Retry timed-out Track B equivalence checks with a longer budget

Perform a longer-budget sequential-equivalence retry for the Track B multiplier-heavy timing-closure candidates whose current equivalence checks time out, and determine whether any of those candidates satisfy their timing targets.

Background

Four Track B candidate-task pairs received equivalence-checker timeouts rather than definitive pass or fail outcomes. Because the pipeline stops before synthesis and static timing when equivalence checking fails or times out, the paper cannot determine whether any of those candidates would have met the physical timing target.

The authors identify the current 60-second budget as potentially inadequate for multiplier-heavy datapaths and specify a longer-budget retry as the needed follow-up.

References

Correcting this requires a longer-budget sec retry, a single overnight run, which we have not performed; the same timeout-vs-verdict distinction discussed for the external audit (Section~\ref{sec:audit-method}) applies equally here, and we do not currently retry a timed-out sec run the way the mutation engine retries a timed-out simulation.
