DRCBench

DRCBench is a benchmark suite for evaluating layout pattern generation and verification under advanced semiconductor design rules. Built on the ASAP7 (7 nm FinFET) PDK, it offers diverse, realistic metal-layer patterns to bridge the gap between academic layout generation and industrial DRC verification. The primary intended usage is to evaluate the ability of existing ML algorithms to produce design-rule-compliant layouts and to measure corresponding diversity scores.

Repository layout

• asap7/ – Git submodule mirroring the ASAP7 PDK. Consult asap7/README.md for installation notes, DRM, and Calibre deck guidance.
• M1_data/ – Metal-1 benchmark set derived from the ASAP7 7.5-track standard-cell library:
  • gds/ – 212 single-layer GDS extracts (*_ASAP7_75t_R_M1.gds) ready for import into KLayout, Calibre, or other DRC engines.
  • png/ – Raster previews for quick visual inspection (*_ASAP7_75t_R_M1.png) plus a single INVx1_test.png example used during dataset validation.

Getting started

1. Clone the repository with submodules to pull the ASAP7 collateral:

   git clone --recurse-submodules https://github.com/glzhou97/DRCBench.git
   # or, if already cloned:
   git submodule update --init --recursive

2. Follow the instructions in asap7/asap7_pdk_r1p7/README_ASAP7PDK_INSTALL_201210a.txt to install the PDK and, if needed, download the proprietary Calibre decks from the ASAP7 distribution site.
3. Point your DRC or layout-viewing tool to the appropriate tech files (e.g., the KLayout .lyp and .lyt configs or Calibre rule decks) when loading patterns from M1_data/gds.

Working with the Metal-1 dataset

• Coverage Currently, this dataset only contain patterns that can cover M1.S.4/6 rule and related area and width rules. PNG files are provided for model training. Expansion to additional rule categories is ongoing.
• Inspection: Open any pattern GDS in KLayout, Virtuoso, or an equivalent tool to visualize the metal geometries. The PNG thumbnails provide at-a-glance previews to help triage interesting cases before loading the full layout.
• Rule checking: Use the official ASAP7 Calibre decks (recommended), or translate the rules into your in-house checker, to benchmark false positives/negatives and runtime on the provided patterns.
