Q3. No. of patterns to detect fault on XOR gate

Ans.

There are 3 patterns to detect faults on an XOR gate.

There are 3 possible fault patterns on an XOR gate: Stuck-At-0, Stuck-At-1, and Inversion.
Stuck-At-0 fault pattern occurs when one input is always 0, regardless of the other input.
Stuck-At-1 fault pattern occurs when one input is always 1, regardless of the other input.
Inversion fault pattern occurs when the output is inverted compared to the correct XOR gate output.

Q3. How compression ratio can be tweaked, what are the factors ( how coverage, Patten count gets impacted).

Ans.

Compression ratio can be tweaked by adjusting the volume of the combustion chamber. This affects fuel efficiency and power output.

Compression ratio is the ratio of the volume of the combustion chamber at its largest to its smallest.
Increasing compression ratio can improve fuel efficiency and power output, but too high a ratio can cause engine knocking.
Factors that impact compression ratio include the size and shape of ...

Q4. How have I observed hold violations and setup violations in my design. What I did after that, etc

Ans.

I have observed hold and setup violations in my design and took necessary actions.

I used static timing analysis (STA) to identify hold and setup violations.
I fixed hold violations by adding delay cells or increasing clock period.
I fixed setup violations by reducing delay or decreasing clock period.
I also checked for false paths and multi-cycle paths.
I re-ran STA after fixing violations to ensure timing closure.
I docume...
