Fabrication API

Coming with MetoFab

The fabrication API will launch alongside the MetoFab platform. This page outlines the planned interface.

Overview

The fabrication API connects MetoSim simulation results to nanofabrication workflows. It handles GDS export, design rule checking, and process recipe generation.

Planned Endpoints

Method	Endpoint	Description
POST	/v1/fabrication/export-gds	Export simulation geometry to GDS II
POST	/v1/fabrication/drc	Run design rule check
POST	/v1/fabrication/recipe	Generate fabrication process recipe
GET	/v1/fabrication/pdks	List available process design kits

GDS Export (Planned)

Convert a MetoSim simulation geometry directly to GDS II format:

// POST /v1/fabrication/export-gds
{
  "job_id": "a1b2c3d4-...",
  "layer_mapping": {
    "Si": {"layer": 1, "datatype": 0},
    "SiO2": {"layer": 2, "datatype": 0}
  },
  "grid_resolution_nm": 1
}

Response:

{
  "gds_url": "https://storage.metosim.io/gds/design.gds",
  "layers": [1, 2],
  "bounding_box_um": [4.0, 4.0],
  "polygon_count": 1247
}

Design Rule Check (Planned)

Validate a design against foundry-specific rules before submission:

// POST /v1/fabrication/drc
{
  "gds_url": "https://storage.metosim.io/gds/design.gds",
  "pdk": "generic_soi_220nm",
  "rules": {
    "min_feature_nm": 100,
    "min_spacing_nm": 80,
    "min_radius_nm": 50
  }
}

Response:

{
  "passed": false,
  "violations": [
    {
      "rule": "min_spacing",
      "severity": "error",
      "location": [1.23, 0.45],
      "actual_nm": 62,
      "required_nm": 80
    }
  ],
  "summary": "1 error, 0 warnings"
}

Integration Flow

# 1. Run simulation in MetoSim
job = client.run(sim)
job.wait()

# 2. Export to GDS via MetoFab
gds = client.export_gds(job_id=job.job_id, pdk="generic_soi_220nm")

# 3. Run DRC
drc_result = client.run_drc(gds_url=gds.url, pdk="generic_soi_220nm")

if drc_result.passed:
    # 4. Generate fab recipe
    recipe = client.generate_recipe(gds_url=gds.url, process="ebl_si_220")
    print(f"Recipe ready: {recipe.url}")
