Synthesis Whiteboard Framework: Step-by-Step Walkthrough

Step-by-step analysis walkthrough

Use when you own Synthesis Whiteboard Framework in a synthesis closure review.

1. Confirm exact run context (RTL/SDC/lib/switch set).

2. Open section QoR dashboard and identify first drift.

3. Inspect topic-level report for mechanism evidence.

4. Determine owner and candidate reversible action.

5. Apply one change only; avoid bundled fixes.

6. Run full timing/area/power checks.

7. Validate side effects on neighboring path groups.

8. Publish memo with outcome and residual risk.

Artifacts to collect

• whiteboard template, answer rubric, mock interview log

• QoR dashboard

• run manifest

• constraint diff

• regression matrix

Reports and artifacts

• mock scorecard

• scenario debrief

• Q&A coverage

• framework adherence

Mini case study

Candidate improved by replacing tool-command answers with evidence-driven closure narratives.

Debug branches

• State assumptions first

• Defend option tradeoffs

• Close with rollback/regression

Senior review question

Ask: what evidence proves this QoR move is real and stable?

Key takeaways

• State exact run context (RTL, SDC, libs, switches) with every QoR claim.

• Re-run timing, area, and power regressions after each synthesis ECO.

Common pitfalls

• Comparing runs with mismatched constraints or library views.

• Timing-only fixes that violate power or area budgets.

• Skipping equivalence checks after structural changes.

Principal synthesis review addendum

Strong synthesis answers narrate constraint intent, mapping path, QoR evidence, and regression risk in a fixed reusable structure.

Metric: answer completeness score, mechanism-first explanation quality
