ASIC design interviews are usually flow-oriented: interviewers want to see that you understand how a design moves from RTL through synthesis, DFT insertion, physical design, and sign-off — and why decisions made early affect what's possible later.

This bank covers each stage of that flow, plus the power, yield, and ASIC-vs-FPGA questions that come up when interviewers probe your judgment, not just your recall.

ASIC Design interview questions by subtopic

ASIC Design Flow

The end-to-end path from specification to tapeout.

Walk through the complete ASIC design flow from RTL to tapeout.
What deliverables are typically handed off at each stage of an ASIC project?

RTL to Gate-Level Synthesis

How RTL becomes a technology-mapped netlist.

What's the difference between a technology-independent and technology-mapped netlist?
How does synthesis handle timing constraints defined in an SDC file?

Design for Test in ASIC

Building testability into the design itself.

Why is DFT insertion typically done before physical design, not after?
What is fault coverage, and what's considered an acceptable target in industry?

Physical Design & Sign-off

The final checks before a design is fabrication-ready.

What sign-off checks does a design need to pass before tapeout?
What is IR drop, and why is it a physical design concern?

Power & Performance Trade-offs

Balancing speed, area, and power in real designs.

What is dynamic vs. static power, and how do you reduce each?
Explain clock gating and its impact on power.

Yield & Manufacturing

How design decisions affect real-world silicon yield.

What factors affect silicon yield, and how does design account for them?
What is DFM (Design for Manufacturability)?

Verification for ASIC

Why verification often dominates ASIC project timelines.

Why is verification effort typically larger than design effort in modern ASICs?
What's the role of a testbench scoreboard in a UVM environment?

ASIC vs FPGA

Understanding when each implementation choice makes sense.

When would you choose ASIC over FPGA for a product, and vice versa?
How does NRE (non-recurring engineering) cost factor into that decision?
