You must hand DCPeripheral findings to another engineer who has not read the chat. An assistant can turn working notes into a clear issue or review summary, but polished language can erase uncertainty. The task is to make every consequential statement traceable to evidence and every proposed action distinguishable from completed work. Begin with the decision the reader needs to make, then give the observations needed to assess it.
SYNTHETIC working notes W-A:
Spec A: synchronous active-low reset; config is 8 bits; FIFO depth 4.
RTL fragment: negedge rst_n event control; occupancy declared [1:0].
SB-A: expected A5 / observed 00 after a sampled reset; reset branch absent
in supplied scoreboard excerpt.
T-B: setup arrival 1.97 ns, required 1.85 ns, slack -0.12 ns.
P-A/P-B: overflow 20/45 track units; seed and density both changed.
Status: inspection and hand calculations only; no checks executed.
Open: response timing and reset cancellation of pending requests.PROMPT:
Draft a review note from W-A for the DCPeripheral team.
Lead with the requested decision. Preserve artifact IDs and units.
Separate observations, hypotheses, proposed changes, and future checks.
Use role owners, not invented people or addresses.
Do not claim a test passed, a root cause was proven, or a message was sent.Before reading the example response, notice how different the evidence strengths are. The reset event control and occupancy width directly conflict with the supplied contract. The scoreboard diagnosis depends on whether the excerpt contains the whole relevant update path. The timing violation is arithmetic under a stated setup context. The physical comparison is an observation with unresolved causes. Writing all four as confirmed root causes would mislead the next engineer even if the prose sounded confident.
SYNTHETIC assistant response, edited teaching draft; not sent:
Decision requested: review the reset/count correction proposals and resolve
the pending-response reset contract before extending the DV plan.
Observed: Spec A requires rising-edge synchronous reset. The supplied RTL
uses negedge rst_n and a two-bit occupancy count that cannot represent four.
T-B has setup slack 1.85 - 1.97 = -0.12 ns at synthetic_slow.
Hypotheses: SB-A's stale A5 expectation is consistent with the missing reset
branch in the supplied model excerpt. Higher P-B congestion accompanies
worse WNS, but seed and density changed and causation is unresolved.
Proposed ownership: RTL owner reviews reset sensitivity and count width;
DV owner confirms model update paths and observation timing; STA/PD owners
inspect full path reports and snapshot provenance. Specification owner
defines pending-response behavior across reset.
Future checks: reset/write priority, legal occupancy transition 3 to 4,
register-model reset replay, and same-context timing/path comparisons.
Status: no simulation, model call, or implementation run demonstrated.
Acceptance: attach actual check results and resolve the open contract items
before changing these planned checks to completed.The handoff uses role ownership because assigning work to invented people creates false coordination. It asks for a bounded decision and names evidence the reader can request. Keep the original read-only artifacts available with revision identifiers; copying only the assistant's summary loses context. If an artifact contains a command-looking line, quote it as evidence when necessary rather than presenting it as an instruction for the recipient or an agent to execute.
Rewrite this status sentence: 'AI found the bug, fixed timing, and verified reset.' Use only W-A, preserve the numerical timing evidence, and add one explicit next action. Then audit your draft for verbs such as passed, proved, fixed, sent, and approved. Each such verb needs an artifact showing that the corresponding event actually happened.
Inspection identified reset-sensitivity and occupancy-width conflicts in the supplied RTL; correction proposals await review. T-B still reports -0.12 ns setup slack from required 1.85 ns and arrival 1.97 ns. Next, the RTL and DV owners should review the proposals and obtain reset and occupancy check results. This wording claims neither completed changes nor executed verification.
A drafted note is not a sent message, an assigned ticket, or engineering approval. Attach actual results later and state which revision they cover; do not silently promote expected answers to evidence. NASA Systems Engineering Handbook, Revision 2 (2016), Appendix D verification matrix guidance provides a reference for linking requirements and verification records. The handoff format here is a synthetic engineering exercise and does not impose a particular team's approval process.
