DFT Interview Prep

Section goal

Whiteboard-ready DFT reasoning: scan architecture, coverage debates, silicon mismatch triage, and senior Q&A.

How to study this section

1. Start with the topic hub for architecture and ownership context.

2. Use mechanism and reports pages to map assumptions to metrics.

3. Use debug and worked examples for real closure patterns.

4. Finish with checklist and silicon impact before release decisions.

INTERVIEW ANSWER LOOP

state metric -> explain mechanism -> request evidence -> propose fix -> list regression

Metric graph

ANSWER QUALITY

mechanism clarity + ownership clarity + regression discipline

Reports and artifacts

• whiteboard rubric

• scenario scorecard

• trap checklist

• follow-up depth index

Mini case study

Candidate improved from tool-only answers to mechanism-first narratives by using metric->artifact->decision template.

Debug branches

• Always state assumptions

• Name cross-team owners

• Discuss risk and fallback plan

Senior review question

Ask: what evidence proves this DFT decision is safe for production?
