Project Title: Multiplexer Based design of Half Adder
The circuit was designed and simulated in eSim Software
Procedure:
1)The circuit was built using eSim Nmos and Pmos transistors
2)The netlist is generated if this circuit
3)The eSim Nmos and Pmos are replaced with skywater technology
4)The .cir file is simulated in ngspice
5)The waveforms are observed.

Difficulties faced:
1)Due to threshold voltage of the transistors,the output obtained is not accurate
Example: expected output 5v , waveform output is 4.2v
2)For simulation, Ngspice took long time to respond
