CircuitGen Private Artifacts Index

This repository contains the private CGDSL data plus the published artifacts for the netlist_to_layout_v1 v1 experiment lineage.

Latest repaired CGDSL overlay

For future preprocessing, training, and eval, prefer:

• derived/cgdsl/20260307-081439-fix-open-netlistify-ams-overlay

This overlay copies forward the unchanged roots from:

• derived/cgdsl/20260305-134840-fix-build-cgdsl-patched

and regenerates only these three roots after the 2026-03-07 repair pass:

• open-schematics_hf
• netlistify_schematic_images_hf
• ams-net.github.io

Historical note:

• the published netlist_to_layout_v1 12k-step run below still used derived/cgdsl/20260305-134840-fix-build-cgdsl-patched
• the exact historical inputs for that run remain listed later in this README

Notes

• The restart snapshot is the source of truth for reproduction/restart.
• The experiment package is the source of truth for analysis/reporting.
• The exact source JSONL versions used here are committed in this repo and fingerprinted here so the cache/checkpoint lineage is not dependent on this machine alone.

Historical note on max_steps

This published run lineage did not use a constant max_steps=12000 for the entire training run. Training began with max_steps=100000, following the original v1 plan. Near step ~11000, the run configuration was changed to max_steps=12000, and training then stopped at step 12000.

Interpretation guidance:

• the final artifact state and some copied config files may show max_steps=12000
• that value reflects the late-run edited state, not the schedule used for most of training
• most of the run therefore occurred under the earlier 100000-step configuration
