CDC Review Gate

The gates, checklists, readiness definition, and handoff that close CDC signoff before tape-out.

  • 4topics
  • 4lessons

Signoff closes in gates, not in a single heroic week. Each gate has entry and exit criteria, each owner has a checklist, readiness has a definition everyone shares, and the implementation and test teams receive a handoff they can actually use. This topic turns “we are clean” from a feeling into a checkable claim.

Lesson

After it you can...

Pre-Tapeout Gates

Name the gates through a project and their entry and exit criteria.

Review Checklists

Apply the design, verification, and signoff checklists.

Signoff Readiness

Judge whether “closed” is true: findings, waivers, constraints, dynamic checks.

Handoff to Physical Design and DFT

List what implementation and test teams need about crossings and constraints.

Check yourself Why gates instead of one final review?

Because each gate catches its class of problem while fixing is still cheap, and the exit criteria of one gate are the entry criteria of the next — a single final review compresses all of that into the moment of maximum schedule pressure.
