Detection of both SA0 and SA1 faults on a VLSI circuit for 4-bit EVEN parity checker circuit

Procedure

These procedure steps will be followed on the simulator:

Step 1. The inputs x, y, z and P are provided with switches, initially in OFF position.

Step 2. The values of inputs x, y, z and P can be alternated between ON and OFF positions by clicking on the image of the switch.

Step 3. Initially, all lines are set to "No fault" . To set a stuck-at fault on any line, press the respective button. The value at the respective lines alternates between , and .

Step 4. Click on the "Run" button. The output will be displayed in the table given, along with the corresponding ideal output (displayed in red when there are faults, otherwise in green).
