This section turns the rest of the course into interview performance. CDC and RDC interviews test judgement under uncertainty: can you name the crossing, say how it fails, pick a containment, and say what evidence would close it? Every lesson here uses the same answer framework, Assumption, Mechanism, Trade-off, Evidence, so the habit transfers to any question you have not seen before.
Design and verification engineers preparing for digital-design, DFT-adjacent, or signoff interviews at any level, and interviewers looking for calibrated questions with a scoring rubric. Junior candidates should lean on the framework and drills topics; senior candidates should be able to narrate the scenarios and survive the expanded bank, including the design-review questions.
Work it in this order. First the whiteboard framework: one answering habit for every question. Then the drills to make the habit fast. Then the scenarios, which rehearse narration of messy, realistic debug stories. Finally the Q&A bank and the expanded bank for breadth. Time yourself on the drills and the rapid-fire round; everything else rewards slow, mechanism-first answers.
Topic | Lessons | After it you can... |
|---|---|---|
4 | Answer any crossing question with Assumption, Mechanism, Trade-off, Evidence, draw the crossing, name the failure mode, and score yourself with the rubric. | |
3 | Apply the framework under time pressure to single-bit, multi-bit and FIFO, and reset crossings. | |
4 | Walk through a metastability bug from symptom to fix as a clean narrative. | |
3 | Reason about a rare escape that simulation missed, and say what evidence exists and what process changes follow. | |
3 | Diagnose a FIFO pointer mismatch and name the guards that prevent it. | |
3 | Argue both sides of a CDC waiver and land on a defensible outcome. | |
3 | Handle reset-crossing waivers under schedule pressure and communicate the risk honestly. | |
5 | Answer core questions on fundamentals, protocols, reconvergence, resets and signoff at a strong level. | |
2 | Survive senior design-review questions and a 20-question rapid-fire round. |
Frameworks first, then drills, then scenarios, then the bank: the answering habit first, speed second, narration third, breadth last.
