to synthesize the Carry Skip Adder verilog  code with Uofu standard library.  We got the following schematic after mapping the hdl code to the standard library. This is basically the synthesized view.
