Logic Gates and the Ripple Carry Adder
 
09:25
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.

Verilog Tutorial 5 -- Ripple Carry Full Adder
 
15:56
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 Recommend viewing in 720p quality or higher. 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.

When two 8-bit numbers A7....A0 and B7.....B0 in 2’s complement representation (with A0 and B0 as the least significant bits ) are added using a ripple-carry adder, the sum bits obtained are S7….S0 and the carry bits are C7….C0. An overflow is said to have occurred if (a) the carry bit C7 is 1 (b) all the carry bits (C7….C0) are 1 (c) (A7B7 .(𝑆7) ̅ + (𝐴7) ̅ . (𝐵7) ̅ .S7 ) is 1 (d) (A0 .B0 . (𝑆0) ̅ + (𝐴0) ̅. (𝐵0) ̅.

Carry out and overflow in binary addition

Binary addition in two’s complement form with overflow detection. Just because a carry out is 1 does not mean that there was an overflow. For the last bits for two numbers xor carry in with carry out to determine overflow.

Digital Electronics: Overflow, Overflow Detection and Underflow
 
28:29
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. This video is part of materials on modules taught by Derek Molloy, School of Electronic Engineering at Dublin City University, Ireland: http://www.eeng.dcu.ie/~molloyd/
