RTL Design and Verification Engineer Interview Questions and Answers

Updated 30 Dec 2024

Q1. Write d ff with test bench and verify it.

Ans.

Design and verify a D flip-flop with test bench

Design a D flip-flop using Verilog or VHDL
Write a test bench to apply inputs and verify outputs
Simulate the design using a simulator like ModelSim
Check for correct functionality and timing constraints

Q2. Designing of a frequency divider .

Ans.

A frequency divider is a digital circuit that takes an input signal and produces an output signal with a frequency that is a fraction of the input frequency.

Frequency dividers are commonly used in digital systems to generate clock signals at lower frequencies.
They can be implemented using flip-flops, counters, or other digital logic elements.
For example, a divide-by-2 frequency divider will output a signal with half the frequency of the input signal.
Frequency dividers are ess...read more

Q3. Difference between task and function

Ans.

Task is used for sequential execution while function is used for parallel execution.

Task is used for modeling sequential behavior in Verilog/SystemVerilog
Function is used for modeling combinational logic in Verilog/SystemVerilog
Task can contain delays and blocking statements
Function cannot contain delays or blocking statements

Q4. Designing of a edge detector

Ans.

An edge detector is a circuit that detects transitions from one logic level to another in a digital signal.

Utilizes flip-flops to store previous signal values
Compares current signal value with previous value to detect edges
Can be implemented using Verilog or VHDL
Commonly used in digital signal processing applications
