Padraic Edgington

This video follows on from previous videos about truth tables and Karnaugh maps. It hints at how truth tables and K-maps can be used in circuit design. It covers some well known logic gate combinations including NAND, NOT and XOR, and how logic gates can be combined to make a half adder, then a full adder and ultimately a ripple carry adder capable of multi-bit binary addition.

This video is an introduction into 4-bit Binary Addition. It discusses the concept of binary addition and extends on a previous video that demonstrates how to create a half adder and full adder. It shows how to cascade full adders together to create the 4-bit adder circuit and discusses the use of the 74HC283 4-bit full adder with fast carry. This video is part of an introductory module on Digital Electronics that takes place at Dublin City University (DCU), Ireland. See: www.eeng.dcu.ie/~molloyd/EE223/

For large adders the complexity of the carry-lookahead circuitry increases rapidly. In this case smaller carry-lookahead adder blocks can be combined in a hierarchical fashion to obtain a tradeoff between speed and complexity.

In this Verilog tutorial, we implement two versions of a 4-bit Ripple Carry Full Adder using Verilog. One version is implemented using built-in Verilog gates, and the other version uses a standard approach.
Complete example from the Verilog tutorial: http://www.edaplayground.com/s/example/368

About EDA Playground:
EDA Playground is a web browser-based integrated development environment (IDE) for simulation of SystemVerilog, Verilog, VHDL, and other HDLs. EDA Playground is a free web application that allows users to edit, simulate, share, synthesize, and view waves for hardware description language (HDL) code. It is the first online HDL development environment and waveform viewer for the semiconductor industry.
EDA Playground homepage: http://www.edaplayground.com
Engineers have used EDA Playground for:
-- creating hands-on training for students
-- demonstrating best practices to other engineers
-- asking SystemVerilog questions on StackOverflow and other online forums
-- testing candidates' coding skills during technical interviews (phone and in-person)
-- quick prototyping -- trying something before inserting the code into a large code base
-- checking whether their RTL syntax/code is synthesizable
EDA Playground is actively seeking partners to integrate additional EDA tools. Future tools will include formal verification, linting, and analog and mixed-signal support.

In this video I will look at the problems that can arise in unsigned and signed systems with overflow and underflow, which is where our system goes beyond its physical limitations. I will look at how you can detect that overflow is occurring in a digital system and how you can design a logic circuit to detect its occurrence. The video then describes underflow and finally, presents a few interesting questions with solutions.
