Execute delay-model validation gates against HPWL baselines. Use when evaluating model consistency, running Gate-0 contract checks, building Gate-1 bucketed scorecards, performing wirelength-aware correlation checks, or deciding readiness for active optimization.

- Execute delay-model validation gates against HPWL baselines. Use when evaluating model consistency, running Gate-0 contract checks, building Gate-1 bucketed scorecards, performing wirelength-aware correlation checks, or deciding readiness for active optimization.
Delay Model Gate Evaluator
Run these checks before promoting model changes into placement/CTS optimization.
Placeholder conventions
<merged_or_unified_tsv>: Path to a merged or unified TSV file, for exampledata/merged_asap7_delay_v2.tsvordata/unified_timing_run03.tsv.<tag>: Descriptive run identifier such asrun03_lr1e-3orv2_bspdn_baseline. Use one naming scheme consistently across gates.
Gate-0: Contract and sign consistency
ROOT=/mnt/research/Hu_Jiang/Students/Fang_Donghao/TAMU-ASAP07-BSPDN-BPR-V0.00
cd "$ROOT"
python3 scripts/debug/check_delay_model_contract.py \
--input-tsv <merged_or_unified_tsv> \
--delta-sign back_minus_front \
--min-sign-acc 0.60 \
--out-prefix slurm_logs/04_delay_modeling/<tag>.contract
Use --strict for CI-style hard fail.
If Gate-0 fails: Check the contract output first. If sign accuracy is below the threshold, inspect the worst-performing net groups for data quality issues such as missing features, outlier wirelengths, or inconsistent labels. Re-train or filter the input TSV before proceeding.
Gate-1: Bucketed scorecard
python3 scripts/debug/bucketed_delay_model_scorecard.py \
--input-tsv <merged_or_unified_tsv> \
--delta-sign back_minus_front \
--out-prefix slurm_logs/04_delay_modeling/<tag>.bucketed
Promotion criteria
- Gate-0 sign contract passes (sign accuracy >= 0.60; use >= 0.75 for production-critical flows).
- Key buckets (long + high fanout) show correlation equal to or better than the HPWL baseline.
- Scorecard results are archived with clear run tag and data source.
If promotion criteria are not met: Do not proceed to active optimization. Iterate on the delay model instead by reviewing feature engineering, checking training-data coverage for underperforming buckets, and re-running both gates after the update.
