Senior Verification Engineer Interview Questions and Answers

Functional coverage is a metric used to measure how much of the design functionality has been exercised by the verification environment.

• Functional coverage is used to ensure that all the features of the design have been tested.

• It is a measure of how much of the design functionality has been exercised by the verification environment.

• Functional coverage is typically defined in terms of coverage points, which are specific aspects of the design that need to be tested.

• Coverage poi...read more

Randomisation is a technique used in verification to generate random test cases.

• Randomisation is used to increase the probability of finding bugs in a design.

• It involves generating random inputs to test the functionality of a design.

• Randomisation can be used in both simulation and formal verification.

• It helps in identifying corner cases and edge cases that may not be covered by directed tests.

• Randomisation can be controlled using constraints to ensure that the generated input...read more

A FIFO checker is a verification component used to monitor and validate the behavior of a First-In-First-Out buffer in a design.

• Implement a monitor that tracks the input and output operations of the FIFO buffer

• Check that the data is read out in the same order it was written in

• Verify that the FIFO buffer does not overflow or underflow

• Use assertions to flag any violations of FIFO behavior

• Example: Monitor the write and read pointers of the FIFO buffer and compare them to ensure ...read more
