Cadence Design Systems Interview Questions, Process, and Tips

Q1. Difference between sanity and smoke
Ans. 
Sanity testing is a narrow and deep testing approach to check if the specific functionality is working fine after changes, while smoke testing is a broad and shallow testing approach to check if the software build is stable enough for further testing.
• Sanity testing focuses on specific functionality, smoke testing checks overall stability

• Sanity testing is usually performed after a specific change, smoke testing is perfo...read more

Q2. Difference between regression n retesting
Ans. 
Regression testing is testing the entire application after changes, while retesting is testing specific areas after fixes.
• Regression testing is done to ensure that new code changes do not affect existing functionality.

• Retesting is done to verify that a specific bug or issue has been fixed.

• Regression testing involves running the entire test suite, while retesting focuses on specific test cases.

• Example: After fixing a bu...read more

Q1. Explain the MOSFET operation and Body Bias effect
Ans. 
MOSFET is a type of transistor used in electronic devices. Body Bias effect refers to the change in threshold voltage due to biasing of the body terminal.
• MOSFET stands for Metal-Oxide-Semiconductor Field-Effect Transistor.

• It has three terminals: Gate, Source, and Drain.

• The operation of a MOSFET involves controlling the flow of current between the Source and Drain terminals by applying a voltage to the Gate terminal.

• Bod...read more
