Simulation
			
			
				- The circuit simulated is as shown in the below image.
 
				- Click the input switches
 to select the required inputs named "x", "y", "z" and "w". 
				-  The simulation will display corresponding output. Output is displayed as a glowing bulb
 
				- Press the "RUN" button to display the output in the truth table.
 
				- "reset" button clears all entries of truth table.
 
				- At specific positions, small switches
 make the lines stuck-at-0. Clicking them simulates SA0 faults at the said locations. 
				- Repeat above steps for all possible inputs and verify the truth table
