This document summarizes the implementation of a multiplexer and demultiplexer on Cadence software. It discusses the theory behind multiplexers and demultiplexers, provides their truth tables, and describes creating the main and testbench modules using dataflow and gate level models. Screenshots and waveforms are shown to verify the multiplexer and demultiplexer designs. The student learned how to implement these logic circuits in Cadence through this experiment.

1. AIM : To implement multiplexer and demultiplexer on CADENCE software
Tools Used : Cadence NC-SIM
Theory : Multiplexers are used as one method of reducing the number of logic gates required in a
circuit or when a single data line is required to carry two or more different digital signals.A
demultiplexer performs the reverse operation of a multiplexer i.e. it receives one input and
distributes it over several outputs
Truth Tables: Multiplexer
Demultiplexer

2. Main module:
Using Dataflow model:
Using gate level:

3. Testbenchmodule: Dataflow:
gaga
Gatelevel:

4. Snapshot of total screen:

5. Waveforms :
Multiplexer waveforms:
a=0; b=0;
a=0; b=1;
a=1; b=0;
a=1; b=1;

6. Demultiplexer waveforms:
a=1;b=0;
Learning outcomes: From this experiment I have learnt how to implement the Multiplexer and
demultiplexer in cadence software
