Tapeout Readiness Review

The review meeting, evidence per owner, go and no-go criteria, and the surprises of the last week.

  • 3topics
  • 3lessons

The readiness review is where the chip asks permission to leave. Every owner brings evidence, the integrator brings the manifest, the dashboard and the waiver table, and the room decides go or no-go by rules written before anyone entered. Run well, it takes an hour and confirms what the scripts already said. Run badly, it relitigates three months of waivers from slides. This topic scripts the good version on NanoSoC: who brings what, what the decision rule is, and which last-week failures to expect. Its one job is the meeting and its decision; what a late change costs after a go is the next topic.

Lesson

After it you can...

Evidence per Owner

State what each owner must bring, and refuse substitutes.

Go and No-Go

Score the decision by rule, with four live waivers and one new request.

Last-Week Surprises

Name the failures that strike in the final week and their guards.

Suggested order: top to bottom. Evidence first, because the decision rule only works on real inputs; then the rule; then the surprises that test both. The verification sign-off board this mirrors is The Sign-Off Board, and the review to attend first is The Tape-Out Review.

Check yourself An owner brings slides summarising results instead of the results. Admit or refuse?

Refuse: summaries are claims, and the review audits evidence. The manifest row, the dated result on the frozen baseline, or the meeting waits.

The whiteboard go and no-go drill with several open waivers is scored on classification, evidence and the decision rule. The second lesson is that drill with the NanoSoC table.
