# SQuADDS Layouts
Versioned GDS layout artifacts for the [SQuADDS simulation database](https://huggingface.co/datasets/SQuADDS/SQuADDS_DB).
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:
```text
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.
