Design Verification Engineer – Interview Questions & Answers
Q1. Can you explain what Design Verification (DV) is and why it is important?
A1. Design Verification is the process of checking whether a hardware design (such as an ASIC or SoC) works as intended before manufacturing. It helps to catch functional errors early, ensures design quality, reduces the cost of fixing bugs later, and avoids failures in silicon. Without DV, even small mistakes can cause major product failures.
Q2. What is constrained-random verification, and why is it used?
A2. Constrained-random verification is a method where random test inputs are generated within certain rules (constraints) to check all possible scenarios. It is useful because it can test corner cases that are hard to think of manually, which improves coverage and increases the chances of finding hidden bugs.
Q3. What are functional coverage and code coverage in DV?
A3.
- Functional coverage checks if all planned scenarios (like protocol rules, features, and corner cases) have been tested.
- Code coverage checks how much of the design code (RTL) was executed during tests (e.g., statements, branches).
Both are important to measure completeness of verification.
Q4. How do you debug a failure during verification?
A4. First, I check the failure log and waveform using tools like Verdi or SimVision. Then, I trace back to see if the failure is in the testbench or the RTL design. I collaborate with the design team if it is a design bug, or I fix my testbench if it’s a verification issue. Systematic debugging saves time and ensures correctness.
Q5. What scripting languages or tools have you used in verification?
A5. I have used scripting languages like Python, TCL, Perl, and Shell to automate tasks, manage test cases, run simulations, and process logs. These scripts help save time and reduce manual errors in verification flows.
Q6. What is UVM, and why is it widely used in verification?
A6. UVM (Universal Verification Methodology) is a standardized framework built on SystemVerilog for creating reusable and scalable testbenches. It provides ready-to-use components like drivers, monitors, and scoreboards, which help to verify complex designs efficiently.
Q7. What is your understanding of protocols like AXI, APB, or I2C?
A7. These are standard communication protocols used inside SoCs:
- AXI (Advanced eXtensible Interface): High-performance, widely used for CPU-to-memory communication.
- APB (Advanced Peripheral Bus): Simple protocol used for low-bandwidth peripherals.
- I2C/SPI: Used for external device communication like sensors or memory chips.
Understanding these protocols is important for verifying IP blocks that use them.
Q8. How is Design Verification different for CPU and GPU environments?
A8. In CPU/GPU environments, verification involves complex instruction sets, pipelines, cache systems, and parallel execution. The challenge is ensuring correctness across many scenarios, like interrupts, multi-threading, and memory consistency. Verification requires detailed architectural knowledge compared to smaller peripheral IPs.
Q9. What is an ECO (Engineering Change Order) and how does it affect verification?
A9. An ECO is a design change made after initial verification. When an ECO happens, we need to re-verify the updated parts of the design and ensure that the change didn’t break anything else. Regression testing is very important in ECO verification.
Q10. Why do you want to work as a Design Verification Engineer at Meta?
A10. Meta is working on cutting-edge ASICs and SoCs that power AI/ML and data center workloads. I am passionate about verification because it ensures the quality and success of such critical hardware. Working at Meta will allow me to learn from experts, contribute to innovative designs, and grow my skills in high-performance hardware verification.
