Verilog Code For Serial Adder Subtractor

GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Sign up An 8-bit adder-subtractor made of full adders in Verilog. Testbench Code- 4bit Adder `timescale 1ns / 1ps ///// // Company: TMP // Create Date: 08:15:45 // Module Name: 4bit Adder // Project Name: 4bit Adder. Verilog program for Half Adder Verilog program for Full Adder Verilog program for 4bit Adder Verilog program for Half Substractor.

You know how to do addition using step-by-step. Always, the carry value is add to next step and the sum value is written to result. I tried to tell these in a picture:

If we want to write an algorithm for these, how to do this?

Verilog code for the algorithm:

1. Full Adder Code (We Need! You can use another codes like the previous blog post):

2. Four Bit Adder Code:

Bonus – Test Code:

Here, test result 🙂

This repository contains behavioral code for Serial Adder.The following individual components have been modeled and have been providedwith their corresponding test benches:

• Parrallel Input Serial Output Shift register (PISO) (piso.v)
• D Flip Flop (d_flipflop.v)
• Full Adder (full_adder.v)

File serial_adder.v is the master node, the corresponding testbench isserial_adder_tb.v. To compile and visualise the waveforms (using iverilogand gtkwave), follow these steps:

• Install iverilog and gtkwave using the instructions given here.
• Clone this repository using the command git clone https://github.com/RJ722/serial-adder-verilog.
• cd serial-adder-verilog
• iverilog -o serial_adder.out serial_adder_tb.v
• ./serial_adder.out
• gtkwave serial_adder_tb.vcd # Visualise waveforms

For changing the input values to the adder, please make changes in serial_adder_tb.v.
