VLSI DV Interview Puzzles

A practice bank of real VLSI Design Verification interview puzzles: SystemVerilog language traps, OOP/testbench gotchas, concurrency and timing races, randomization and constraints, SVA assertions, functional coverage, logic/aptitude brain teasers, and live debug scenarios โ€” each with code, a hint, a worked solution, the exact answer, and the gotcha.

What this course is

This is a puzzle bank, not a lecture series. Every page is a real interview-style puzzle. You get the prompt and code first; predict the answer, then check the worked solution, the exact answer, and the specific trap interviewers are testing.

  • 192 worked puzzles across 8 themes (24 per theme, 6 per topic).

  • Each puzzle: prompt, code, hint, step-by-step solution, exact answer, gotcha, and a follow-up question.

  • Difficulty tags (Easy / Medium / Hard) so you can ramp up the way interviewers escalate.

  • Section Q&A and interview-round walkthroughs to rehearse explaining your reasoning out loud.
