# EDA Stage Checkpoint Golden Use this skill to freeze reusable checkpoints and avoid rerunning all stages. ## Step 1: Build a checkpoint bundle ```bash ROOT=/mnt/research/Hu_Jiang/Students/Fang_Donghao/TAMU-ASAP07-BSPDN-BPR-V0.00 cd "$ROOT" bash scripts/debug/create_stage_golden_checkpoint.sh \ --design=<design> \ --tag=<golden_tag> \ --tech-profile=<tech_profile> \ --place-run-dir=<run_dir_for_placed_def> \ --cts-run-dir=<run_dir_for_postcts_def> \ --route-run-dir=<run_dir_for_routed_def> ``` Output root: - `regression/stage_checkpoints/<tag>/<design>/` ## Step 2: Verify integrity Check: - `manifest.tsv` - `sha256.tsv` - `restore_examples.sh` Do not edit files in an existing tag after creation. ## Step 3: Maintain stable pointer Update a stable symlink when a new golden is approved: ```bash ln -sfn <tag> regression/stage_checkpoints/<design>_stagegolden_current ``` ## Step 4: Resume from chosen stage Use generated restore templates in: - `regression/stage_checkpoints/<tag>/<design>/restore_examples.sh` Load `references/tagging_policy.md` for tag naming and source policy.
