This page of verilog sourcecode covers HDL code for half adder,half substractor,full substractor using verilog.
A single full-adder has two one-bit inputs, a carry-in input, a sum output, and a carry-out output. Many of them can be used together to create aripple carry adderwhich can be used to add large numbers together. A single full-adder is shown in the picture below. 1-bit Full-Add...

In this way it is possible in this case to assign the result of the adder to two bit vector. Notice how the vector array is formed using the curly bracket {cout,A}. The rightmost part of the vector {cout,A} , which is A in this case forms the LSB. ...
Carry Lookahead Adder in VHDL and Verilog. 4-bit for FPGAs. Contains code to design and test a carry lookahead adder made up of several full-adders cascaded together.
Generally, the full subtractor is one of the most used andessential combinational logic circuits. It is a basic electronic device, used to perform subtraction of two binary numbers. In the earlier article, already we have given the basic theory ofhalf adder & a full adderwhich uses the binary...
Answer to: Implement the carry output of a full adder using a 3 to 8 decoder. By signing up, you'll get thousands of step-by-step solutions to your...
The carry output, which is the carry overflow from the addition, is designated as (C21, C20). Table 1. The truth table of the dual-rail encoded asynchronous two-bit full adder (TFA) w.r.t R0H. The output expressions of the dual-rail encoded TFA, corresponding to R0H, are given ...
