Chip-level RDC Reviews

The review meeting: inputs, questions, and outputs.

On this page

    The chip-level RDC review is where all the evidence meets judgement. It is a meeting with fixed inputs, fixed questions, and recorded outputs, not a status update. Its verdict per reset domain is one of three: closed, open with named actions, or waived with recorded evidence.

    Inputs: what must be on the table

    Input

    Without it the review cannot

    Frozen reset intent with revision

    Judge any finding, because every verdict hangs off the intent.

    Structural reports on the final RTL

    Confirm zero open defects rather than trusting a summary count.

    Finding dispositions and waiver records

    Check that each finding has exactly one owner and one fate.

    Dynamic-check results and coverage holes

    Confirm behaviour, not just structure, and see what never ran.

    Change delta since the last review

    Spot RTL, intent, or IP changes that silently void earlier verdicts.

    Questions: what the review asks

    For each reset domain: is the intent complete and reviewed, are all findings dispositioned, do the dynamic checks cover the required sequences, are waivers approved and unexpired, and has everything changed since the last clean run been re-checked? For the chip: do inter-block assumptions hold at every connection, is third-party IP contracted on every checklist row, and do warm and power-transition sequences have their own evidence? Any no becomes a named action with an owner and a date.

    Outputs: what the review records

    Per domain the verdict with its evidence pointers, the action list with owners and dates, newly approved or renewed waivers with expiry, and the delta statement: which changes since the last review were re-checked and how. The minutes are signoff evidence themselves, so they name revisions and runs, never just conclusions.

    Common pitfall

    Reviewing a slide summary instead of the reports lets reclassified findings and stale runs through. The review reads the finding list and the run revisions directly; summaries brief the meeting but never replace the evidence.

    Interview

    Expect: how do you run an RDC review? Answer: fixed inputs including frozen intent and final-RTL reports, per-domain questions ending in named actions, and recorded outputs with evidence pointers, and insist on reading reports rather than summaries.

    Check yourself A domain shows zero open defects but its dynamic checks ran on the previous RTL revision. What is the verdict?

    Open with a named action: re-run the dynamic checks on the final RTL. Structure and behaviour must both be proven on the same revision.

    Check yourself Why must review minutes name revisions and runs instead of just conclusions?

    Because the minutes are signoff evidence. A conclusion without its evidence pointer cannot be audited later, for example to check whether a late change voided it.
