-It's a digital alu_xor having two copies of ALUs, namely: alu1 and alu2. The outputs generated by both the ALUs are XORed to yield any discrepancies between the designs. Any difference in the result turns out to be conditions relating to faults.
+It's a digital alu_xor having two copies of ALUs, namely: alu1 and alu2 that perfoms basic arithmetic operations addition, and subtraction, and logical operations AND and OR. The outputs generated by both the ALUs are XORed to yield any discrepancies between the designs. Any difference in the result turns out to be conditions relating to faults.
**Tests to be carried out: (Post fabrication)**
1) To inject various faults and study the characteristics.
