SQuADDS Layouts

Versioned GDS layout artifacts for the SQuADDS simulation database.

This release contains 4,577 layouts across two SQuADDS coupler datasets:

• 3,683 GeneralizedCapNInterdigital layouts matched to coupler-GeneralizedCapNInterdigital-cap_matrix simulation rows.
• 894 reproducibly generated CapNInterdigitalTee layouts, one for every row in coupler-CapNInterdigitalTee-cap_matrix.

Each layout is recorded in metadata/manifest.parquet with a stable layout ID, an exact-file SHA-256 checksum, its originating simulation source_id, and geometry metadata extracted in micrometers.

Access

Use the layout-manifest configuration to query metadata, then download one raw GDS file by its gds_path. The SQuADDS Python LayoutClient verifies the checksum before returning the local cache path.

The raw files are organized under:

raw/GeneralizedCapNInterdigital/<campaign>/<instance>.gds
raw/CapNInterdigitalTee/generated_from_cap_matrix/<instance>.gds

Layer Semantics

The current generalized capacitor layout convention is documented in metadata/layer-semantics-v1.json. The GDS files retain their original simulation-domain geometry, ports, and layer/datatype pairs.

Provenance

The paired generalized capacitor simulation data was contributed by Saikat Das of the Levenson-Falk Lab at USC. This repository excludes seven local GDS files that did not have matching simulation rows.

The CapNInterdigitalTee layouts are deterministic GDS exports produced from the corresponding SQuADDS_DB design options using Qiskit Metal.
