Nvidia Dft Design Engineer Interview Questions and Answers

Digital design problems involve challenges in designing and implementing digital circuits and systems.

• Understanding and optimizing power consumption

• Ensuring signal integrity and minimizing noise

• Implementing efficient clocking strategies

• Addressing timing issues and meeting performance requirements

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.
