Marvell Semiconductors Interview Questions and Answers

Q1. Difference between bias and variance
Ans. 
Bias is error due to overly simplistic assumptions, variance is error due to overly complex models.
• Bias is error introduced by approximating a real-world problem, leading to underfitting.

• Variance is error introduced by modeling the noise in the training data, leading to overfitting.

• High bias and low variance models are simple and may not capture the underlying patterns in the data.

• High variance and low bias models are ...read more

Q1. How will I write Verilog Code to exchange the data of two FF Without Using Temp FF? Now Check the hold and Setup Violation.
Ans. 
To exchange data of two FF without using temp FF in Verilog and check hold and setup violation.
• Use a temporary variable to store the data of one FF before exchanging it with the other FF.

• Ensure proper timing constraints are met to avoid hold and setup violations.

• Check the timing analysis report to verify if there are any violations.

• Consider using synchronous or asynchronous reset signals to properly handle the data exc
