Instead of going with silicon-based switching (ie: transistors) this 4-bit adder uses ... in the project box. Sure, simulators are a great way to understand building blocks of logic structures ...

making it feasible to construct any type of complicated logic IC reliably. In addition, more complex functional units such as a full adder, and MUX and DEMUX circuits are successfully demonstrated ...

The simplest approach to design an adder is to implement gates to yield the required logic function. Carry look-ahead adder is a major functional block in arithmetic logic unit due to its high ...
